The compensatory pause after the PVC is slightly longer than the junctional escape interval and allows the junctional rhythm to escape for 5 beats. During this period, the P waves from the sinus ...

Children with congenital complete atrioventricular block often require lifelong pacemaker therapy. Although such therapy restores a normal heart rate, it also results in dyssynchronous left ...

Is there a simple way to differentiate a supraventricular tachycardia from a ventricular, wide QRS tachycardia on a rhythm strip? The simplest initial approach is to look at the lead with the most ...

There are two different rates that can be determined on an ECG. The atrial rate is indicated by the frequency of the P waves. The ventricular rate is indicated by the frequency of the QRS complexes.

The ECG shows regular P waves at 60 beats per minute (bpm) with no conduction to the ventricles. The ventricular rate is about 70 bpm with QRS duration of 0.20 and a left bundle branch block (LBBB) ...

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 VPCs, ...
