Arrhythmia
I am doing my report on Arrhythmia. It affects the cardiac muscle, the heart. Arrhythmia causes three types of problems. It causes the heart to pump too slowly (bradycardia), it causes the heart to pump too fast (tachycardis), and it causes the heart to skip beats
(palipations).
Bradycardia can be very serious. Some of the symptoms are loss of consciousness, heart failure, or death. Slow heart rates are caused by heart block. The hearts natural pace-maker fails to be conducted to the ventricles, the hearts main pumping chambers.
Some treatments can be used. An electronic pace-maker can be inserted and it will send electronic impulse to the heart stimulating it to beat at a normal rhythm. Pace-makers are only inserted when the heart beats too slow.
Tachycardis can also be very serious. It can lead to disabling symptoms and even death. When you have Tachycardis your heart rate is above 100 beats per minute. Tachycardis is caused by heart injuries from past times. Tachycardis usually occurs months or years after a heart attack. A treatment for Tachycardis can be inserting a device called a defibrillator. A defibrillator will detect and treat abnormally fast heart rhythms. The defibrillator monitors the heart and automatically gives electric shocks before Arrhythmia causes permanent damage. If the person does not have a defibrillator a strong electric shock will be given. The cause of Tachycardis is by something not functioning properly in the atria. They are sometimes stimulated by anxiety. Too much caffeine or alcohol and certain drugs can also be the cause. Attacks might last a few minutes or several days. They can be serious and sometimes not serious.
Palpitations happen when your heart skips beats. Palpitations have many different symptoms. Some of these symptoms are dizziness, fatigue or fainting as a result of the brain not getting enough oxygen rich blood, chest pain, shortness of breath, and death
(which occurs rarely). Palpitations are caused by high blood pressure, mistral valve prolapse, Hyperthyroidism, Anemia, coronary artery disease, or stress, Anxiety, panic attacks, stimulants such as caffine, nicotine, and alcohol, heavy excursus, high consumption of nutmeg.
There some treatments which you can do. You could try to hold your breath briefly, take a slow drink of cold water, wash your face in cold water, cough several times, and hold your nose and blow (it will pop
There are several different heart problems that show up as an abnormal EKG reading. For example, a heart block can occur when there is a delay in the signals coming from the SA node, AV node, or the Purkinje fibers. However, clinically the term heart block is used to refer to an AV block. This delays or completely stops communication between the atria and the ventricles. AV block is shown on the EKG as a delayed or prolonged PR interval. The P wave represents the activity in the atria, and the QRS complex represents ventricular activity. This is why the PR interval shows the signal delay from the AV node. There are three degrees of severity, and if the delay is greater than .2 seconds it is classified as first degree. Second degree is classified by several regularly spaced P waves before each QRS complex. Third degree can be shown by P waves that have no spacing relationship to the QRS complex. Another type of blockage is bundle branch block. This is caused by a blockage in the bundle of His, creating a delay in the electrical signals traveling down the bundle branches to reach the ventricles. This results in a slowed heart beat, or brachycardia. On an EKG reading this is shown as a prolonged QRS complex. A normal QRS is about .8-.12 seconds, and anything longer is considered bundle branch block. Another type of abnormal EKG reading is atrial fibrillation, when the atria contracts very quickly. On the EKG this is shown by no clear P waves, only many small fibrillating waves, and no PR interval to measure. This results in a rapid and irregular heartbeat. On the other hand, ventricular fibrillation is much more serious and can cause sudden death if not treated by electrical defibrillation.
In this lab, I took two recordings of my heart using an electrocardiogram. An electrocardiogram, EKG pg. 628 Y and pg. 688 D, is a recording of the heart's electrical impulses, action potentials, going through the heart. The different phases of the EKG are referred to as waves; the P wave, QRS Complex, and the T wave. These waves each signify the different things that are occurring in the heart. For example, the P wave occurs when the sinoatrial (SA) node, aka the pacemaker, fires an action potential. This causes the atria, which is currently full of blood, to depolarize and to contract, aka atrial systole. The signal travels from the SA node to the atrioventricular (AV) node during the P-Q segment of the EKG. The AV node purposefully delays
There are four different categories of treatment: lifestyle changes, surgical procedures, non-surgical procedures, and medications. Lifestyle changes include having a healthy diet; increasing physical activity; eliminating cigarettes, alcoholic beverages, and illicit drugs; and getting enough rest and sleep; losing excess weight. These lifestyle changes are to lower the patient’s blood pressure, cholesterol, and reducing any other future medical conditions. There are also surgical options to help cure, prevent, or control cardiomyopathy. Surgical method include a septal myectomy, surgically implanted devices, and a heart transplant. A septal myectomy is used to specifically treat hypertrophy cardiomyopathy which is where the heart muscle cells enlarge and cause the walls of the ventricles to thicken. The thickening of the walls may not affect the size of the ventricles but instead may affect the blood flow out of the ventricle. Usually along with the ventricles swelling, the septum in between the ventricles can become enlarged and block the blood flow causing a heart attack. When medication is not working well to treat hypertrophic cardiomyopathy, a surgeon will open the chest cavity and remove part of the septum that is blocking blood flow. Surgically implanted devices include a pacemaker, a cardiac resynchronization therapy device, a left ventricular assist device, and an implantable
Atrial fibrillation (AF) is a cardiac arrhythmia. It is the most common arrhythmia and it has implications for patients and anaesthetists alike. The anaesthetist must take into consideration the physiological and pharmacological implications of this common arrhythmia.
The Vikings were people that raided many towns and monasteries for silver and other precious items. They mostly raided monasteries because they were the places with the most silver and expensive items. The Vikings were at first mysterious worriers and them became well known. So where did these mysterious warriors come from? They came from a place called Scandinavia. Scandinavia was built up of multiple countries like Denmark, Norway, Sweden, Finland and Iceland. The word Viking means sea-raiders in scandinavian and they didn’t actually wear horns on their head, their helmet was round.
The two focal figures are illustrated with complementary colors, the woman 's dress being orange, and the man’s pants being blue. Benton uses these colors to bring life into the painting. The background is made up mostly of earthy colors like, greens, browns, and greys and a light blue for the sky. Benton seems to add white to every color he uses, which gives the painting an opaque look. The deepest hues found in this painting are the blue one the man’s pants and the orange on the woman’s dress, everything else around them looks washed out and Benton does this to emphasize his focal points
To make sure it is a fair test; the procedure is repeated a couple of
The Vikings were very culturally rich in many ways including religion. Vikings were pagans who had a highly personalized religion that involved multiple gods and goddesses( Grabianowski para.1). There were two groups of gods, the “Aesir” and “Vanir.” Both groups of gods lived in “Asgard” while the humans lived in “Midgard”. The gods traveled around the universe by using a rainbow bridge also known as the “Bifrost” (Grabianowski para.2). Even though there were two groups of gods, three gods were in both groups: the main god, Odin, who is the god of war, Thor, the hammer wielding god of thunder, and Freyja, the goddess of beauty and fertility (Grabianowski para.2). Most every Viking believed that warriors who died nobly in battle would go to a warrior heaven called “Valhalla.” In “Valhalla” every warrior would have a chance to fight in a huge battle and if they were to die in battle that day, later that night they would rise again and join everyone for a huge feast with Odin (Grabianowski para.3). The Vikings did have traditions even though they didn't have an organized religion.
...of goods with the Vikings. In everyday life, every one of us is in search of the right food, the best and warmest clothing, and the perfect place to live. Religion is still important to the American people, just like it was to the Vikings way back then. And even today, the American people exchange goods through the use of trading. However, in the present, we use plenty of money to get the supplies we need to survive. The Vikings culture can be seen as a way of survival. If they didn’t work hard enough to get the items they needed to survive, they would die off. So, the Vikings were more than a bunch of wild men running around northern England destroying cities and killing people. They strived to lead a healthy life to the fullest extent possible during their time. Many people in northern England who are descendants of the Vikings are proud to be a progeny of such a dominant and prestigious culture.BIBILIOGRAPHY
The heart is a pump with four chambers made of their own special muscle called cardiac muscle. Its interwoven muscle fibers enable the heart to contract or squeeze together automatically (Colombo 7). It’s about the same size of a fist and weighs some where around two hundred fifty to three hundred fifty grams (Marieb 432). The size of the heart depends on a person’s height and size. The heart wall is enclosed in three layers: superficial epicardium, middle epicardium, and deep epicardium. It is then enclosed in a double-walled sac called the Pericardium. The terms Systole and Diastole refer respectively and literally to the contraction and relaxation periods of heart activity (Marieb 432). While the doctor is taking a patient’s blood pressure, he listens for the contractions and relaxations of the heart. He also listens for them to make sure that they are going in a single rhythm, to make sure that there are no arrhythmias or complications. The heart muscle does not depend on the nervous system. If the nervous s...
Cardiac dysrhythmias come in different degrees of severity. There are heart conditions that you are able to live with and manage on a daily basis and those that require immediate attention. Atrial Fibrillation is one of the more frequently seen types of dysrhythmias (NIH, 2011). The best way to diagnosis a heart condition is by reading a cardiac strip (Ignatavicius &Workman, 2013). Cardiac strips play an chief part in the nursing world allowing the nurse and other trained medical professionals to interpret what the heart is doing. In a normal strip, one can clearly identify a P wave before every QRS complex, which is then followed by a T wave; in Atrial Fibrillation, the Sinoatrial node fires irregularly causing there to be no clear P wave and an irregular QRS complex (Ignatavicius & Workman, 2013). Basically, it means that the atria, the upper chambers of the heart, are contracting too quickly and no clear P wave is identified because of this ‘fibrillation’ (Ignatavicius & Workman, 2013).
...ed to survive. Without this people couldn’t live and then either died or became villagers in Normandy or other countries. So yes, there was a reason behind their way of living. But it was a reason that most people now a days would understand. Everybody wants to live and care for their families. At the time, becoming a Viking was the only choice. Also, most parts of Scandinavia were bad for growing crops so they needed to steal it from other countries and villages. Vikings had a good, legitimate reason for stealing and the way they are for the most part. Perhaps there could have been a better way of finding food and caring for their families; but medieval times were violent and it may have seemed as a good way to do it. But was it really? No one really knows what could have been done instead and if it was really necessary to do. At the time it seemed to be correct.
Vikings were a Norse-speaking, seafaring people who lived from the 8th to 11th centuries, mainly in Scandinavia. They were expert sailors who, starting in late 700s, looted and burned civilizations along rivers and coasts of Europe and Asia. They traded, sailed and explored across the Mediterranean Sea and Atlantic Ocean, opening trade routes that connected Europe to the Mediterranean lands. During this time, some of the population settled in the kingdoms that they were exploring; namely England, Ireland, northern France and Russia. One of the main influences that the surrounding cultures had on them was through religion. As the Vikings came in contact with Christianity through their raids, it began to form a unique fusion of Christian influence, while still holding on to many aspects of their pagan lifestyle. Not many primary sources remain from pre-Christian Viking society as much of their culture was destroyed during the Christianization process. The extremely strong oral tradition and the artifacts that remain are what the knowledge of the culture is based on. The pagan culture interests me, as I can still examine influences of it on my Scandinavian family today.
In the earliest years of the Vikings, there was little history recorded due to the polytheistic views that they followed. After the Vikings converted to Christianity, there were eventually written documents created pertaining to their existence. In Viking Warfare, I.P. Stephenson states that the Vikings “first described attack took place in AD 789”(11). The Vikings were also known as Norsemen. They were great storytellers, and that is perhaps how society knows so much about them today. The stories that the Norsemen told were called Sagas. Today, Vikings are often depicted as murderous savages, but while they were not pillaging villages they were actually quite a peaceful civilization. There were three countries that Vikings evolved from; Norway, Denmark, and Sweden. Although it may seem that all Vikings were on the same side, they quarreled with each other as well. Despite the fact that Viking battles were bloody and gruesome they were also known to be the most hygienic out of many of the earlier civilizations. There was not a huge percentage of Vikings that went out and raided but when they did they made a huge impact on what Vikings are now known for. The success of Viking warfare and raids relied primarily on the uses of armor, weapons, long ships, and battle tactics.
What was the history behind these men called vikings? Around A.D. 800 to the 11th century, a large amount Scandinavians left their homes in search of riches. These men eventually gained the name Vikings or Norsemen which come from North Man, a homage to their homeland. Viking raids started small, pillaging structures around the coast, particularly undefended monasteries, in the British Isles. Over the next three hundred years, they would be known far and wide as pirates, raiders, traders and settlers. Contrary to popular belief, Vikings were not a race, linked by ties of common ancestry or patriotism, and could not be defined by any single definition. Most of the Vikings, whose accomplishments are best known to come from Denmark, Norway and
