Why the study?

Does a tiered-therapy, multiprogrammable antiarrhythmia device improve clinical outcomes and reduce the need for antiarrhythmic drugs and additional devices in cardiac arrest survivors?

Key Points

This report describes initial experience with a multiprogrammable antiarrhythmia device designed for cardiac arrest patients.
50 cardiac arrest survivors were implanted with a multiprogrammable antiarrhythmia device.
Epicardial lead system used in 35 patients; transvenous lead system in 15 patients.
Follow-up data collected over a mean period of 15 +/- 5 months.
Total patient survival was 96%, with no deaths from arrhythmias or cardiac causes.
18% of patients avoided bradycardia pacemaker use due to backup pacing features.
82% of patients eliminated the need for antiarrhythmic drugs due to device capabilities.

Structured PICO

Does a tiered-therapy, multiprogrammable antiarrhythmia device improve clinical outcomes and reduce the need for antiarrhythmic drugs and additional devices in cardiac arrest survivors?

Population

50 cardiac arrest survivors with an index arrhythmia of ventricular fibrillation (n=23), ventricular tachycardia (n=21), or both (n=6).

Intervention

Tiered-therapy, variable detection criteria, multiprogrammable antiarrhythmia device capable of antitachycardia pacing, cardioversion, and defibrillation (epicardial lead system in 35 patients, transvenous lead system in 15 patients).

Outcome

Total patient survival and clinical benefits including avoidance of bradycardia pacemaker, prevention of inappropriate shocks, elimination of antiarrhythmic drugs, and ability to perform noninvasive programmed electrical stimulation.hard clinical

A multiprogrammable antiarrhythmia device provides substantial clinical benefits for cardiac arrest survivors by reducing painful shocks, antiarrhythmic drug use, and the need for additional devices.

Discussion

Implication

Provides preliminary support for multiprogrammable devices in arrest survivors; leaves open need for randomized confirmation before adoption.
