The most common test used to diagnose ventricular tachycardia is an electrocardiogram (ECG/EKG) . An EKG records your heart’s electrical activity. Electrodes (small sticky patches) are placed on your chest and arms to record the heart’s rhythm, and the pattern prints on graph paper.

Read moreIs atrial fibrillation a reentry mechanism?
Contemporary theories of the mechanism of atrial fibrillation require an understanding of re-entry as a mechanism of arrhythmogenesis . Re-entry, which is not a disorder of impulse formation but rather a disorder of impulse propagation, occurs when an impulse travels around an abnormal circuit repetitively.
Read moreWhat stimulates atrial fibrillation?
Advanced age is one of the biggest triggers of AFib. It’s one of the most common reasons for an irregular heartbeat in people over 65, and 70 percent of people with AFib are between the ages of 65 and 85.
Read moreWhat is the pathophysiology of atrial fibrillation with RVR?
Rapid ventricular rate or response (RVR) AFib is caused by abnormal electrical impulses in the atria , which are the upper chambers of the heart. These chambers fibrillate, or quiver, rapidly. The result is a rapid and irregular pumping of blood through the heart.
Read moreWhat happens during a fibrillation?
During atrial fibrillation, the heart’s upper chambers (the atria) beat chaotically and irregularly — out of sync with the lower chambers (the ventricles) of the heart . For many people, A-fib may have no symptoms. However, A-fib may cause a fast, pounding heartbeat (palpitations), shortness of breath or weakness.19 Eki 2021
Read moreWhat is the difference between fibrillation and arrhythmia?
Atrial fibrillation (AF) is a form of arrhythmia, or irregular heartbeat, in which the atria (the two small upper chambers of the heart) quiver instead of beating effectively . It is one of the most common forms of cardiac arrhythmia, affecting 0.4% of the general population and 5 to 10% of persons over 65 years of age.
