ARMY HEART MONITOR -- MODEL IV,

Abstract

Model IV of the Army Heart Monitor is an electronic device that monitors the electrocardiogram (ECG); sounds an alarm on diagnosing a high or low heart rate, excess electrical noise, cardiac arrest, or ventricular fibrillation; and displays the diagnosis on a meter. Ventricular fibrillation is sensed on the basis of five parameters related to the shape and rate of occurrence of the ECG signals. A noise discrimination system using several frequency and pulse-width criteria allows accurate determination of heart rate when the ECG signal is accompanied by high levels of electrical noise. The monitor will function for long periods on self-contained batteries and will operate in the military temperature range. Because it operates automatically (analysis of an ECG by trained personnel is unnecessary), it may be used in situations where oscilloscopes and paper writers are not available or where their use is not feasible.
