Key result
ICD and CRT-D battery longevity varies widely across geographic regions, highlighting differences in practice patterns.
Why the study?
Although battery longevity of ICDs and CRT-Ds affects clinical outcomes and resource use, the contribution of regional practice patterns to battery consumption remained poorly characterized.
Demonstrates regional practice variations in cardioverter-defibrillator battery consumption, highlighting the need to optimize device longevity and resource utilization.
Battery longevity of implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) affects clinical outcomes and resource use, yet the contribution of regional practice patterns to battery consumption remains poorly characterized.
