How is left anterior branch block caused?

summary

Left anterior branch block is also called left anterior half block. The left anterior branch is a slender branch of the left bundle branch, which is shallow in the ventricular septum and prone to ischemic injury. The incidence rate of left anterior branch block is about 4:1 between male and female. Male is more common. The onset age is 15-88 years old. The average onset age of male is 61.41 years old and female is 59.83 years old. How is left anterior branch block caused? Next, I'd like to share my views with you.

matters needing attention

Active treatment of etiology, such as coronary artery disease, hypertension, pulmonary heart disease, myocarditis, can prevent the occurrence and development of ventricular block. Prevent constipation, improve sleep, have the habit of continuous exercise: the best is to do aerobic exercise, will help, aerobic exercise and weight loss can reduce blood pressure, such as walking, jogging, Taijiquan, cycling and swimming are aerobic exercise.
