resulting in AVRT. Findings on ECG include the following: a narrow complex tachycardia; and variable findings, depending on the direction of the circuit and location of the accessory conduction ...

Any tachycardic rhythm with a left or right bundle branch block that is NOT ventricular tachycardia is considered "supraventricular tachycardia with aberrancy". This would even include sinus ...

The initial differential diagnosis of supraventricular tachycardias should focus on the ventricular response, not on atrial depolarization as observed on the ECG. The first step is to determine ...

Overall, the most common mechanism in this cohort was AVNRT followed by AVRT and atrial tachycardia. What are the different mechanisms of SVT? Understanding the underlying mechanism is useful in ...

The key difference is that AVRT is due to an additional pathway that can lead to irregular heart rhythms. An electrocardiogram (ECG) can help doctors differentiate between the two. PSVTs ...

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 ...
