WebbIn the normal ECG, there is a large S wave in V1 that progressively becomes smaller, to the point that almost no S wave is present in V6. A large slurred S wave is seen in leads I and V6 in the setting of a right bundle branch block. The presence or absence of the S wave does not bear major clinical significance. WebbFigure 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.

High-take off can also be confused with pericarditis for this reason. Generally the ST elevation is minimal and each lead has its own defined T waves. There is also no ST depression on the ECG. how many pints in a 22g keg uk

"WebbECG characteristics of early repolarization The ST segment elevations are concave and most pronounced in the chest leads. T-waves have high amplitude. The hallmark of early repolarization is the end-QRS slurring or end-QRS notching (both may occur on the same ECG). The entire notch must be above the baseline. " - Slurred's wave ecg
