first-degree atrioventricular block









































first-degree atrioventricular block (av block), is a disease of the electrical conduction system of the heart in which the pr interval is lengthened beyond 0.20 seconds.









































in first-degree av block, the impulse conducting from atria to ventricles through the atrioventricular node (av node) is delayed and travels slower than normal. it has a prevalence in the normal (young adult) population of 0.65-1.1% and the incidence is 0.13 per 1000 persons.

first-degree atrioventricular block
the human heart is a four-chambered organ responsible for the distribution of blood throughout the body. while every physiological effort is made to ensure that such a vital organ can operate continuously without error, sometimes a pathological situation arises and the function of the heart is compromised. one such pathology arises when the electrical signal propagated throughout the heart (responsible for the heart's highly organized contractions) is hindered, resulting in a degradation of said conduction. this is referred to as a bundle branch block and is seen clinically as rate-dependent bundle branch block, right bundle branch block or left bundle branch block, in varying severity (first degree av block, second degree av block and third degree av block)
tachycardia-dependent bundle branch block
