Abstract

T-wave abnormalities are gaining significance in the realm of electrocardiogram diagnostics. In particular, T-wave alternans are proving to be powerful predictive indicators of potentially fatal arrhythmias. T-wave morphology monitoring and analysis are the means by which alternans and other abnormalities are detected. We have presented a preliminary design of an analog T-wave monitor to provide a characteristic description of the beat-to-beat T-wave morphology in terms of its maximum leading edge and trailing edge slopes, and its area. Experimental results showed that data from the analog T-wave monitor compared well with those predicted theoretically. Current design of the T-wave monitor, once improved, can find use in the screening, diagnosis, and early detection of T-wave abnormalities in clinical settings.
