Sinus Tachycardia
Sinus tachycardia is a kind of fast heartbeat. In sinus tachycardia, the heart beats more than 100 times a minute. Sinus tachycardia starts in a part of the heart called the sinus node. Sinus tachycardia may be harmless, or it may be a sign of a serious condition.
CAUSES
This condition may be caused by:
• Exercise or exertion.
• A fever.
• Pain.
• An injury.
•

• Suddenly noticing your heartbeat (cardiac awareness).
• Dizziness.
• Tiredness (fatigue).
• Shortness of breath.
• Chest pain.
• Nausea.
• Fainting.
DIAGNOSIS
This condition is diagnosed with a physical exam and tests, such as:
• Blood tests.
• An electrocardiogram (ECG). This test measures the electrical activity of the heart.
• Holter monitoring. For this test, you wear a device that records your heartbeat for one or more days.
You may be referred to a heart specialist (cardiologist).
TREATMENT
Treatment for this condition depends on the cause or underlying condition. Treatment may involve:
• Treating the underlying condition.
• Taking new medicines or changing your current medicines as told by your health care provider.
• Making changes to your diet or lifestyle.
• Practicing relaxation methods.
HOME CARE INSTRUCTIONS
Lifestyle changes
• Do not use any tobacco products, such as cigarettes, chewing tobacco, and e-cigarettes. If you need help quitting, ask your health care provider.
• Learn relaxation methods, like deep breathing, to help you when you get stressed or
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
It increases during physical exercise to deliver extra oxygen to the tissues and to take away excess carbon dioxide. As mentioned at rest, the heart beats around 75 beats per minute but during exercise this could exceed to 200 times per minute. The SAN controls the heart rate. The rate increases or decreases when it receives information by two autonomic nerves that link the SAN and the cardiovascular centre in the medulla of the brain. The sympathetic or accelerator nerve speeds up the heart. The synapses at the end of this nerve secretes noradrenaline. A parasympathetic or decelerator nerve, a branch of the vagus nerve slows down the heart and the synapses at the end of this nerve secretes
In this article, it tells how an EKG scan is on grid paper and each small block, which is one millimeter (mm) long, represents 0.04 seconds and each larger box, which is five millimeters long, represents 0.2 seconds. On a EKG scan, the voltage of the heart is measured in millivolts (mV) along the y-axis. On the scan grid, ten millimeters is equal to one millivolt. According to this source, in order to calculate the beats per minute (BPM), one divides the number of number of large boxes between each heart beat (QRS wave) in 300 small boxes. However, that used for a more consistent and steady heart rate. For a more varied and irregular rhythm, one has to count the number of QRS waves in six seconds and then multiply that number by ten. For an example, if there are eight QRS waves, then the estimated heart rate would be 80
Overall, the aim of this experiment involved the examination of stimuli that triggered the bradycardia reflex, in relation to circulatory and physiological responses that occur in humans during dive reflex. Due to the different factors being generated the dive response was evoked to different extents. All variables including MAP, SV, CO, HR and TPR were monitored and varied (5). The basal measurements fell all within normal range, with respect to the conditions.
A normal heartbeats at a rate of 60-100 beats per minute. Cardiac dysrhythmia occurs when there is a disturbance in the normal rhythm of the heart. Atrial fibrillation and atrial flutter are two of the most common types of cardiac dysrhythmia. “These atrial arrhythmias may interfere with the heart’s ability to pump blood properly from its upper chambers (atria). The atria may not always empty completely, and blood remaining there too long may stagnate and potentially clot. Such clots may travel to other parts of the body, where they may cause blockages in the blood supply to the limbs, brain or heart. ("Cardiac Arrhythmias." Cardiac Arrhythmias. N.p., n.d. Web. 11 Dec. 2013, retrieved from http://www.hopkinsmedicine.org/) The American Heart Association reports that 383,000 emergency out-of-hospital treated cardiac arrests occur in the United States. A number of factors can cause cardiac dysrhythmia; smoking, heavy alcohol use, drugs (ie; cocaine or amphetamines), some prescription or over-the-counter medicines, or even too much caffeine or nicotine.

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).

When caring for patients it is fundamentally important to have a good selection of up to date evidence Based Practice clinical articles to support research strategies, this allows professionals to assemble the most resent and accurate information known which enables them to make decisions tailored to the individual’s plan of care. It is essential to have clinical expertise and have the involvement from the individual patient, they must have full engagement and incorporation in order to have the accurate evaluation.

Other techniques to reducing stress, is listening to music, pampering yourself a massage/spa day, talking it out to family/friends, baking/cooking, praying/meditating and even playing with your pet.
Find healthy ways to cope with stress, such as exercise, meditation, or spending time with people you care about.
...Three techniques that I use and other people can use to cope with stress are practicing emotion-focused coping, building time-management skills, and regularly practicing meditation. By using these techniques, I am able to lower my stress that I have from homework, socializing, and the newfound responsibilities I have gained since attending college.
During this course I learned many stress management techniques. One of the first stress management techniques I learned was creating a list of things to do in order of importance. Before using this technique I left things to do all at once. This technique helped me by equaling out my work load. Another technique for stress I learned was yoga. Yoga helps me by relaxing my entire body. This technique helps me forget about the things that cause my stress. I use this technique when I have something on my mind that is
Smoking cigarettes can be very harmful to your life with so many health issues, such as heart disease, cancer and emphysema. Some people think it’s not a huge issue smoking cigarettes but it’s a great way to lose ten years of your life. You lose lots of money, a lifetime of health issues, and cause you to have yellowing of the teeth and bad breath .There is way too many health risks involved to start using this drug. Say no to cigarettes you will be healthier in the end then to continue on this wrongful path.
