What are the direct causes of sudden cardiac death?

The direct causes of sudden cardiac death are ventricular fibrillation, temporary functional factors and organic heart disease.

1. Ventricular fibrillation sudden

cardiac death is more common in ventricular fibrillation. When ventricular fibrillation occurs, patients may die because they do not receive timely defibrillation treatment.

2. Temporary functional factors

If there are temporary functional factors in the patient's body, including ECG instability, platelet aggregation, coronary artery spasm, etc., they may lead to abnormal instability of stable cardiac structure.

3. Organic heart disease

Organic heart disease generally has coronary heart disease and hypertrophic cardiomyopathy. If the condition is more serious and sudden, it may cause sudden cardiac death without timely treatment.
