A wrist watch size heart rate monitor coupled with a flexible metal expansion band detects a electrocardiac signal on one arm and applies that detected signal to electronic circuitry within the monitor. Means are also included for receiving a second electrocardiac signal from the other arm to obtain an electrocardiac lead I signal. The receiving means may be a contact member adapted to being placed in physical contact with a second flexible metal expansion band around the wrist of the other arm and having a like contact member associated therewith or the receiving means may be metal members adapted to having the thumb and a finger of the hand of the other arm squeezed thereagainst.
