Heart Blocks Treatment Market - Global Industry Analysis, Trends and Forecast, 2014 – 2020

Heart block is a disease of electrical system of the heart that controls the rate and rhythm of the heart. A heart block occurs if there is slowed and disturbed electrical signals while travelling to heart. People have inherited congenital heart blocks as well as acquired heart blocks that develop after birth. Based on the working of electric signal, heart block is of two type’s namely partial heart block and complete heart block. In partial heart block, the electrical signals are blocked partially i.e., their arrival to the heart is delayed. In complete heart block, signals transmission gets blocked completely.

Heart blocks are also classified as sinoatrial node (SA node) nodal block, atrioventricular node (AV node) nodal block and infra-Hisian blocks. SA node block is not hazardous since, the alternate of SA node i.e., AV will function in place of SA node and would start beating at higher rate to compensate the blood flow. As compared to SA node, AV node block is serious a condition as the functionality of AV node is not taken by other heart components. Block of distal conduction system of heart is known as infra-Hisian block.

Heart blocks can also be segmented as first degree heart block, second degree heart block and third degree heart block. In first-degree heart block, electrical signals are slowed as they move from atria (upper chamber of heart) to ventricles (lower chamber of heart). Usually, first-degree heart block does not cause any symptoms and hence do not require treatment. In second degree heart block, electrical signals are slowed in large degree between atria and ventricles. Sometimes, several signals don't reach ventricles. If electrical signals do not reach ventricles, they won't contract and pump blood to the lungs along with the rest of body. Second degree heart blocks are of two types: Mobitz type I and Mobitz type II. In third degree heart block,...
