I44.6: Other and unspecified fascicular block
The heart’s electrical activity is not spreading normally to your left ventricle.
The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition. The heart's electrical currents flow within the heart. The heart's electrical activity causes the heart muscle to contract. It begins at a site in your right atrium. Initially the electrical activity spreads to both atria. The electrical activity then flows on via a sort of cable to the ventricles. The heart’s electrical impulses make the atria, and then the ventricles, contract. To achieve this, the cable which they flow through divides up into several thin cables. There are 2 cables for the left ventricle and one cable for the right ventricle.
Your heart’s electrical impulses are not flowing, or not fully flowing, through the cables for the left ventricle. If the impulses stop flowing through the cables, they spread to the ventricles in other ways.
