Abstract
The detection of a heart response in an ECG signal of a patient having a pacemaker emitting a pace pulse. An area of a pulse of the ECG signal comprising a pace pulse tail of the pace pulse is first determined and an estimated mathematical function is derived from the determined area. The estimated mathematical function and the ECG signal are evaluated together in order to distinguish the heart response in the ECG signal.
Claims12
A system for detecting a heart response in an ECG signal of a patient, the patient having a pacemaker emitting a pace pulse, the system comprising:
- means for measuring an ECG signal of said patient in response to an applied pace pulse having a main pulse and a tail component, said ECG signal also having a main pulse and a tail component,
- means for determining an area of the tail component of the ECG signal,
- means for determining an estimated mathematical function describing a characteristic of at least a portion of the tail component of the ECG signal from the determined area of the tail component, and
- means for detecting the heart response by evaluating the estimated mathematical function together with the ECG signal.
