Heart conduction blocks and artery changes explained by Dr Thosteson
Dr Thosteson clarifies that left bundle branch block does not block a heart chamber but delays impulse conduction in the ventricles and may accompany heart disease. An electrocardiogram detects blocks, while there is no surgery for them. pacemakers and medications help. The heart attack is due to artery branch blockage, with smaller branches enlarging to compensate. Cancer is not contagious, and Caesarean deliveries may recur if the underlying condition persists.
