Summary
Implanted cardioverter defibrillators (ICDs) significantly impact patient quality of life. While shocks are uncomfortable, most patients tolerate them due to the life-saving benefits of the ICD device.
Area of Science:
- Cardiology
- Medical Devices
- Patient Psychology
Background:
- Implanted cardioverter defibrillators (ICDs) improve patient survival but affect quality of life.
- Understanding patient experiences with ICDs is crucial for effective management.
Purpose of the Study:
- To assess the physical, social, and psychological impact of ICD shocks and the device itself.
- To understand patient responses to ICD therapy.
Main Methods:
- Retrospective survey and concurrent interviews with 119 ICD patients.
- Assessed patient perceptions of shock severity, emotional responses, and behavioral actions post-shock.
Main Results:
- Most patients found ICD shocks uncomfortable (79% rated 3-5/5) but tolerated them as life-saving.
- Responses varied: 50% contacted physicians, 30% sought emergency care, 65% had no warning signs.
- Patient interest in pre-shock warnings was divided (54% wanted warnings, 31% did not).
Conclusions:
- ICD shocks are perceived as moderately uncomfortable but are accepted for their life-saving function.
- Patient management strategies should consider the varied psychological and behavioral responses to ICD therapy.
