WebFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size. WebIschemic T waves rise and then fall below the cardiac resting membrane potential; Hypokalemic T waves fall and then rise above the cardiac resting membrane potential; Wellens' Syndrome is a pattern of biphasic T waves in V2–3.
