Patent ID: 7460902

Claim:
A method for monitoring atrial activation in an individual patient, the method comprising the steps of: receiving ECG signal data obtained from a patient; based on a first sequence of P waves received in the EGG signal data, predicting a moment of occurrence for a subsequent P wave in the ECG signal data; estimating a reference wave form for the subsequent P wave based on a second sequence of P waves received in the ECG signal data; checking whether said subsequent P wave occurs in the ECG signal data within a first time window around the predicted moment of occurrence; monitoring whether a subsequent QRS complex occurs in the ECG signal data within a second time window ending after the first time window; and indicating the detection of an AV block if the subsequent QRS complex fails to occur in the ECG data within the second time window, wherein the monitoring step is performed upon detecting in the checking step that said subsequent P wave occurred in the ECG signal data within the first time window.
