As of December 2014, there is no known therapy to treat a left anterior fascicular block. However, a biventricular pacemaker, also known as cardiac resynchronization therapy, may be used to help prevent heart failure associated with this disorder, according to University of California San Francisco.Know More
A biventricular pacemaker is a battery-powered device used to balance the heart's contractions in patients that show delays in ventricular action within the heart. This therapy is done for people with advanced heart failure, notes Cleveland Clinic.
In April 2013, researchers announced new findings with regard to left anterior fascicular blocks, or LAFB, a heart condition previously thought to be harmless. Scarring in the left ventricle of the heart led to greater instances of atrial fibrillation, congestive heart failure and death in otherwise healthy patients over the age of 65, notes UCSF. Risk of heart failure increased by 143 percent in patients with LAFB. Doctors plan to study specialized pacemakers as a possible treatment for LAFB in order to prevent heart failure. Lifestyle changes, exercise and not using tobacco are other ways to help reduce the overall risk of heart problems.
LAFB prevents electrical signals from reaching parts of the left ventricle of the heart, according to UCSF. As of December 2014, researchers don't known why or how fibrosis, or scarring of the heart, is associated with this electrical block.Learn more about Cardiac Health
LearntheHeart.com states that an anterior myocardial infarction is when the anterior, or front, wall of the heart experiences injury due to lack of blood flow. An artery known as the left anterior descending coronary artery usually supplies blood flow to this area of the heart. An anterior myocardial infarction generally indicates that there is a blockage in this artery.Full Answer >
A bundle branch block is a heart complication that occurs when the electrical impulses that control heartbeats are delayed, according to Mayo Clinic. An obstruction may block one of the pathways, or bundles, leading to the right or left ventricle, the chambers in the heart.Full Answer >
Symptoms of second- and third-degree heart block include fatigue, fainting, dizziness, lightheadedness and shortness of breath. A person suffering from first-degree heart block may not have symptoms, according to the National Heart, Lung and Blood Institute.Full Answer >
Left atrial enlargement is a diagnosis made when the left atrium of a person's heart is larger than normal. The Ochsner Journal explains that left atrial size is measured through echocardiography. The recommended way to determine the size of the left atrium is to measure its volume. Although linear dimensions may also be measured, this method is less accurate.Full Answer >
