Abstract
Method and apparatus for arrhythmia analysis of Holter-type ECG recordings including a tape playback unit having an analog signal output of successive ECG complexes or heart beats, a converter for generating data composites representing each complex, a computer for making and storing data templates in bins corresponding to operator classification of complexes as normal, supraventricular ectopic (SVE), ventricular ectopic (VE), or unknown, for comparing successive composites with stored templates and conditions to determine a match condition, and for signaling a corresponding event to an event counter and display. In learn mode the computer signals the tape playback to stop and to display an unmatched complex for operator classification and possible subsequent generation of a new template, after which scanning is resumed.
