Overview

Echocardiography

  • Ultrasound can be used in cases of first degree AV block in order to follow the improvement in the cardiac output when the dual chamber pacing used.
  • Ultrasound can therefore be used to evaluate the need of the patients with first degree AV block to a permanent pacemaker.

More recently, cardiac resynchronization therapy (ie, biventricular pacing) has been applied in patients with cardiomyopathy, congestive heart failure, or intraventricular conduction delay (IVCD). First-degree AV block is frequently present in these patients as well.[1]
