Abstract :
The role of ischemia in arrhythmogenesis has not been well established. From the ambulatory ECG the most common measure of ischemia is the ST segment using a 100 μVolt threshold. The premature ventricular beat (PVB) was the focus of this study and a contextual analysis of the ST was performed to see if quantifiable, subclinical (<100 μV) changes in the ST segment presage these PVCs
