The different parts of the ECG will be described in the following sections. A normal ECG contains waves, intervals, segments and one complex, as defined below. Wave: A positive or negative ...

it is the time to learn what the normal P wave looks like and what it represents. It’s a similar concept for the other parts of the ECG. The Learn the Heart ECG Basics module contains detailed ...

The ECG records the small electrical voltage changes generated on the body surface by cardiac bioelectricity, reflecting changes in individual-cell transmembrane voltage (called action potentials ...

Multiple other ECG traits have also emerged as potential predictors of stroke, namely cardiac electrical/structural remodeling – Q wave, QRS/QT duration, bundle blocks, P wave duration/amplitude ...
