Substantial PWA variation during daily activities occurs regardless of pacing mode; hypothesis-generating for adjusted atrial sensing thresholds in pacemaker patients.
Does single pass lead VDD/R pacing compared to DDDR pacing affect P wave amplitude stability during daily life activities in pacemaker patients?
Large variations in P wave amplitude occur during daily activities regardless of pacemaker type, suggesting that a standard twice sensing threshold may be insufficient to ensure adequate atrial sensing.
