Abstract

Three electrodes are placed on the patient's chest wall. These electrodes are connected to an amplifier circuit which feeds a circuit connected to the display showing the heart stream curve and also to a digital pulsate display. This circuit consists in the main of a frequency and voltage dependent voltage transformer at its input so that only the required signal is allowed through. The display device consists of a square screened c.r.t. with a quick heating cathode, which enables an oscillogram to be shown after 0.55 secs after switching on. The digital display shows the pulse rate by counting the teeth in the oscillogram without the need for a calculating scale.
