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 ...
Theoretically, any reentrant VT can be terminated by a critically timed pacing stimulus that depolarizes the excitable gap. This principle is shown schematically in Figure 2. In panel A, the head of ...
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 ...
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 ...
