Left Anterior Fascicular Block Treatment

What is a left anterior fascicular block?

A left anterior fascicular block is known as a cardiac condition that may often be determined by a left bundle branch block. In the case of the left bundle branch being defective, a left anterior fascicular block may be the result. Left anterior fascicular block may however be noticeable on an ECG (electrocardiogram) by the left axis deviation. A left anterior fascicular block may however be referred to as a left anterior hemiblock, this may occur when the cardiac impulses spread into the left posterior fascicle and possibly cause a delay in the start of the anterior and upper part of the left ventricle. Even though there may often be a delay or block in the activation of the left anterior fascicle, there may be some preservation of the left or right septal activation and possibly preservation of the inferior activation within the left ventricle. Questions regarding left anterior fascicular block may be very common regarding what left anterior fascicular block is, the causes, prognosis, symptoms, as well as treatments. Read below where Experts have answered many complex questions regarding anterior fascicular block.

What treatment is needed for a left anterior fascicular block and a right bundle branch block?

A right bundle branch block and left anterior fascicular block may often be referred to as a bi-*fascicular block. Often, no treatment may be needed. However, there may be situations when the bi-fascicular block may progress into a complete heart block, and a pacemaker may then be needed. In some situations, an evaluation from a medical professional may be needed in order to perform a stress test on the individual’s heart.

What might be expected after an EKG with the results of right bundle branch block and left anterior fascicular block?

A conduction pathway defect may often be suggested by the EKG (electrocardiogram) findings, meaning that there may possibly be blockages within the electrical impulse transmission from the right atrium to the ventricles. In some cases, the next step may be an exam that is performed by a doctor that may often include a stress test and an echocardiogram in order to help rule out any ischemic heart disease. If an ischemic heart disease is thought to be present, then the coronary arteries may need to be checked for the presence of blood clots. However, if no ischemic heart disease is thought to be present, then the treatment may all depend on any current symptoms. A pacemaker may however be needed if the heart rate is too low or irregular. However, if there are no symptoms present, then periodic checkups with a doctor may be all that is needed.

Is an ECG result of abnormal left axis deviation, left anterior fascicular block and incomplete right bundle branch block problematic?

This may only be an incidental finding; however, a small number of individual’s with such as EKG may progress into a complete heart block, which may often require a pacemaker. The need for a pacemaker may be proceeded by dizzy spells and/or fainting. There may be no need for concern if the symptoms have never been present. However, an exam from a medical professional may be needed in order to monitor the progress of the EKG findings.

Would a left anterior fascicular block cause discolored and numb hands with a change in an EKG from -17 to -37?

The symptoms of discolored and numb hands may often be caused by a pinching or pressure on a nerve. The pressure or pinching of the nerve may be located within the neck, spine or limbs. There may however be no irritation to the nerve roots due to degenerative changes in the spine or disc. A low circulation may often cause the numbness or discoloration. A further exam may often be needed in order to help find the exact cause of the discoloration and numbness. The left anterior fascicular block within the heart may often cause a shift from -17 to -37 on the ORS axis of an EKG.

Anytime that a left anterior fascicular block is thought to be present there may be cause for questions and concerns about the treatment or possibly even which type of Expert to turn to for advice. If you have these or similar questions you can and should ask an Expert.
