A man in his 40s with self-reported hypertrophic cardiomyopathy, hypertension, and obstructive sleep apnea presented in cardiac arrest owing to ventricular tachycardia/fibrillation. He reported feeling unwell on the afternoon of presentation with dizziness and blurry vision, and then abruptly lost consciousness with seizure-like activity. On the arrival of emergency services, he was found to be pulseless with a rhythm of ventricular fibrillation; he was resuscitated with return of spontaneous circulation, intubated, and brought to the emergency department where cooling was initiated. His initial electrocardiogram (ECG) is shown in the Figure, A.
