Key result
A newly designed microcontroller-based heart beat monitoring system showed no significant difference in beat rate measurements compared to a pulse oximeter and digital arm cuff (P=0.519049).
Why the study?
Technical action was needed to alleviate the severity of cardiovascular disease resulting from high blood pressure amid declining healthcare infrastructure in Nigeria.
Does a newly developed microcontroller-based Heart Beat Monitoring System provide comparable heart rate measurements to standard devices (Pulse Oximeter and Digital Arm Cuff)?

p-value: p=0.519049
A newly designed, cost-effective microcontroller-based heart beat monitoring system provides heart rate measurements comparable to standard pulse oximeters and digital arm cuffs.
Oyediji et al. (2021) studied High Blood Pressure. Microcontroller based Heart Beat Monitoring System vs. Pulse Oximeter and Digital Arm Cuff was evaluated on Beat rate (BPM) difference among devices (p=0.519049). A newly designed microcontroller-based heart beat monitoring system showed no significant difference in beat rate measurements compared to a pulse oximeter and digital arm cuff (P=0.519049).
