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) ...

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 ...

The functions we perform are connected to each other and it is hard to determine the actual cause of problem in the first look. Tissues are connected to the heart in a certain way that creates ...

A person with RBBB typically does not have symptoms and may not know they have the condition. On rare occasions, a person may faint due to a severe block, though this is unlikely to occur unless other ...

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 ...

QRS duration greater than 120 milliseconds Absence of Q wave in leads I, V5 and V6 Monomorphic R wave in I, V5 and V6 ST and T wave displacement opposite to the major deflection of the QRS complex A ...

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 ...

A 31-year-old woman with no significant medical history presents with intermittent heart palpitations, dizziness, shortness of breath, and fatigue provoked by exercise. Can you make the diagnosis? A ...

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 ...
