Defibrillation thresholds appear stable in this cohort; supports initial testing reliability but leaves open need for retesting at replacement.
Does the internal cardiac defibrillation threshold remain stable over time in patients with an automatic implantable cardioverter-defibrillator?
Internal cardiac defibrillation thresholds remain stable over time, suggesting that initial effectiveness testing is a reliable indicator of long-term device efficacy.
