Title: DEVICE FOR DETECTING HEART RHYTHM ANOMALY
Abstract:
A device for detecting a heart rhythm anomaly. A processor of the device performs the following steps: a, continuously measuring pulses in a time range, so as to obtain pulse sequences and pulse time interval sequences corresponding to the pulse sequences; and b, computing an absolute value of a difference between a single pulse time interval in the pulse time interval sequences and an average of the pulse time interval sequences, and determining that an abnormal pulse exists when the absolute value is greater than or equal to 15% to 25% of the average of the pulse time interval sequences. The device for detecting a heart rhythm anomaly can noninvasively detect irregular pulse peaks, irregular heartbeats, atrial fibrillation, sick sinus syndrome and other anomalies, and can be used in sphygmomanometers or wearable devices to help users perform detection by themselves.
