Advances in Electronics for Digital Electrocardiography

Ventricular Late Potentials, or shortly VLP, are localized signals of very small amplitude, which occur in electrocardiograms of subjects with high resistivity myocardial areas. In advanced electrocardiography their correct detection is very useful in diagnosis and prevention of serious heart diseases, such as tachycardia. Some standards have been proposed to detect VLP, but new technologies and computing power allow more effective analysis. The development of acquisition and elaboration hardware of increasingly better performance allows an advanced signal processing of high quality signals, even in real time. The aim is therefore to set new standards for detection methods, and add an automatic VLP control in standard ECG analysis. This would be a big step forward and could save lives.
