What did studies of single-chamber pacemaker find?

1

Studies of single-chamber pacemaker measured one outcome, daily activity level.

Daily activity level

downin humans1

1 study

  1. Single-chamber pacemaker is linked with lower daily activity level in humans (emergent complete heart block) (0.57 ± 0.3 vs. 1.5 ± 1.1 hours).

    “lower daily activity levels (0.57 ± 0.3 vs. 1.5 ± 1.1 hours of activity, p=0.016) than DDD recipients.”

What is single-chamber pacemaker linked with?

2

Studies link single-chamber pacemaker with 2 measures: congestive heart failure mortality and mortality.
