Left posterior fascicular block
Left Posterior Fascicular Block
Left Posterior Fascicular Block (LPFB), pronounced as /lɛft pɒˈstɪərɪər fəˈsɪkjʊlər blɒk/, is a cardiac conduction abnormality seen on an Electrocardiogram (ECG). It is a type of intraventricular conduction delay where the electrical impulse is blocked in the posterior fascicle of the left bundle branch.
Etymology
The term is derived from the Latin fasciculus, meaning "little bundle", and block, from the Old French bloc, meaning "a log or block". The term refers to the blockage of electrical impulses in the posterior fascicle of the left bundle branch in the heart.
Definition
In a Left Posterior Fascicular Block, the electrical impulses that control the heartbeat are partially or completely blocked from reaching the posterior fascicle of the left bundle branch. This can result in an abnormal heart rhythm, known as a cardiac arrhythmia.
Symptoms
Symptoms of LPFB may include dizziness, fainting, shortness of breath, or palpitations. However, many people with LPFB do not experience any symptoms.
Diagnosis
Diagnosis of LPFB is typically made through an Electrocardiogram (ECG), which can show characteristic changes in the electrical activity of the heart.
Treatment
Treatment for LPFB is usually aimed at managing the underlying cause of the block. This may include medications, pacemaker implantation, or other treatments as appropriate.
