Temporal changes in device-derived daily activity related to ventricular arrhythmias from the CERTITUDE registry.

ABSTRACT:

Background

There have been limited data examining the temporal relationship between device-derived daily activity and ventricular arrhythmias (VAs).

Objective

We aimed to assess whether activity predicted VAs or VAs predicted changes in activity.

Methods

The CERTITUDE registry includes over 55,000 implanted devices active on Home Monitoring. Daily data on activity are captured by a 1-axis accelerometer. Temporal changes in activity during treated VAs were analyzed using the first event and 7-day activity windows (baseline, pre-event, and postevent). Baseline period was defined as 31 to 38 days prior to VA. VAs were categorized by heart rate (≤200 beats/min, >200 beats/min) and treatment (shock or antitachycardia pacing). Differences were assessed using the binomial pr
