"ECG Monitor VLSI Design from Concept to Silicon" is an excellent reference for digital system design engineers. It provides a step by step guide to the design and test of a QRS detection algorithm, an essential part of electrocardiogram devices. The book contains detailed design examples of the system functional blocks which range from the architecture level design to the HDL description at the RTL level. It also outlines the power reduction techniques applied at the circuit level in such systems. This allows the design of energy efficient portable ECG monitors.
