ABSTRACT:
A portable alarm apparatus for use by a sudden heart attack patient is provided that is characterized by a housing part connected to a suspension member for hanging around a patient's neck. Sensors are disposed on the suspension member and connected to an extending lead, enabling the sensors to contact respective pulse spots on the patient's neck, due to the downward force resulting from gravity acting on the housing part. The sensors detect the pulse signals in an artery in the user's neck corresponding to heartbeats and output an electrical signal for input to a control circuit disposed in the housing part for storage, display and generation of a warning alarm.
