The DigiTrak XT digital Holter monitor is the size of an AT&T pager, runs on a single AAA battery and can tolerate complete water submersion (survives 15 seconds in 2 feet of water, the depth of a bathtub).

The DigiTrak XT Monitor’s LCD screen allows you to check the quality of the electrode connection on all 3 leads without connecting to a cardiograph or other device. Every DigiTrak XT Monitor has adjustable pacemaker detection included as well.
