Abstract
A device for measuring heartbeat rate that includes a device casing or wrist strap with skin contact electrodes, and a coil receiver for receiving telemetrically transmitted heartbeat signals for displaying heartbeat data either from the receiver, or the skin contact electrodes. The signals from the skin sensor are filtered, and subjected to an AGC device and pulse shaper. The received signals are amplified. A microcomputer, memory, and display are common to both the pulse shaped detected heartbeat signal and the amplified signal received from the transmitter.
