An intelligent cardiac auscultation is the process of monitoring the heart beat signals variations of a patient monitoring system for monitoring the patients health condition automatically through sensors based connected networks in Internet of Things (IoT). It detects the critical condition of a patient by processing sensors data and instantly provides push notification to doctors. There is no process of monitoring of a particular cardiac disease which can lead to loss of life due to improper checkups and not following the lifestyle proposed by the doctor. In our proposed system, coronary heart disease monitoring based on wireless sensors are used to monitor cardiac patient for 24/7 without any human intervention using piezoelectric sensors which is used to measure artery thickness by the flow of blood vessels and extract the waveform. The waveform is classified into normal and abnormal waveform. These abnormal waveform is sent to mobile application where it receives the data and plots the signal curves in real-time. The mobile application acts as the display device and has the capability to upload data to a cloud platform for further analysis and an intimation is sent to the cardiologist. The authorized Cardiologist can get access to the cloud platform to get the dataset and results via any peripheral devices which are equipped with specific software and diagnose the results.
