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 ...

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.

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 ...

Q: I recently had an electrocardiogram as part of a routine physical exam. The report said I had a bundle branch block. What does that mean? Will I need a pacemaker? A: Bundle branch blocks are ...

Accelerated junctional rhythm Left bundle branch block Chapman's sign indicating possible acute myocardial infarction Chapman's sign is used to diagnose an acute myocardial infarction in the setting ...

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 ...

The rhythm is irregularly irregular (ie no consistency to the RR intervals). There are three supraventricular rhythms that are irregularly irregular: Sinus arrhythmia, in which there is one P wave ...

If it’s important that an ECG is done, it’s important that it’s legible. Asking patients to hold their breath for a couple of seconds can help, or if fine tremor is a problem, try moving the limb ...
