A Narrow QRS Complex Tachycardia:
نویسنده
چکیده
An 80-year-old man underwent an electrophysiologic procedure because of recurrent episodes of supraventricular tachycardia. Episodes of nonsustained narrow QRS complex tachycardia occurred spontaneously after catheter placement. Examples of the onset and termination of an episode of tachycardia are shown in Figures 1 and 2, respectively. What is the mechanism of the tachycardia? What is the level of AV block?

Termination of a narrow QRS-complex tachycardia: what is the mechanism?
A 27-year-old man with a 10-year history of recurrent episodes of paroxysmal supraventricular tachycardia underwent an electrophysiologic procedure. The baseline sinus cycle length was 860 msec, and the atrial-His (AH) and Hisventricular (HV) intervals were 80 and 45 msec, respectively. A narrow QRS-complex tachycardia was induced by atrial overdrive pacing. The cycle length of the tachycardia ...
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 کاملWidening 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 کاملRegular narrow QRS and regular wide QRS tachycardias in a woman with mitral regurgitation of uncertain etiology.
A 64-year-old woman had been experiencing short episodes of rapid regular heart beating for nearly a year. The bouts became frequent and lengthy, resulting in a hospital admission a month earlier when intravenously administered adenosine terminated an episode. She was discharged on diltiazem, but the bouts of tachycardia continued and were accompanied by light-headedness and sometimes nausea. W...
متن کاملNarrow QRS tachycardia to wide QRS tachycardia with LBBB morphology. What is the mechanism?
A 42-year-old woman was referred for radiofrequency catheter ablation of narrow QRS tachycardia that was terminated with intravenous adenosine. Baseline twelve-lead ECG was normal during sinus rhythm and transthoracic echocardiography demonstrated no evidence of structural heart disease. The electrophysiological study showed a normal AH interval of 114 ms and HV interval of 37 ms during sinus r...
