Finger ECG (AliveCor) is an one-lead ECG recording device, which can monitor patients’ heart rhythm through a smartphone or tablet computer when they have symptoms. This device is approved by the US Food and Drug Administration. The recording process is very simple and it takes only 30 seconds.

This device is useful to differentiate whether the patient is having a normal heart rhythm or atrial fibrillation which is the commonest heart rhythm problem leading to a fatal stroke
