Intraoperative Testing of the Implantable Cardioverter‐Defibrillator: How Much Is Enough?

Abstract

In this select patient cohort, success of ICD therapies and sudden-death-free survival were similar in patients who had DFT, safety margin testing, and no testing, but overall survival was significantly lower in the no-testing group. Thus in the absence of prospective mortality data, a minimum of safety margin ICD testing should remain standard practice.
