A 59-year-old man with ischemic cardiomyopathy had a single-chamber Medtronic Entrust™ ICD and Sprint Fidelis™ Model 6949 dual-coil true bipolar lead implanted over 2 years ago after out-of-hospital VF. His NYHA Class is III and left ventricular ejection fraction is 34%. After an episode of monomorphic VT storm a year ago, he has been treated with amiodarone 200 mg per day to decrease the frequency of VT. He now presents for a routine follow-up visit. The pacing threshold is 0.5 V at 0.4 ms, and the pacing lead impedance is stable at 560 Ω. One episode of device-detected VT is stored in the ICD. Diagnosis and management steps are discussed.
