<span lang="EN-US">Due to the growing number of cardiac patients, an automatic detection that detects various heart abnormalities has been developed relieve and share physicians’ workload. Many depolarization ventricles complex waves (QRS) algorithms with multiple properties have recently presented; nevertheless, real-time implementations in low-cost systems remain a challenge due limited...

The recent development of biomedical signal processing, information technology and communication has brought a new dimension to the medical world. It is now possible to record an ECG signal with a portable electrocardiograph lightweight and able to transform a micro-computer in electrocardiograph with the possibility of a diagnostic aid for automated interpretation. Applications focusing on por...

It has been shown experimentally that three bipolar electrocardiograms from the main axes of the body contain as much or more information about QRS forces than 12-lead electrocardiograms (Frank et al., 1955; Schmitt and Simonson, 1955; and Newman et al., 1955). A clinical comparison of such a three-lead system and the 12 conventional leads has not yet been reported, and one aim of the present s...

I experimental medicine it is sometimes useful to be able to record a single-channel electroencephalogram. Anaesthetists, in particular, are now interested in the effect of anaesthetics upon the encephalogram and may have access to a direct-writing electrocardiograph but not to an electroencephalograph. The unit described can be added to most electrocardiographs, so that they then become suitab...
