A Phono-Electro-Cardiogram Monitoring Unit that detects and monitors ECG and PCG signal comprising a phono-electro-cardiogram sensor button capable of electrical conduction of the electrical potential changes arising from the heart activity of a user or a patient. The sensor button includes a microphone which allows detection of electrocardiography signal and phonocardiogram signal simultaneously and the detected electrocardiography signal and phonocardiogram signal are processed by a multifunction microprocessor and the processed electrocardiography signal and phonocardiogram signal data are stored in a memory or be transmitted to a work station or a personal cloud for further processing and storing where the data can be forwarded to authorized individuals via wireless connectivity for communication, interpretation, service and help.
