Heart rate is a very vital health parameter that is directly related to the soundness of the human cardiovascular system. But high blood pressure, high cholesterol level or diabetes mellitus can lead to blockade of coronary arteries and result into heart palpitation, in other words, missing heart beats. Frequent of these heart palpitations lead to heart attack. Timely updates can save a potential victim of heart attack. This paper describes a technique of a developed mobile device that can monitor heart rate, detect missing heart beats due to premature ventricular contractions (PVCs) and send the heart rate and missing beat information via website to a remote person or physician. Heart rate is measured through a pulse sensor and microcontroller which is based on the photoplethysmography (PPG) process. The device continues to take real time values after placing heart rate sensor on fingertip, ear lobe or wrist enabling anyone to monitor his/her heart rate on the move.
