Outcome Measures

Primary Outcomes (1)

  • To compare the occurrence of AF (>350 bpm) during a period when AF pacing therapies are programmed on (APP and VRR) and during when AF therapies are programmed off.

    one year

Secondary Outcomes (1)

  • To compare AF burden between patients with AF therapies programmed on (APP and VRR) and patients with AF pacing therapies turned off (APP and VRR). Burden is defined as the product of the number of AF events and duration of events. To compare the time to

    one year

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • No prior history of AF or atrial flutter, primary indication of SSS or AV block for dual chamber pacemaker, confidentiality agreement signed and dated before implant, available for follow-up at the study centre where they were enrolled at the protocol defined intervals, willing and capable of participating in all testing associated with the study, on stable regime of arrhythmia management drugs.

You may not qualify if:

  • Documented history of AF or atrial flutter, clinically significant ventricular arrhythmias, \< 18 yrs old, life expectancy \< 1 year or expectation of heart transplantation during the study period, likely to or have received a mechanical tricuspid valve during the study, enrolled in other cardiovascular studies, women who are pregnant, inability or refusal to sign Patient Confidentiality Agreement, inability or refusal to complete the follow-up schedule at the study centre in which they were enrolled, exhibit arrhythmias due to reversible cause eg, digitalis toxicity, hypoxia, transient electrolyte imbalance, acute myocardial infarction or electrocution.
