The health support of everybody should be considered as a highly significant, due to the huge increases in various health concerns. Meanwhile, heart attacks and cardiovascular disorders caused a public issue with high mortality ratios and cardiac patients, thereby increasing the open-heart surgery cases, limiting the available number of doctors, and most importantly generating an inefficient environment for caring patients, particularly with severe and fragile health problems. Hence, healthcare systems have begun to connect with IoT to keep each patient's digital identification. We, therefore, aimed at designing a smart device for cardiac patient's monitoring to save time and effort for both caregivers and patients. Our design also could prevent crowding in health care places, provide a link between a person's hectic lifestyle and regular, and continuous the health checkups via remote access. The results from our prototype device can be employed for cardiac patient monitoring using IoT-technique which will monitor several health signs, i.e., blood oxygen ratios, heart rate, and body temperature. These signs can be remotely retrieved and/or imagined via medical experts on a handheld device through blynk APP from any location at any time. They also can gather the data and provide the real-time information about the patient through the Bluetooth module. Several individuals were put through a series of tests based on a variety of parameters. In conclusion, IoT could be recommended as a smart tool in the health care for monitoring the cardiac patients quickly and efficiently.
