Abstract

Reduced lead systems (RLS) typically derive (estimate) unrecorded target leads by a weighted sum of recorded basis leads. A proposed approach is to use patient-specific (PS) weights in the summation of the basis leads. Using this approach, weights are generated based on an individual subject's 12-lead electrocardiogram (ECG). These PS weights are subsequently used to derive unrecorded target leads. In this study we assess the estimation accuracy (EA) of a RLS that utilizes PS weights to derive target leads v1, v3, v4 and v6 from basis leads I, II, v2 and v5. This assessment is performed on two different monitoring scenarios during which:(1) the cardiac state of the patient remains stable after the PS weights are generated; and(2)the patient's ECG develops signs of acute myocardial ischemia after the PS weights are generated from a normal ECG.
