Why the study?
Does posture and dipole location affect the atrial signal amplitude of a floating VDD pacing electrode in pacemaker patients?
Does posture and dipole location affect the atrial signal amplitude of a floating VDD pacing electrode in pacemaker patients?
Atrial signal amplitude in single-lead VDD pacemakers varies extensively with posture and time, necessitating high sensitivity programming to prevent atrial undersensing.
No takes yet. Share an insight, caveat, or question.
Atrial sensing variability may raise undersensing risk in VDD devices; leaves open optimal programming and lead designs for long-term reliability.
SUN et al. (1998) studied this question.
