The AliveCor Kardia Mobile is a hand-held device which records a single heart trace when both thumbs are placed on the sensor pads. When an app is downloaded to a mobile phone, the trace can be viewed on the screen. Irregular heart beats can be seen, enabling patients with Atrial Fibrillation to be identified.

You might see healthcare assistants using the AliveCor as a preliminary screening tool to detect the 2-3% of patients with undiagnosed AF, enabling them to receive treatment before they suffer a devastating stroke.

The video below shows how it works.
