Sinus Tachycardia and Right Bundle Branch Block Recorded with an Adhesive External Ambulatory ECG Monitor

Image 1 of 2 in Series "Right Bundle Branch Block Recorded by an Adhesive External Ambulatory ECG Monitor"

Description

Sinus tachycardia at a rate of approximately 125/min and right bundle branch block (RBBB) are present. Placement of the recording device on the left side of the chest results in QRS morphologies that are similar to those seen in the lateral leads on a standard ECG. In this case, the QRS complexes are wide and contain a deep S wave.

Sinus Rhythm, Non-sustained Atrial Tachycardia and Right Bundle Branch Block Recorded with an Adhesive External Ambulatory ECG Monitor

by: Joe B. Calkins, Jr., M.D.

Normal sinus rhythm at a rate of approximately 65/min is present. A 3-beat run of atrial tachycardia at a rate of approximately 125/min is recorded (5th, 6th and 7th complexes). Note the different P wave morphology and shorter PR intervals associated with the ectopic atrial complexes. The QRS complexes are unchanged; since they are recorded by a monitor on the left anterior chest, they are wide and contain a deep S wave due to RBBB.
