Claim 17:
18. A computer implemented method of assessing the likelihood of response to cardiac resynchronization therapy (CRT) for a patient, the method comprising:
receiving, by a processing unit, time-domain ECG data obtained from the patient;
analyzing, by the processing unit, the time-domain ECG data to detect abnormal QRS peaks using a sliding window;
determining, by the processing unit, a QRS peak (QRSp) score by quantifying the abnormal QRS peaks in the sliding window of the time-domain ECG data;
determining, by the processing unit, a measure of likelihood of CRT response for the patient based on the QRSp score;
assigning a CRT peak threshold based on a number of abnormal QRS peaks;
comparing the QRSp score to the CRT peak threshold; and
indicating that the patient is a candidate for CRT if the QRSp score is greater than the CRT peak threshold,, wherein the measure of likelihood of CRT response is used to identify candidates likely to respond to CRT; and a treatment regimen for the patient is determined in response to the indication that the patient is a candidate for CR, wherein the treatment regime includes performing CRT on the patient.
