The ECG criteria for a right bundle branch block include the following: QRS duration greater than 120 milliseconds; rsR’ “bunny ear” pattern in the anterior precordial leads (leads V1-V3) ...

Type #4: Acute MI with a Right Bundle Branch Block. ... Here is the anterior STEMI with a right bundle branch block ECG. Enlarge . Now, here is an inferior STEMI with a RBBB on the ECG.

Right bundle branch block is a conduction abnormality with the heart that can result in an abnormal heart rhythm. ... (ECG), a test that evaluates the heart’s electrical activity.

Noted are several QRS complexes that have an increased duration (0.12 sec) with a right bundle branch block (RBBB) morphology with an RSR’ morphology in lead V1 (←) and a broad terminal S wave ...

ECG monitors made for at-home use can be a useful tool. Here’s what to consider, plus six to take a closer look at.

Learn what an ECG can tell you, how the technology works, and which smartwatches offer the feature. With heart rate monitors now standard in smartwatches and fitness trackers, electrocardiograms ...

The morphology resembles neither a left nor a right bundle branch block. Q waves occur in leads II, aVF, and V5-V6 (↑). The ST segment is also elevated in these leads ( ).
