What causes intraventricular conduction block?

Intraventricular conduction block may be caused by conditions such as coronary atherosclerotic heart disease, myocarditis, or congenital heart disease. As the underlying causes differ, so do the treatment approaches.

1. Coronary Atherosclerotic Heart Disease: Long-standing conditions like hyperlipidemia and hypertension can predispose individuals to coronary atherosclerotic heart disease, leading to atherosclerosis or thrombotic occlusion of the coronary arteries. This obstructs blood flow through the vessels, resulting in myocardial ischemia and potentially causing intraventricular conduction block. If symptoms such as chest pain and tightness occur, medications like enteric-coated aspirin tablets or ticagrelor tablets may be used under medical guidance.

2. Myocarditis: In individuals with weakened immunity, viral or bacterial infections can lead to inflammation of the myocardium. This inflammatory process may impair the heart's ability to contract and relax properly, resulting in the aforementioned condition. If accompanied by cold-like symptoms, antiviral medications such as acyclovir capsules or valacyclovir hydrochloride tablets may be prescribed according to medical advice.

3. Congenital Heart Disease: Due to genetic defects or maternal viral infections during pregnancy, congenital malformations of the heart or blood vessels may develop, disrupting normal cardiac function and leading to intraventricular conduction block. If associated with dyspnea, interventions such as catheter-based procedures or surgical correction may be considered based on the patient's specific condition.

Besides the above-mentioned causes, other factors such as electrolyte imbalances cannot be ruled out, and further evaluation and treatment at a hospital are recommended.
