ABSTRACT:
Apparatus for recognizing cardiac arrhythmias digitalises analog signals which are obtained when carrying out sensing at the heart or on the body and carries out a first differentiation of the digitalised signals. A gradient pattern detector compares the differentiated signals thereby produced with normal differentiated signals detected during sinus rhythm as to amplitude, polarity and sequence. Differences between the differentiated signals will be indicative of pathological tachycardias, the nature of which will be identified by comparison with pre-programmed signals of like type and a response to terminate the arrhythmia can be delivered to the heart.
