Optimization of Device Programming for Cardiac …
Devices may have an optional premature ventricular contraction (PVC) response that extends PVARP duration in response to a PVC, in order to avoid pacemaker-mediated tachycardia.
Advanced ICD Troubleshooting: Part II - Page 5 - Medscape
Pacemaker algorithms—such as those designed to terminate pacemaker-mediated tachycardia—may promote inappropriate shocks by temporarily suspending ventricular pacing and permitting double ...
Resetting and Entrainment of Reentrant Arrhythmias: Part I
The tachycardia is reset because the sum of the two intervals encompassing the extrastimulus (860 ms) is less than twice the tachycardia cycle length (880 ms). So the 480-ms pause after the ...

Pacing or Ablation: Which Is Better for Tachy-Brady Syndrome?
More patients in the PM group were on AADs (PM 40.4%, ABL 4.7%, P < 0.001) while sinus rhythm maintenance was remarkably higher in the ABL group at the end of follow-up (83.7% vs 21.1% in PM group ...
Long-Term Follow-Up of Patients Supplied with Single-Chamber …
Patients were followed-up for a mean of 52 ± 14 months. Mortality and arrhythmogenic morbidity were assessed. All-cause mortality was 21% for single-chamber and 31% for dual-chamber ICD ...
Long-Term Follow-Up of Patients Supplied with Single-Chamber
Between January 1998 and March 2000, a total of 100 patients with the indication for the implantation of an ICD and with absence of permanent/persistent atrial tachyarrhythmias were randomly ...
Pacing or Ablation: Which Is Better for Tachy-Brady Syndrome?
After pacemaker insertion, 84.2% (48/57) of the patients in the PM group were on AADs to manage AF whereas none in the ABL group were on AADs after ablation. At the end of follow-up, only two (4.7 ...
UKPACE Trial: Pacing Mode Does Not Effect Mortality - Medscape
April 15, 2003. 0. April 15 -- Dual-chamber (DDD) pacing offers no mortality benefit over single-chamber pacing in elderly patients with high-grade atrioventricular (AV) block, according to the ...
