64 – US-ENGLISH
(69 %) were male. Mean patient age (± SD) was 74 ± 9 years.
Primary indications for implant were: 1st degree AV block (11.1 %),
2nd degree AV block (6.7 %), 3rd degree AV block (22.2 %), sinus
node dysfunction (62.2 %) or other (6.7 %).
Effectiveness results: To determine the effectiveness of SafeR
mode, the percentage of ventricular pacing provided over one month
was recorded from pacemaker memory.
Thirty-five patients contributed data to evaluate the percentage of
ventricular pacing provided with SafeR. Twenty-nine patients had 1
% or less ventricular pacing and six patients had a range of 28-97 %
ventricular pacing. The graph below shows the distribution of
ventricular pacing observed in patients with and without AV block as
a primary indication for implant.
The graph shows that many patients programmed to SafeR had less
than 1% ventricular pacing:
