Widening of the QRS complex during atrial pacing: what is the mechanism?
An electrophysiologic procedure was performed in a 50-year-old man with a 20-year history of paroxysmal tachycardia. During sinus rhythm, the atrial-His (AH) interval was 70 msec, the His-ventricular (HV) interval was 45 msec, and the QRS width was 80 msec. During atrial pacing at a cycle length of 290 msec, there was widening of the QRS complex (Fig. 1). The transition from a narrow to wide QR...
متن کاملAtrial pacing during a narrow QRS complex tachycardia: what is the mechanism?
A 25-year-old woman with a 5-year history of paroxysmal supraventricular tachycardia underwent an electrophysiologic procedure. The baseline sinus cycle length, atrial–His-bundle (AH) interval, and His-bundle–ventricular (HV) interval were 750, 60, and 50 msec, respectively. Paroxysmal supraventricular tachycardia with a cycle length of 320 msec was induced by programmed atrial stimulation with...
متن کاملInteresting response of narrow QRS tachycardia to premature atrial complex. What is the mechanism?
Fig.1 shows a premature atrial complex (PAC) introduced during a narrow QRS tachycardia. What is the response and what is the interpretation? The tachycardia is a regular RBBB tachycardia with cycle length of 440 ms and ventriculo-atrial interval of 30 ms. There is near simultaneous activation of atrium and ventricle during tachycardia. Presence of His deflection prior to the QRS makes ventricu...
متن کاملAdenosine-Responsive wide QRS complex tachycardia: what is the mechanism?
A 45-year-old man presented with an acute anterior wall myocardial infarction and underwent successful percutaneous transluminal angioplasty of the left anterior descending coronary artery. Twenty-four hours later, a wide QRS tachycardia at a rate of 108 beats/min that had a QRS duration of 150 msec was noted by telemetric monitoring. There were no symptoms associated with the tachycardia. A 12...
متن کاملChanging QRS Morphology: What is the mechanism?
ECG in sinus rhythm with ventricular preexcitation and changing QRS morphology was seen that was initially interpreted as the multiple accessory pathway from elsewhere. (Figure 1A). The following mechanisms are potentially involved in the electrogenesis of changing QRS morphology in WPW syndrome: 1) multiple accessory pathways1; 2) simultaneous occurrence of aberrant atrioventricular conduction...
