victim's heart rhythm through adhesive electrodes (some AED models require you to press an ANALYZE button). The computer analyzes the heart rhythm and advises the operator whether a shock is needed. AEDs advise a shock only to ventricular fibrillation and fast ventricular tachycardia. The electric current is delivered through the victim's chest wall through adhesive electrode pads. Why are AEDs important? AEDs are important because they strengthen the Chain of Survival. They can restore a normal heart
syndrome is a heart condition where there is an extra electrical pathway or circuit in the heart. The condition can lead to episodes of rapid heart also known as tachycardia. Wolff-Parkinson White syndrome, also known as WPW, is present at birth. People of all ages, even infants, can experience the symptoms related to WPW. Episodes of tachycardia often occur when people are in their teens or early twenties. Most of the time, a fast heart beat are not life threatening, but serious heart problems can occur
Atrioventricular node reentrant tachycardia Other than atrial fibrillation and atrial flutter, this is the most common supraventricular tachycardia seen in practice.11 A large minority of adults (up to 40% in some cohorts) are born with 2 pathways that can conduct electricity in the AV node, rather than 1. Under the right conditions, AV node reentrant tachycardia (AVNRT) can be initiated by a premature atrial or ventricular beat. If the 2 pathways are able to sustain a stable circuit, the atrium
formation continues in the dentate gyrus of the hippocampus (2). The hippocampus, which lies beneath the cortex is a major factor of learning and memory formation and can indirectly influence emotion. Progenitor cells which are present in the sub ventricular zone of the hippocampus are responsible for such growth as they produce daughter neuron cells through division (2). In the 1960s, Joseph Altman from MIT reported that new neurons were being produced in the dentate gyrus of the hippocampus of
flowing through the heart disrupts the normal coordination of heart muscles. These muscles lose their vital rhythm and begin a process known as ventricular fibrillation. Death soon follows. 0.25 Amps/250mA is equal to the current flowing through a 60W Bulb. What is ventricular fibrillation? The heart beats when electrical signals move through it. Ventricular fibrillation is a condition in which the heart's electrical activity becomes disordered. When this happens, the heart's lower (pumping) chambers
adults each year in this hi tech world (Zheng et al 2001). Therapeutic hypothermia (TH) may increase survival and reduce the amount of neurologic damage after cardiac arrest. According to the recent guidelines, comatose survivors of out-of-hospital ventricular fibrillation cardiac arrest should be cooled with internal or external cooling techniques to a target temperature of 32 °C to 34 °C (patients with in-hospital cardiac arrest or other primary rhythms may also be cooled. This target temperature should
The records have been reviewed. The member is an adult male with a birth date of 02/09/1959. He has a diagnosis of ischemic cardiomyopathy. His treating provider, Maria Costanzo, MD, recommended the Zoll LifeVest (wearable cardioverter defibrillator) for the following dates of service 09/02/2015, 10/02/2015, 12/02/2015, 01/02/2016-02/02/2016 (totaling 4 units). The carrier has denied coverage for the Zoll LifeVest as experimental and/or investigational and not medically necessary. A letter from
This condition can be treated various ways depending on “the type and frequency of arrhythmias, associated symptoms…, and the presence of structural heart disease” (Cleveland Clinic, 2014). Some patients may not need treatment at all, since they show not symptoms, since sometimes this condition can be naturally eliminated over the first year of life, but may still be required to have regular schedule appointments with the physician so the patients can be monitored. If symptoms are prevalent, the
this life save device called a automated external defibrillator. It has become the number one way to resuscitate a person who has had a cardiac arrest unwitnessed by emergency medical services and who is still in persistent ventricular fibrillation or ventricular tachycardia. Many people have played a big role in creating this device to become more efficient, smaller and easier to use for the general public. Here are just to name a few that played a part in the creation for this device: Claude Beck
Commotio cordis occurs after a blunt, non-penetrating blow to the precordial area of the chest wall that results in the induction of an often fatal ventricular fibrillation in a heart that does not have a preexisting structural or electrophysiological cardiovascular disease (Yabek, 2011). The blow is often perceived to be irrelevant, yet can cause a debilitating injury or even death. Death may be sudden or after a brief period of lucidity with purposeful movement prior to collapse (Yabek, 2011).
patient L.E. is a 73 year old male. The patient has no history of coronary artery disease or any problems with his heart. Yet, he suffered an event of ventricular fibrillation which he was shocked for followed by a massive heart attack while unaccompanied at a restaurant. Upon arrival to the Southcoast Hospital he went into ventricular tachycardia in the Emergency Room and was shocked a second time. According to the Southcoast critical care manual, these events are part of the inclusion criteria

References and resources used: Date reviewed: 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.
Supraventricular tachycardia (SVT) is a heart condition where the heart beats irregularly due to electrical abnormalities. It is fairly common, especially in children and women, yet unfamiliar to most people who are not diagnosed with it. There are three types of SVT: atrioventricular nodal re-entry tachycardia, atrial tachycardia, and Wolff-Parkinson-White syndrome. All three types have the same symptoms during episodes, which can last from seconds to hours and include palpitations, fatigue,
States can look into is having a defibrillator on site of any athletic activity. A defibrillator can be used when someone undergoes a sudden cardiac arrest. The defibrillator will deliver an electric shock to the heart to try to get it to stop the ventricular fibrillation which is when your heart rate increases and does not produce enough blood to the brian or other organs. A defibrillator was used in the case of Wes Leonard, but unfortunately it was not enough. As of right now I do not believe that
well as absorption, and on account of CSF being produced continuously, 16 oz each day to be exact, the blocking creates a surplus of CSF resulting in the said pressure against the brain tissue. The surplus accretion of CSF additionally motivates ventricular dilation in which the gaps between the brain, known as ventricles, abnormally widen.
malformations. It is estimated that “eight in 1,000 newborns” are said to have congenital heart defects, an abnormal aliment of the heart and blood vessels surrounding the heart. A ventricular septal defect (VSD) accounts for 25-30 percent of all congenital heart defects, with 1 in 500 infants born with a VSD. A ventricular septal defect or hole in the heart occurs along the septum between the ventricles of the heart. During fetal development the left and right ventricles are not separated, but as the

Cyanotic spells were observed when crying while on cardiac catheterization the baby was found to have tetralogy of fallot (TOF), pulmonary atresia, and ventricular septal defects with aorta lying over the septal defects. Baby J underwent surgery to repair the tetralogy of fallot. Two weeks after she develops chronic heart failure with laboratory investigations revealing metabolic acidosis and hyperglycemia
Artificial Heart Devices In its never ending pursuit of advancement, science has reached a crucial biotechnological plateau, the creation of artificial organs. Such a concept may seem easy to comprehend until one considers the vast knowledge required to provide a functional substitute for one of nature's creations. One then realizes the true immensity of this breakthrough. Since ancient times, humans have viewed the heart as more than just a physical part of the body. It has been thought the seat
after Victor Eisenmenger a man who had a patient who showed symptoms such as, breathing complications and skin that was turning a bluish color. The autopsy of this patient lead him to discover a ventricular septal defect [VSD] (El-Chami, 2014), that causes a hole in the wall on the right and left ventricular. This is the defect that begins when signaling for pulmonary artery hypertension, which progresses into more advanced stages of ES. This birth defect eventually causes patients to have various
The Bridge to Transplant It is estimated that there are nearly 50,000 people around the world that are in need of heart transplants. The average wait time for a donor heart is four to six months. For a patient with end-stage heart failure, a ventricular assist device or total artificial heart may be viable options to serve as a bridge to heart transplantation (Trivedi, 2014). The symptoms of heart failure can be treated in several ways depending on the severity of illness. In early stages, non-invasive
