This is a case report of a 45-year-old man who reported complete amnesia during the very first kilometer of a 10-km run. He was wearing a heart rate monitor (HRM). The interrogation of his HRM watch showed 200 bpm tachycardia beginning in the first kilometer and increasing up to 220 bpm during the last kilometer. The patient was asked to wear a Holter-monitor (Holter Research Laboratory; Helena, Montana USA) electrocardiogram (ECG) while practicing a training session. This examination allowed for the diagnosis of an adrenergic paroxysmal atrial fibrillation (AF) with an impressive auriculo-ventricular conduction over 260 bpm. This case highlights that non-medical devices, such as connected watches, can be helpful to diagnose arrhythmias.
