A portable belt-type monitor of body functions such as the heart and breathing is described formed of a plurality of articulated, distributed modules containing EKG sensors, a respiration sensor, circuitry including a microprocessor for sensing alarm conditions, a transmitter for sending alarm conditions to a remote receiver and a battery to drive the various circuits. A respiration sensor is described wherein tension changes in the belt due to breathing are transformed into opposing forces directed transversely to the belt and which cooperate to produce a reliable, sensitive detection of respiratory activities. The belt can be conveniently worn with reliable EKG sensing during normal body activities. A processor program is described whereby these body functions are monitored with alarms being generated when these functions exceed preset limits while preserving sufficient functional performance data when an alarm occurs.
