Polymorphic Ventricular Tachycardia Detected by a Smartwatch in a Patient With Recurrent Syncope.

The diagnosis of vasospastic angina remains challenging. It may present with syncope and life-threatening arrhythmia. Patients with syncope usually require automatic modes of recording. We describe a patient with recurrent syncope and polymorphic ventricular tachycardia documented by a smartwatch. Eventually, the arrhythmia was attributed to vasospasm and effectively managed with pharmacotherapy.
