What causes intraatrial conduction block?

1, electrolyte

disorder occurs in patients

with electrolyte disorder

, may cause damage to myocardial cells, eventually leading to myocardial contractility decreased, causing various arrhythmias, conduction block and other diseases.

2, cor

pulmonale is a serious respiratory and circulatory system disease, accompanied by respiratory failure and heart failure symptoms, when cor pulmonale can not be effectively improved, it will increase the load of the heart, leading to heart failure, causing atrial conduction block.
