Following is a list of causes or underlying conditions (see also Misdiagnosis of underlying causes of Heart block) that could possibly cause Heart block includes: 1  Heart attack. 2  Coronary artery disease. 3  Sinus node disease. 4  Congenital heart defect. 5  Myocarditis. 6  Coronary thrombosis (see Heart symptoms) 7  Cardiomyopathy. 8  Heart valve disease.
In people with heart block the electrical pulses that control the heart rate are disrupted, causing the heart to beat more slowly. It's a type of arrhythmia, which is a medical term used to describe problems with the rate or rhythm of the heartbeat.There are three levels of heart block (see below), and usually only the most serious type causes symptoms. This type of heart block is known as a complete, or third-degree, heart block.he pulse is sent to another group of cells, called the atrioventricular node (AV node), which relays the pulse to the two lower chambers of the heart (the ventricles). A heart block occurs if the transmission of the pulse between the SA node, the AV node and the ventricles is interrupted.
