Key result
Electrophysiological study with premature atrial extra stimuli and His refractory premature ventricular extra demonstrated that the mechanism of the long RP tachycardia was orthodromic AV re-entry involving a slowly conducting left lateral accessory pathway, which was successfully ablated.
Why the study?
What is the mechanism of narrow QRS tachycardia in a 60-year-old woman when premature atrial extra stimuli are delivered?

What is the mechanism of narrow QRS tachycardia in a 60-year-old woman when premature atrial extra stimuli are delivered?
This case report presents an electrophysiological tracing to discuss the mechanism of a narrow QRS tachycardia responding to premature atrial extrastimuli.
No takes yet. Share an insight, caveat, or question.
May aid differential diagnosis of long RP tachycardia; extends EP maneuvers but remains hypothesis-generating.
Nair et al. (2016) conducted a case report in Narrow QRS tachycardia (n=1). Electrophysiological study and radiofrequency catheter ablation was evaluated on Mechanism of tachycardia. Electrophysiological study with premature atrial extra stimuli and His refractory premature ventricular extra demonstrated that the mechanism of the long RP tachycardia was orthodromic AV re-entry involving a slowly conducting left lateral accessory pathway, which was successfully ablated.
