An 18-year-old male with arrhythmogenic cardiomyopathy was referred for catheter ablation of ventricular tachycardia after experiencing appropriate implantable cardioverter-defibrillator (ICD) shock. Six months prior, he had undergone uncomplicated implantation of an extravascular ICD (EV-ICD) [1].

Because athletes young and old can suffer cardiac arrest, some states have mandated the placement of automated external defibrillators (AEDs) in gyms, stadiums and other sports venues. But a new study finds the use of AEDs by bystanders for cardiac arrest at athletic sites didn't improve much after states enacted these laws.
