Now, look at the rhythm strip at the bottom in lead V1 to see the AV dissociation. This ECG also meets the Brugada Criteria for concordance. In this LBBB pattern, all the QRS complexes are ...
Because the normal ventricular conduction system (His-Purkinje) is used, the QRS complex is frequently narrow. A junctional rhythm is normally slow — less than 60 beats per minute. When faster ...
A 76-year-old woman presents with a persistently rapid heart rate that she attributes to her pacemaker. What does the ECG ...
Congenital third-degree AV block with wide QRS rhythm, complex ventricular ectopy, or ventricular dysfunction. Congenital third-degree AV block in infant with HR <55 beats/min, or HR <70 beats/min ...
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 ...
