Key Clinical MessageTakotsubo syndrome is classically characterized by apical ballooning and left ventricle akinesis associated with an underlying catecholamine surge. In patients with suspected Takotsubo syndrome, clinicians should be vigilant for acute coronary syndrome and arrhythmias. Ventricular standstill with underlying Takotsubo syndrome should be managed with a dual‐chambered pacemaker to improve patient outcome.

Key Clinical MessageBelhassen tachycardia is the most common idiopathic ventricular tachycardia arising from the left ventricle, classically characterized by a right bundle branch block and left axis deviation. Vigilance for Belhassen tachycardia is essential as intravenous verapamil has proven to be highly efficacious for treating symptomatic patients with this underlying arrhythmia.
