An Introduction to ECG Signal Processing and Analysis

  • Chapter
  • First Online:

Abstract

ECGs are important biomedical signals, which are reflective of an electric activity of the heart. They form a subject of intensive research for over 100 years. ECG signals are one of the best-understood signals being at the same time an important source of diagnostic information. Because of this, in the recent years there has been a steady and intensive research with intent of developing efficient and effective methods of processing and analysis of ECG signals with emphasis on the discovery of essential and novel diagnostic information.This chapter offers a comprehensive overview of main problems concerning analysis and signal processing in ECG systems. Here the systems are meant in a broad sense embracing monitoring, diagnostic and therapeutic systems, whose functioning relies in one way or another on the analysis of electrocardiograms. In general we will be referring to them as ECG systems. An analysis of ECG signals requires their preprocessing and a suitable representation so that depending upon the nature of the ECG system, it helps reveal the required diagnostic information.The chapter is arranged into three parts. In the first one, we focus on the essentials of ECG signals, its characteristic features, and the very nature of the associated diagnostic information. In the second part, we elaborate on a sequence of phases of ECG signal processing, and analysis as they appear in ECG systems. Finally, in the third part, we offer a description of essential ECG tests.
