Cardiac Transplantation for Refractory Catecholaminergic Polymorphic Ventricular Tachycardia

Figures

• 

  Figure 1. Ventricular Fibrillation Refractory to Maximal ICD Discharges This figure shows the implantable cardioverter defibrillator (ICD) interrogation from this patient showing persistent ventricular tachycardia refractory to defibrillation. Ultimately, 93 s after onset of the patient’s final episode of ventricular fibrillation (VF), the ICD exhausted all therapies. AS = atrial sensing; F = fibrillation; HV = high-voltage therapy; VS = ventricular sensing.

  Figure 2. Spontaneous Conversion of Refractory CPVT This figure shows that after approximately 142 s of refractory ventricular fibrillation, this final episode of arrhythmia spontaneously converted to normal sinus rhythm. AS = atrial sensing; CPVT = catecholaminergic polymorphic ventricular tachycardia; VS = ventricular sensing.
