ABSTRACT:
A method for judging irregular heartbeat performs a measurement step to measure a plurality of heartbeat pulses within a time period for a user, and to measure inter-pulse durations and total pulse numbers. The method further performs a calculation step to calculate an averaged inter-pulse duration and a heartbeat number. Afterward, the method performs a first-stage judgment step to judge whether the measured pulse number is sufficient. When the first-stage judgment step is matched, a second-stage judgment step is performed. The second-stage judgment step judges irregular heartbeat condition by comparing the averaged inter-pulse duration with each inter-pulse duration. Finally, this method performs a display step to show a sign of irregular heartbeat when the irregular heartbeat condition is matched. This method can solve inaccuracy problem due to preset threshold.
