... ondition of the patient. Communicating the information to the doctor and giving the exact diagnosis to the patient through the IOT is a challenging task. This paper gives a comparative study on health monitoring and detection of the patient. ECG monitoring system in the form of mobile, wireless and remote technologies are reviewed in this paper. Further objective of this paper is to identify the research gaps in existing systems and finalise the research statement for further work.
