Have you seen TV ads for the AliveCor KardiaMobile 6-Lead Personal EKG Monitor? These commercials feature someone asking folks on the street whether their heart is healthy.

The KardiaMobile 6-Lead Personal EKG Monitor is a pocket-sized lifesaver that delivers medical-grade heart readings in just 30 seconds. No wires, no mess — just fast, easy-to-read results.

That said, I do have that Kardia Mobile. It was approved by my doctor for monitoring Afib, it seems to work fine, but you do need a phone or tablet to make it work.
