Abstract
A cardiac signal transmitter unit adapted for use by the pacemaker patient which detects and processes electrocardiogram and pacemaker information, and which generates a corresponding audible signal for transmission to a remote location for reception and analysis. The unit employs a three input electrode array for developing a differential signal, has separate channels for processing the electrocardiogram data and the pacemaker data, and includes a fail-safe battery monitor circuit for completely disabling the unit as the battery nears the end of its useful life.
