A Simple Approach to Detect and Count Missing Cardiac Pulses and PPG Based Heart Rate Sensing

In reference to general mathematics, Pulse is mainly a rapid, momentary change in the amplitude of any signal from a value of baseline to a higher or lower value, followed by a swift return to the baseline value. In the context of medical science, pulses (heart-pulse) are very useful for diagnosing a patient suffering from cardiac anomalies such as arrhythmia, in which the patient suffers from irregular heartbeat when some of the pulses in his cardiac pulse chain are failed to occur which have a predefined interval of time. Hence, the prototype is to be designed such that any such skipped beats do not go undetected. Therefore, in this paper, a novel, simple solution technique is proposed, in which a condition is simulated where one or more pulse would go missing, a process named Missing Pulse Generation, after which, detection of the missing pulses and their counting after a certain time, have been executed, and along with an external PPG (Photoplethysmogram) based Pulse sensing mechanism has been used to measure patient’s heart beats per minute (BPM) physically, so that, a specialist can prescribe a suitable solution for the patient’s recovery. In heart rate monitoring system, conventional missing pulse detection technique has been used since long time by which only the presence of unnatural missing pulses can be detected but here our approach is more effective than the conventional one as the detection & counting of missing & extra cardiac pulses have been brought together from human cardiac pulse chain and heart rate sensing mechanism in an automated & accurate way by minimizing the diagnosis time which is very much useful for long continuous heart-rate monitoring.
