Overview
There are no echocardiography/ultrasound findings associated with AV block.
Echocardiography/Ultrasound
The presence of left bundle branch block on electrocardiogram markedly increases the likelihood of underlying structural heart disease and of diagnosing left ventricular systolic dysfunction. Echocardiography is usually the most appropriate initial screening test for structural heart disease, including left ventricular systolic dysfunction.
Abbreviations:
PPM: Permanent pacemaker;
LBBB: Left bundle branch block
