This is a narrow complex tachycardia with a rate of 124 beats/min. The QRS morphology and axis are normal. The QTc is prolonged, at 529 ms (normal, 390-450 ms for men). The underlying P waves appear ...
This is a narrow-complex QRS rhythm which is quite fast. Looking closely at the last part of the QRS complex in leads V1 and V2, P waves can be seen. This is considered a "short RP tachycardia" and is ...
Atrioventricular reentrant tachycardia occurs when a reentrant circuit is present outside of the AV node through an abnormal conduction pathway that connects the atrium to the ventricles. If an action ...

SAN FRANCISCO -- Better indicators of high-grade atrioventricular (AV) conduction system abnormalities following transcatheter aortic valve replacement (TAVR) could be gleaned from an intraprocedural ...
It was our clinical impression that ECG evidence of pre-excitation (PE) is found more commonly in pts with tricuspid atresia (TA) than previously reported (0.29-1.3%). We attempted to determine a) the ...
Patients with atrioventricular (AV) block who don’t have an indication for cardiac resynchronization therapy (CRT) do better when treated with conduction-system pacing versus right ventricular septal ...
What Is the Heart Conduction System? The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our ...
