Implication
Phrenic stimulation poses ongoing management challenges in CRT; observational data leaves open optimal lead and programming strategies.
Structured PICO
What is the prevalence and clinical impact of phrenic stimulation in patients receiving cardiac resynchronization therapy devices?
P
Population
197 consecutive patients who received a cardiac resynchronization therapy (CRT) device between 2003 and 2006.
I
Intervention
Cardiac resynchronization therapy (CRT) device implantation with assessment of phrenic stimulation and LV threshold.
O
Outcome
Prevalence of phrenic stimulation (PS) and its clinical relevance.safety
Phrenic stimulation is a common and clinically relevant complication of CRT that can be mitigated by using bipolar LV leads and cathode programmability.
