Beneficial effect of Bradycardia Tachycardia Response (BTR) algorithm on VT detection in the presence of rate smoothing.

INTRODUCTION Rate smoothing algorithms, while known to help prevent ventricular tachyarrhythmias in some patients, have been shown to result in underdetection of ventricular tachycardia (VT) due to interaction between bradycardia pacing and tachycardia detection parameters. A new algorithm named Bradycardia Tachycardia Response (BTR) has been developed in order to prevent rate smoothing-induced...

1:1 AV tachycardia: what is the mechanism?

A 53-year-old man with nonischemic cardiomyopathy, left bundle branch block QRS morphology, and congestive heart failure underwent biventricular implantable cardioverter defibrillator (ICD) (Model V365; St. Jude Medical Corporation, Sunnyvale, CA, USA) placement for primary prevention of sudden cardiac death. The device was programmed with two zones: ventricular fibrillation (VF) zone at 210 bp...

Atrial 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...

A regular, wide-QRS complex tachycardia: what is the tachycardia mechanism?

A 45-year-old woman underwent an electrophysiology procedure because of a 20-year history of recunent episodes of paroxysmal tachycardia. The baseline sinus cycle length, atrial-His. and His-ventricular intervals were 700, 60, and 45 msec, respectively, and the QRS duration was 80 msec. Ventricular pacing at a cycle length of 300 msec induced a tachycardia that had a cycle length of 320 msec an...

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...
