Why the study?

What is the incidence and cause of inappropriate ICD interventions in patients with an implantable defibrillator?

Population

214 consecutive patients undergoing implantable defibrillator (ICD) implantation

Design

Cohort

Follow-up

median 2.7 years (3.7 years IQR)

Authors

TSThomas StüberKlinikum Itzehoe

Discussion

Member takes

Implication

Inappropriate ICD interventions remain frequent in practice; observational data leaves open optimal prevention strategies.

Key Points

This study aims to determine the incidence and causes of inappropriate interventions in patients with an implantable defibrillator.
Observational longitudinal study conducted at the University Hospital of Berne
Patients undergoing ICD implantation were included in a registry
Electrograms of triggering episodes were reviewed to classify ICD interventions as appropriate or inappropriate.
214 patients followed for a median of 2.7 years; 81 inappropriate interventions occurred in 58 patients (27%)
Common triggers of inappropriate interventions included atrial fibrillation (44%) and sinus tachycardia (32%)
Sustained ventricular tachycardia identified as a risk factor for inappropriate interventions.

Structured PICO

What is the incidence and cause of inappropriate ICD interventions in patients with an implantable defibrillator?

Population

214 consecutive patients undergoing implantable defibrillator (ICD) implantation

Intervention

Implantable defibrillator (ICD)

Outcome

Incidence and causes of inappropriate ICD interventions, and identification of patients at risksafety

A significant proportion (27%) of ICD patients experience inappropriate interventions, primarily driven by supraventricular arrhythmias, with prior sustained VT being a key risk factor.
