Real time QRS duration measurement in electrocardiogram

摘要

ECG data may be processed in a mobile device by receiving a stream of filtered ECG data samples comprising PQRST pattern cycles. An R point (451) of a PQRST pattern in the filtered ECG data is determined. A portion of samples (510) is selected from the filtered ECG data surrounding the R point. QRS duration of the PQRST pattern is then determined by processing ( Fig 5 ) the selected portion of samples using an application program executed by the mobile device.
