Abstract
Over the years, the decline of Nigeria’s health-care infrastructure has become alarming. The 2018 annual report of WHO shows that 75% human cardiovascular disease resulted from High Blood pressure. Immediate technical action is needed to alleviate the severity to the barest minimum. This research work presents a designs and implementation of microcontroller based Heart Beat Monitoring System for High Blood Pressure Patients. The developed system consists of three sections which include; Input section consisting of Heart beat sensor that senses and converts the blood pulse from a fingertip into an electrical signal. The sensor thereafter sends the signal into microcontroller, which is the control section that acts and communicates the result through LCD and output section. The displayed results show the beat rate in unit of beat per minute (BPM). The developed system was evaluated and demonstrated with two other standard devices namely: Pulse Oximeter and Digital Arm Cuff using a one-way analysis of variance (ANOVA) to determine its level of significance. The P Value of 0.519049 was found significant at 0.05 level of significance. Additionally, the results indicate that there is no significant difference among the three devices. It was concluded the designed device is more cost effective, user friendly and easily assembled due availability of needed materials in contrast with the other standard devices.
