A portable instrument is described which quickly indicates the presence or absence of myocardial activity. The instrument consists of two probes connected by a flexible retractible coiled cable. The stainless steel tips of each probe constitute the input connections of the enclosed circuitry and, in use, are placed in contact with the skin on the precordium. The electrical signal present between probe tips is processed by a network of filter, trigger, and logic circuits, the result of which is a bright flash of a light-emitting diode for each ORS complex present at the input. Because of its simplicity of operation, this device could easily be used by paramedical personnel as well as physicians in a variety of emergency situations. Author
