Single-chamber versus dual-chamber pacing for high-grade atrioventricular block
Bedford; City Hospital, Birmingham 3 — T. Europace 13 The study was designed by Drs.
Blue vertical lines and bars indicate, for each specified subgroup, the hazard ratio for death from all causes and the associated 95 percent confidence intervals CIs for single-chamber pacing as compared with dual-chamber pacing. Free Full Text Mark Singletreff tegernsee. Kristin Newby, Richard L.

The mean annual rate of death from all causes during the first five years after pacemaker implantation was 7. There was an 18 percent reduction in the relative risk of atrial fibrillation with dual-chamber pacing but no significant difference in the rate of hospitalization for heart failure or in the occurrence of stroke.
The subgroup analysis showed that the presence or absence of selected baseline characteristics did not affect the influence of the pacing mode on the primary end point Figure 3 Singletreff moers 3 Effect of Pacing Mode on Deaths from All Causes, According to Subgroups.
Superior cardiac hemodynamics of atrioventricular synchrony over rate responsive pacing at submaximal exercise: Clinical trials of pacing mode selection. The differences in complication rates were principally due to problems with the placement or stability of atrial leads.
Are We Getting to the Heart of the Matter?. Page, Barbara Riegel, Lynn G. Cardiac pacing is the established treatment for high-grade atrioventricular block, but the appropriate pacing mode remains the subject of debate.
Mark Estes, Roger A. A prespecified secondary analysis involved the separate comparisons of fixed-rate and rate-adaptive single-chamber pacing with dual-chamber pacing. CrossRef Marcelle D.
While dual-chamber is associated with lower incidence of atrial fibrillation, stroke and heart failure in non-randomized studies, Dr. Tipping; Derriford Hospital, Plymouth 29 — C.
Within the single-chamber group, assignment to fixed-rate or rate-adaptive pacing was randomly determined. All statistical tests were two-tailed.
Patients were randomly assigned, up to 24 hours before the scheduled implantation, to receive either a fixed-rate or rate-adaptive single-chamber ventricular pacing system or a dual-chamber system with or without sensor-modulated rate adaptation. CrossRef 63 Anne M. CrossRef 40 Bruce S.
