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 ...

QUEBEC, QC — A new study shows that patients who harbor preexisting right bundle branch block (RBBB) face a significantly higher risk of death 2 years after transcatheter aortic-valve replacement ...

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 ...

DEAR DR. ROACH: I am a 66-year-old woman who recently had an ECG prior to my knee surgery. The interpretation I received stated that I had an abnormal ECG with a “left anterior fascicular block.” ...

A trifascicular block is the combination of a right bundle branch block, left anterior or posterior fascicular block and a first degree AV block (prolonged PR interval). The term “trifascicular block” ...

The correct answer is sinus pause due to sinus node exit block. The rhythm is regular at a rate of 80 beats/min, although two long RR intervals (└┘) with a rate of 40 beats/min are present in the ...

Almost one-third of patients undergoing transcatheter aortic valve replacement (TAVR) with a balloon-expandable device develop new-onset left bundle branch block, although the condition resolves by ...

Your heart isn’t plugged into an outlet. And you don’t use a switch to turn it on. But just like a lamp, your heart runs on an electrical system. Every time your heart beats, an electrical signal ...

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) ...

Left bundle branch block (LBBB) is a type heart block. It results from a problem with the electrical conduction system that enables the heart to beat. It may cause no symptoms, but an ...
