摘要：AbstractThe cardiovascular diseases take around 17,9 million of lives world widely each year [1]. The first examination in the cariology department and the famous medical device is the Electrocardiograph (ECG), the ECG gives an idea about the heart physiology because it is an electrical signal that represents the electrical activity of the heart system, and via that signal the cardiologist can observe too many parameters, such as the heart rate, the mechanical contraction of the heart muscles etc. In fact, the heart rate or the heart beating area is included in a medical specialty called rhythmology. That field of study deals mainly with the heart rate troubles or arrythmias. Actually, there are several arrythmias but in this paper we will mention only about bradycardia and tachycardia that correspond respectively to the slow heart beats and fast heart beats. In our paper we suggest the enhancement of an implantable closed loop system to monitor and control the heart beating. We will design and simulate our system using LabVIEW
