Join TTAC as we review The KardiaMobile 6L. This is the most recent device from AliveCor Kardia. The KardiaMobile 6L features a more advanced 6-lead Electrocardiogram (EKG) instead of the single-lead EKG from their previous products. The 6-lead EKG can provide more detail as opposed to the single-lead EKG. The device is single purposed and does not provide any additional functions beyond the EKG exam.
