TL;DR: For patients with standard indications for ICD therapy, no indication for cardiac pacing, and an LVEF of 40% or less, dual-chamber pacing offers no clinical advantage over ventricular backup pacing and may be detrimental by increasing the combined end point of death or hospitalization for heart failure.
Journal ArticleDOI
Ventricular pacing or dual-chamber pacing for sinus-node dysfunction
Gervasio A. Lamas,Kerry L. Lee,Michael O. Sweeney,Russell Silverman,Angel R. Leon,Raymond Yee,Roger A. Marinchak,Greg C. Flaker,Eleanor Schron,E. John Orav,Anne S. Hellkamp,Stephen Greer,John H. McAnulty,Kenneth A. Ellenbogen,Frederick A. Ehlert,Roger A. Freedman,N.A. Mark Estes,Arnold J. Greenspon,Lee Goldman +18 more
TL;DR: Overall, dual-chamber pacing offers significant improvement as compared with ventricular pacing, and reduces the risk of atrial fibrillation, reduces signs and symptoms of heart failure, and slightly improves the quality of life.
Journal ArticleDOI
Atrial High Rate Episodes Detected by Pacemaker Diagnostics Predict Death and Stroke Report of the Atrial Diagnostics Ancillary Study of the MOde Selection Trial (MOST)
Taya V. Glotzer,Anne S. Hellkamp,John F. Zimmerman,Michael O. Sweeney,Raymond Yee,Roger A. Marinchak,James R. Cook,Alexander Paraschos,John C. Love,Glauco Radoslovich,Kerry L. Lee,Gervasio A. Lamas +11 more
TL;DR: AHRE detected by pacemakers in patients with SND identify patients that are more than twice as likely to die or have a stroke, and 6 times as likelyto develop atrial fibrillation as similar patients without AHRE.
Journal ArticleDOI
Quality of life and clinical outcomes in elderly patients treated with ventricular pacing as compared with dual-chamber pacing. Pacemaker Selection in the Elderly Investigators.
Gervasio A. Lamas,Endel J. Orav,Bruce S. Stambler,Kenneth A. Ellenbogen,Elena B. Sgarbossa,S K Huang,Roger A. Marinchak,N A Estes rd,Gary F. Mitchell,Eric H. Lieberman,Carol M. Mangione,Goldman L +11 more
TL;DR: Quality of life improved significantly after pacemaker implantation, but there were no differences between the two pacing modes in either the quality of life or prespecified clinical outcomes (including cardiovascular events or death).
Journal ArticleDOI
Phase 2 early afterdepolarization as a trigger of polymorphic ventricular tachycardia in acquired long-QT syndrome : direct evidence from intracellular recordings in the intact left ventricular wall
TL;DR: This study provides the first direct evidence from intracellular action potential recordings that phase 2 EAD can be generated from intact ventricular wall and produce a trigger to initiate the onset of TdP under QT prolongation.
