An electrocardiogram is a picture of the ... of the ECG will be described in the following sections. A normal ECG contains waves, intervals, segments and one complex, as defined below.

The resting electrocardiogram (ECG ... and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT interval duration.

Pericarditis, or inflammation of the pericardium, has typical ECG findings. These findings occur in progressive stages, all of which are seen in about 50% of cases of pericarditis. Stage I (acute ...

In 'Bedside to Bench', Stanley Nattel examines recent clinical studies suggesting that a particular type of readout on an electrocardiogram ... corresponding to the T wave on the ECG), are ...

In a “normal” electrocardiogram (ECG), the transition ... atrial fibrillation, T wave inversion, and minor Q waves. Cox analysis found a positive association between clockwise rotation and ...

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 ...

The regular arrhythmia occurring at the beginning of the electrocardiogram was identified as ventricular bigeminy. Single ventricular premature complexes (VPCs), as well as pairs and triplets of ...

The goal of ECG interpretation in athletes is to classify the ECG as: (1) ‘normal’—no further evaluation needed ... These include findings suggestive of cardiomyopathy such as T-wave inversion, ST ...
