The ventricles are the lower chambers of the heart. The human heart has 2 ventricles, the right ventricle receives blood from the right atrium and pumps it to the lungs through the pulmonary artery. The left ventricle receives blood from the left atrium and pumps it into the circulatory system through the aorta.

The heart is an organ that plays a very important role in carrying blood and oxygen to nourish the whole body. The heart's blood pumping cycle is likened to "a power plant" providing 5-6 liters of blood per minute to maintain human life.

Atrioventricular block is a condition in which the transmission of electrical impulses in the heart from the atria to the ventricles is partially or completely interrupted. Atrioventricular block is classified into 3 different grades, of which second-degree AV block is moderate but can still cause many dangerous complications.

Atrioventricular block is a condition in which the system that conducts electrical impulses in the heart from the atria to the ventricles is disrupted. Atrioventricular block is classified into 3 different grades, of which first-degree AV block is the mildest. So is 1st degree atrioventricular block dangerous?
