Abstract
A computerised system for the 3-dimensional dynamic display of joint interval histogram (j.i.h.) of heart beats was developed. It presents a dynamic histogram of a programmable number of beats on an oscilloscope screen. The 3-dimensional display of the j.i.h. was found to be characteristic of rate and rhythm disturbances. The system facilitates the monitoring of transient arrhythmias. It can serve for the detection and quantisation of ventricular and supraventricular extrasystoles, rate changes and statistical evaluation of atrial fibrillation. The system was used in the Intensive Coronary Care Unit and is suggested as a useful tool in cardiac patient monitoring in addition to real-time e.c.g. display.
