The heart is one of the most important organs in the body. All living things have a heartbeat, rather it be a healthy one or a not so healthy one. If your heart is not beating then I am saddened to tell you that you are dead, not that you would be able to hear me or care what I have to say. The four chambers consist of the right and left atrium and right and left atrium. Each of the chambers has valves. The tricuspid valve, mitral valve, pulmonary valve, and the aortic valve are their names. Their purpose is to allow blood to move forwards through the heart and to make sure that it doesn’t flow backwards into the previous chamber.

A normal resting heart rate for adults range from 60 to 100 beats a minute. (2) This varies according to fitness, age, exertion and general health. Each heart beat is triggered by an electrical pacemaker - a group of cells in the heart that have the ability to generate electrical activity. They cause the heart and make it contract. The largest natural pacemaker of the heart is called the sinoatrial or SA node and is found in the right atrium. From it, specialized groups of cells that carry the electrical charge lead off to the rest of the heart. (3)

How to describe or label ventricular tachycardia is complicated and the doctors have to be correct in diagnosing a patient with V-tach. Most of the time, a rapid heart rate can start in either the left or right ventricle. (5) Ventricular tachycardia which lasts more than 30 seconds is referred to as sustained ventricular tachycardia. A period of three to five rapid beats is called a salvo, and six beats or more lasting less than 30 seconds is called nonsustained ventricular tachycardia. Rapid ventricular rhythms are more serious than rapid atrial rhythms because they make the heart extremely inefficient. They also tend to cause more severe symptoms, and have a much greater tendency to result in death. Although it is mostly known to be one of the life-threatening abnormal rhythms,...
