The impact of digital health innovations on healthcare is rapidly accelerating. In particular, wearable devices for ambulatory cardiac monitoring are gaining increasing popularity among the general population. A 45-year-old physically active male presented to a cardiology clinic following an episode of palpitations and dizziness, which occurred after a 24-hour work shift. Shortly after symptom onset, he used his Apple Watch to perform an electrocardiogram, which detected monomorphic ventricular tachycardia, followed by sinus rhythm and a premature atrial extrasystole. Despite further extensive testing, no clear cause of ventricular tachycardia was identified. This case highlights the growing role of wearable devices, such as smartwatches, in cardiac monitoring and their ability to detect significant arrhythmias in asymptomatic individuals. However, it also raises questions regarding the extent of diagnostic testing required for such findings, particularly in cases of selflimiting arrhythmias.
