Remember that T wave inversions and ST segment depression are normal in leads V1 to V3 in the presence of a right bundle branch block; thus, myocardial ischemia technically cannot be easily determined ...

Conduction system pacing (CSP) produced the same degree of cardiac resynchronization, ventricular reverse modeling, and similar clinical outcomes as did biventricular pacing (BiVP) in patients with ...

Atrial fibrillation with an uncontrolled ventricular response Left bundle branch block Premature ventricular contractions At times it can be difficult to distinguish "SVT with aberrancy" from ...

Pacing Clin Electrophysiol. 2008;31(2):229-231. A 52-year-old man was admitted in our institution with cranial traumatism due to a syn-copal episode that occurred while he was walking. Several weeks ...

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 ...

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.

An ST depression is a possible outcome of an electrocardiogram (ECG) test. It can indicate health conditions such as hypokalemia, myocardial ischemia, or a side effect of medications. Doctors may ...

A 70 year old man presents to the surgery with a history of exertional breathlessness and swelling of his ankles. An ECG was done as part of his diagnostic work up. What does the ECG show? A ...
