atrial tachycardiaa rapid heart rate, between 140 and 250 beats per minute, with the ectopic focus in the atria and with no participation by the atrioventricular node or the sinoatrial node. It is recognizable on the electrocardiogram because the P wave precedes the QRS complex, as opposed to ...
Ventricular tachycardia can occur with many variations of the QRS morphology, depending on where the arrhythmia originates, which sometimes makes diagnosis on ECG challenging. Below are two examples of ventricular tachycardia with different QRS morphologies — one with a right bundle branc...
ECG Library Save Ventricular Arrhythmias Other Enlarge 1. Ventricular tachycardia This ECG shows a wide-complex tachycardia in a right bundle branch block pattern going quite fast (heart rate about 150 BPM). Note the morphology of the QRS complex in lead V6. There is a RS complex in this le...

Some histopathological studies have pointed to left ventricular fibrosis as the underlying cause of arrhythmia in MVP patients. Fragmented QRS (fQRS) on electrocardiography (ECG) has been shown to be a marker of myocardial fibrosis. This study aimed to investigate the association between fQRS and ...
The aim of this work was to undertake a paper of all studies conducted to assess the impact of QRS duration on the development of life-threatening ventricular arrhythmias in repaired TOF subjects. QRS complex corresponds to the depolarization of the right and left ventricles. Duration of the ...

Ventricular tachycardia (VT) is a potentially life-threatening arrhythmia originating in the cardiac ventricles. VT usually results from underlying cardiac diseases, such as myocardial infarction o...
On the other hand, ventricular arrhythmia from right ventricle had decreased S1 complexity score and S1 duration in comparison to adjacent sinus beats. The difference of S1 (S1) parameters between premature ventricular complex and sinus beat was significantly smaller in right ventricular arrhythmia ...
