Left Anterior Fascicular Block Symptoms, Causes, Treatment
It is a condition of heart in which heart muscles show irregular contraction. It occurs due to blockage of anterior half of bundle of His. Bundle of His is the group of cells which are responsible for transmitting electrical impulses from AV node towards apex of heart. Due to blockage of anterior half of bundle of His electrical delay in nerve impulse transmission across heart muscles occurs. And as a result delay in pumping activity of heart occurs. Left anterior fascicular block is also known as left anterior hemiblock.
It is observed via Electro cardio gram of heart. This condition is commonly seen in patient with myocardial infarction. Other conditions with associated left anterior fascicular block involve hypertension, valvular disorder, degenerative fibrotic disease and cardiomyopathy. It is the abnormal condition of left ventricle of heart. It closely resembles left bundle branch block LBBB but both of them are different conditions. In left anterior fascicular block, only the left half of bundle is involved.
The Electro cardio gram shows deviation of left axis. Patients with pre existing inferior wall myocardial infarction cannot be easily diagnosed for left anterior fascicular block because myocardial infarction itself causes deviation in left axis.
When left anterior half of bundle of His is blocked, it leads to irregular or abnormal contraction. It is an asymptomatic condition and does not show any specific symptoms. It can only be diagnosed with Electro cardio gram. Some common symptoms which are related to associated condition involve severe pain in chest region which is intermittent and occur again and again. Pain occurs due to blockage in circulation. Patient may go faint due to improper functioning of heart. On touch, patient can feel double beat I.e. the two ventricles do not beat at a time but bear one at a time.
There are no of conditions which may lead to left anterior fascicular block. Some common conditions are listed below.
The treatment strategy depends upon the severity of condition and degree of blockage. Management is required along with treatment for best results. Dietary modifications are required. Patient is asked to take low carb, low fat and high protein food. Patient is asked to take supplements like omega 3 fatty acids and vitamins. Intake of poly unsaturated fats is recommended. Physical activity is necessary, as it helps a lot in managing tis condition. If patient is a smoker or alcoholic, then he is asked to quit smoking and alcohol consumption as it can cause vasoconstriction.

Left Anterior Fascicular Block Symptoms
When left anterior half of bundle of His is blocked, it leads to irregular or abnormal contraction. It is an asymptomatic condition and does not show any specific symptoms. It can only be diagnosed with Electro cardio gram. Some common symptoms which are related to associated condition involve severe pain in chest region which is intermittent and occur again and again. Pain occurs due to blockage in circulation. Patient may go faint due to improper functioning of heart.

Left Anterior Fascicular Block Causes
There are no of conditions which may lead to left anterior fascicular block. Some common conditions are listed below.
- Chronic hypertension is considered the most common cause of left anterior fascicular block.
- Degenerative fibrotic diseases leads to blockage of anterior half of bundle of His.
- Aging
- Aortic stenosis is responsible for development of this condition.
- Valvular disorder also cause blockage of bundle of His.
- Myocardial infarction. But only 4 percent of cases show left anterior fascicular block.
- Dilated cardiomyopathy.
- Aortic root dilation and some lung diseases can also cause blockage.
Left Anterior Fascicular Block Treatment
The treatment strategy depends upon the severity of condition and degree of blockage. Management is required along with treatment for best results. Dietary modifications are required. Patient is asked to take low carb, low fat and high protein food. Patient is asked to take supplements like omega 3 fatty acids and vitamins. Intake of poly unsaturated fats is recommended.
