A‐V‐V‐A response to single atrial premature depolarization in a narrow QRS tachycardia: What is the mechanism?

We present an atypical response to single atrial premature depolarization (APD) in a long RP’ tachycardia. APD advanced the His‐bundle potential immediately after it and resulted in a VA block; however, tachycardia persisted and consequently exhibited an A‐V‐V‐A response. We propose the mechanism fo...

description We present an atypical response to single atrial premature depolarization (APD) in a long RP’ tachycardia. APD advanced the His‐bundle potential immediately after it and resulted in a VA block; however, tachycardia persisted and consequently exhibited an A‐V‐V‐A response. We propose the mechanism for an A‐V‐V‐A response to APD in a long RP' tachycardia.[Image: see text]
