HEART BLOCK POEM-EASY WAY TO REMEMBER
What is heart block? Heart block is a type of heart rhythm disorder (arrhythmia). It is the slowing down or interruption of the electrical signal from the upper chambers of the heart (the atria) to the lower chambers (the ventricles). The electrical signal causes the heart muscle to contract and the heart to beat. A slow heartbeat of less than 60 beats per minute is called bradycardia. Heart block may develop in adults or children. Babies can be born with a heart block if they have a congenital heart defect or their mom has an autoimmune disease like lupus. This is called congenital heart block. Sometimes, no cause can be identified. Types Heart block is classified by how much the electrical signals between the atria and the ventricles are slowed down. There are three types of heart block: First-degree heart block is the mildest form and usually doesn’t cause symptoms. Electrical signals are slowed, but they all reach the ventricles. Second-degree heart block has a slower – and sometimes irregular – heart rhythm. Not all signals reach the ventricles and some heart beats are dropped. Third-degree heart block (complete atrioventricular block) is the most severe form. None of the electrical signals reach the ventricles. A natural back-up system in the ventricles takes over, but the heart rhythm is slower and more irregular than normal. Reference:https://www.heartandstroke.ca/heart-disease/conditions/heart-block
