Atrioventricular reentrant tachycardia (AVRT) is a rhythm problem in your heart that makes it beat too fast. It results from an extra connection between your upper and lower chambers. You might hear ...

Atrioventricular nodal reentrant tachycardia (AVNRT) is a common supraventricular arrhythmia that arises due to a reentrant circuit located in or near the atrioventricular node. This condition ...

The Essence of Resetting: Interaction Between the Cardiac Rhythm and the Perturbation Generated In the example of Figure 1 the reason why the ventricular premature contraction produces a ...

Reentry arrhythmia occurs when electrical signals in the heart deviate from their usual path, creating a loop that causes repeated stimulation and disrupts the heart’s rhythm. Symptoms of reentry ...

This is a narrow QRS complex tachycardia with a very fast heart rate (about 250 beats per minute). It is quite difficult to indentify any P wave activity to determine the exact etiology. Most commonly ...

Ventricular tachycardia arises from an abnormal electrical focus or circuit in the myocardium of the ventricle and is usually manifested as a tachyarrhythmia with a wide QRS complex on ...

Tachycardia is a type of arrhythmia when your heart rate is faster than normal. A healthy resting heart rate for most adults is between 60 and 90 beats per minute (bpm), but adults with tachycardia ...

Tachycardia refers to a fast resting heart rate, usually over 100 beats per minute (bpm) in adults. Some people experience no symptoms, but others may notice palpitations and lightheadedness, among ...

Resetting is easily recognized because it is easy to detect whether the pause after one or two extrastimuli is fully compensatory (usually less than but occasionally more than fully compensatory). In ...
