Palpitations are one of the most common conditions referred to cardiologists. It accounts for approximately 16% of outpatient visits. Common causes of palpitation include arrhythmias, psychiatric disease, medications and metabolic disorders.

One of the methods currently used to conduct initial investigation for palpitation is an ambulatory monitor, known as a holter monitor. The holter monitor offers 48 hours of continuous monitoring with patients keeping a diary of symptoms. The major limitation of this type of monitoring is the short duration of monitoring, particularly in patients with infrequent symptoms.

This project will investigate the use of Kardia – a clinically validated medical grade smart phone based electrocardiogram device compared to a holter monitor.

Kardia is compatible with both Android and Apple devices and allows cardiac rhythm to be stored and relayed to a medical practitioner for analysis. Patients would be allowed to keep this device for an indefinite period and use when symptoms develop. It could improve the diagnostic yield in those patients with rare events and be particularly useful for patients in rural and remote areas. To date, the use of mobile health tools in the detection and diagnosis of palpitation has not previously been evaluated.
