Abstract
A method and improved apparatus for automatically locating the QRS portion of an electrocardiographic signal and for generating a corresponding synchronization pulse is disclosed. Properties associated with the QRS portion of an electrocardiographic signal are utilized in the implementation of an adaptive peak detector capable of accurately operating with electrocardiographic signals varying in amplitude or polarity. The adaptive peak detector is also capable of discriminating against signal components lying outside certain predetermined limits.
