Impulses, or electrical signals, travel through both the left and right chambers of your heart to make it pump. But if the pathway is blocked, the impulses may move slower than normal or irregularly.

Sinus tachycardia Right bundle branch block Left anterior fascicular block Anterior myocardial infarction Recall that myocardial ischemia can indeed be interpreted in the setting of a right bundle ...

This ECG is challenging. The rhythm starts as normal sinus rhythm with a right bundle branch block, then a wide-complex tachycardia develops in a left bundle branch block pattern. The important thing ...

The correct diagnosis is normal sinus rhythm, right bundle branch block (RBBB), left anterior fascicular block, bifascicular disease, blocked (nonconducted) premature atrial complexes in a trigeminal ...

The diagnosis is normal sinus rhythm, interpolated premature ventricular complexes (PVCs) in a trigeminal pattern, retrograde concealed conduction, intraventricular conduction delay, and old inferior ...

A right bundle branch block (RBBB) involves a delay in the electrical impulses reaching the heart’s right ventricle, which can affect the heart’s ability to pump blood effectively. While RBBB doesn’t ...

keyboard The American College of Cardiology, the American Heart Association, and the Heart Rhythm Society have released a guideline on the evaluation and management of patients with bradycardia and ...

In order for your heart to beat properly, your heart’s tissue conducts electrical impulses throughout your heart muscle in a regular pattern. This electrical impulse causes the upper chambers (atria) ...
