Key result
Tailored ICD programming, including prolonged detection times and higher rate cutoffs, decreases inappropriate therapies and mortality in primary prevention populations.
Why the study?
Does tailored ICD programming reduce inappropriate therapies and mortality in a primary prevention population?
Does tailored ICD programming reduce inappropriate therapies and mortality in a primary prevention population?
Tailored ICD programming, including prolonged detection times and higher rate cutoffs, effectively reduces inappropriate shocks and mortality in primary prevention patients.
May support tailored ICD programming in primary prevention; leaves open need for confirmatory RCTs on mortality.
Optimal programming of implantable cardioverter defibrillators (ICDs) is essential to appropriately treat ventricular tachyarrhythmias and to avoid unnecessary and inappropriate shocks. There have been a series of large clinical trials evaluating tailored programming of ICDs. We reviewed the clinical trials evaluating ICD therapies and detection, and the consensus statement on ICD programming. In doing so, we found that prolonged ICD detection times, higher rate cutoffs, and antitachycardia pacing (ATP) programming decreases inappropriate and painful therapies in a primary prevention population. The use of supraventricular tachyarrhythmia discriminators can also decrease inappropriate shocks. Tailored ICD programming using the knowledge gained from recent ICD trials can decrease inappropriate and unnecessary ICD therapies and decrease mortality.
