Masquerading bundle branch block (MBBB), a rare condition, presents with significant cardiac damage. This case highlights MBBB in myocardial infarction with ventricular septal defect, indicating poor prognosis and high risk of advanced atrioventricular block.
Area of Science:
- Cardiology
- Electrophysiology
- Internal Medicine
Background:
- Masquerading bundle branch block (MBBB) is an uncommon manifestation of bifascicular blocks, arising from combined right bundle branch block and advanced left anterior fascicular block.
- This condition signifies extensive damage to the cardiac conduction system and is associated with a poor prognosis.

Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...
Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection....
