Patent Images
1. A cardiac analyzer comprising:
- first and second input means for receiving input signals from separate sources;
means for detecting peaks in the input signals of both input means;
means for classifying detected peaks for both input means;
means for providing classification pairs, one from each input means at a corresponding time;
means for analyzing said detected peak pairs and said peak pair classification; and
means for identifying which peaks are QRS complexes.

Abstract
An ambulatory cardiac analyzer and recorder includes an allocation and priority scheme which has quotas for classes of QRS events and priority between types of events within a class. The quality of a low priority event is used to replace a similar type of event when the memory is full. The peak detection, QRS identification and classification circuit process and correlate information from both of two input channels. This allows quicker and more accurate determination of QRS waveforms as well as typical QRS waveforms.
