WPW ECG

Wide QRS complex tachycardia can be originated by 3 main mechanisms1: Ventricular tachycardia (VT). Supraventricular tachycardia (SVT) with an aberrant conduction attributable to a preexisting bundle-branch block or functional bundle-branch block induced by the fast heart rate.

Sinus tach and most SVTs have only one P wave for each QRS complex . They may or may not be buried in the preceding T waves. But there are other supra-ventricular tachycardias that have more than one P wave for each QRS or no P waves.6 Şub 2017

A supraventricular tachycardia diagnosis is confirmed with an ECG . Supraventricular tachycardia is a rapid heart rate (tachycardia, or a heart rate above 100 beats per minute) that is caused by electrical impulses that originate above the heart’s ventricles.5 Nis 2017

Supraventricular tachycardia is suspected when a doctor or nurse counts a very rapid heart rate (>200) during an attack . To confirm the diagnosis, your child’s pediatrician might perform an electrocardiogram (ECG – also known as EKG). An ECG is a test which records the electrical activity of the heart.
