In this paper, the implementation of an embedded system based on a new micro-system device for real-time analysis
of ECG signals has been investigated. The system has been tested successfully on simulated ECG signals for different
heart diseases including files containing atrial fibrillation cases where P ware change sin the form and duration. In this
method, a logical approach has minimized overall memory size by storing only three bytes for each heart rate variation.
We integrated a blood pressure sensor and temperature sensor to the previous work. We focused on improvement of
software for real time diagnosis embedded on microcontroller. A graphic user interface were added, not in the
previous work [1], to facilitate the interaction and assimilation of patient data from the care givers either nurses or
doctor. Hence the overall diagnosis time and the amount of data handled is also minimized. The time taken for the
state of any heart condition to be assessed is the time to record two successive diagnosis bytes.
