Left ventricular conduction block, generally referred to as left bundle branch conduction block, can be treated using general therapy, medication and surgery. 1. General treatment: If it is a simple conduction block with no other combined block, no treatment is needed. 2. Drug treatment: there are some differences between individuals, and it is recommended to use drugs under the guidance of doctors; for conduction block caused by organic heart disease, antiplatelet drugs (aspirin, clopidogrel), lipid-regulating drugs (atorvastatin), vasodilators (nitroglycerin), diuretics (furosemide, hydrochlorothiazide) and other drugs can be used to treat the block. 3. Surgical treatment: If there is ventricular dyssynchrony, ECG QRS wave greater than 150 milliseconds, left ventricular ejection fraction less than 35%, etc., cardiac resynchronization therapy device can be implanted and surgical treatment can be applied. In the presence of left ventricular block, it is recommended to go to the hospital in time, timely treatment, and not to blindly use medication on their own.
