This paper presents the improvement of sensitivity of a system based on human heart, using PID tuning method. The Ziegler-Nichols method is used for PID tuning. For better result it is required to get desired performance specification in term of achieving maximum overshoot and specified settling time of the closed loop response .The proposed transfer function of heart and pacemaker is used in this paper with PID tuning to increase the sensitivity and Jury’s test which is a stability test used for Z domain stability has also been applied to analyse that this system is also stable in Z domain.
