Study checks if testing heart devices during replacement is worthwhile
NCT ID NCT04206371
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study followed 143 people who had a defibrillator (ICD) replaced to see if testing the device's ability to deliver a shock is safe and useful. The test involves briefly inducing a fast heart rhythm under anesthesia. The goal was to check for device problems, like abnormal shock impedance, that might need fixing. The study did not test a new treatment but aimed to improve how doctors manage ICD replacements.
