Cardiac pacemakers are medical devices widely used to treat heart diseases. Mod- ern pacemakers are ultra low power embedded systems with programmable function- alities, which include acquisition of heart signals samples and statistical histograms of paced, sensed and other events. This programmability is commonly offered by an internal custom-designed processor for the application. These custom-designed processors increase product cost and time to market. Research on pacemakers has been limited because of the lack of information available in open technical literature. This thesis presents a pacing system implemented in a general purpose low power microcontroller, the msp430f1611. Furthermore, a methodology for the development of the whole pacing system, including software flowcharts and control software source code is presented. Techniques to achieve low power consumption by the software are offered. The software consumes a maximum of 10 μA, with a typical value of 5 μA.
