To detect dynamic changes of VLPs we developed a low-noise, HR-ECG with a gain of 10(5)-10(6)X. This system allows the beat-to-beat detection of low-amplitude signals at the bedside in a nonshielded room without any averaging process. Analysis was pe

The article describes a constant current generator with an internal resistance of 10 GΩ and a maximum current capability of ±200 nA on a 100 MΩ electrode. Monitoring the glass electrode resistance is possible without stopping the experiment. The c

By means of high-gain ECG and signal-averaging techniques, we tried to determine the prevalence and prognostic significance of ventricular late potentials (VLPs) in coronary artery disease (CAD). No VLPs were detected in normal subjects (n = 25) or i
