The standard ECG has 12 leads ... parts of the ECG will be described in the following sections. A normal ECG contains waves, intervals, segments and one complex, as defined below.

These ECG findings in athletes are considered normal, physiological adaptations to regular exercise and do not require further evaluation (box 1). Convex (‘domed’) ST segment elevation combined with T ...

How often do you see an ECG that is just a little off? Maybe the T wave is flat, oddly-shaped or inverted. Maybe the ST segment is coved, very minimally-depressed or shows some J point elevation.

pathological Q-waves, left axis deviation and conduction delays and findings suggestive or diagnostic of primary electrical diseases such as long QT syndrome and Wolff-Parkinson-White syndrome. The ...

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 ...

These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...
