Predominantly upward P wave, QRS complex and T wave in aVR. This is opposite of what is seen in a normal ECG. The above findings are similar to that seen in a person with dextrocardia; however ...

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 ...

The three irregularly irregular rhythms are atrial fibrillation, atrial flutter with variable conduction and multifocal atrial tachycardia (similar to wandering atrial pacemaker). Atrioventricular ...

but reflects early repolarisation with J point elevation and a high take-off with downsloping ST segment followed by a negative T wave (figure 10). The most commonly used voltage criterion for LVH is ...

Normally, there is no electrical activity (flat ECG) between ventricular depolarization (reflected by the QRS complex) and repolarization (T wave), corresponding to the ST segment, because all ...

1 The majority of disorders associated with increased risk of sudden cardiac death (SCD), such as cardiomyopathies and primary electrical diseases, are suggested by abnormal findings present on an ECG ...

In a “normal” electrocardiogram (ECG), the transition of the QRS axis in the precordial leads ... atrial fibrillation, T wave inversion, and minor Q waves. Cox analysis found a positive ...

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 ...
