Utility of smart watch in expediting diagnosis of cold drink-triggered atrial fibrillation: a case report

The case illustrates the valuable contribution of smart watch technology in the diagnostic evaluation of patients with short-lived palpitations. The case also educates clinicians about cold drink and food as a trigger of paroxysmal atrial fibrillation. This trigger, like alcohol, can be modified. Cold drink trigger avoidance has been reported by patients to reduce atrial fibrillation recurrence and is a low-risk, cost-effective strategy that is often successful.
