Intracardiac conduction block,
conduction block occurring below the junction of the atrioventricular bundle branches.
This is a symptom commonly seen in cardiac lesions, mostly resulting from organic changes in the heart itself.
Common causes include coronary heart disease, cardiomyopathy, myocarditis, hypertension, rheumatic heart disease, and pulmonary heart disease.
Some are also caused by other diseases, like electrolyte imbalance, neuromuscular diseases, diabetes, etc.
And a very small portion occurs in healthy individuals.
What truly surprises them is that this condition cannot be detected even with a stethoscope; at the very least, an electrocardiogram is required to find abnormalities.
There are usually two types of conduction block, one is intracardiac conduction block, and the other is atrial conduction block.
If it is atrioventricular block, it is generally divided into first degree, second degree, and third degree with varying severities.
