ECG

1. FASCICULAR
BLOCK
BY SANA AKHTAR
BS CARDIOLOGY

3. •Fascicular block is a disruption in the electrical conduction pathways
of the heart, specifically affecting the fascicles (bundles of fibers) that
transmit impulses from the atrioventricular (AV) node to the
ventricles.
FASCICULARBLOCK

4. 2) Left anterior fascicular block (LAFB):
Affects the anterior fascicle of the left bundle branch
3) Left posterior fascicular block (LPFB):
Affects the posterior fascicle of the left bundle branch
FASCICULAR BLOCK TYPES

6. Left Anterior Fascicular Block
•Left axis deviation(usually between -45 and -90 degrees).
•Small Q waves with tall R waves (qRcomplexes) in leads I & Avl.
•Small R waves with deep S waves (rScomplexes) in leads II, III, aVF.
Left Posterior Fascicular Block
•Right axis deviation(> +90 degrees).
•Small R waves with deep S waves(rScomplexes) in leads I & aVL.
•Small Q waves with tall R waves (qRcomplexes) in leads II, III and aVF.

7. •Coronary Artery Disease:
Hardening of the arteries that supply blood to the heart.
•Hypertension:
High blood pressure that damages the heart's conduction system.
•Cardiomyopathy:
Diseases that affect the heart muscle, such as dilated
cardiomyopathy.
•Myocardial infarction:
Heart attack that damages the heart's conduction system.
FASCICULAR BLOCK CAUSES

8. SYMPTOMS
•Dizziness: Due to decreased cardiac output.
•Lightheadedness: Caused by reduced blood flow to the brain.
•Shortness of breath: Resulting from decreased cardiac output.
•Fatigue: Due to decreased cardiac efficiency.
•Palpitations: Abnormal heart rhythms.

9. DIAGNOSIS
•1. Electrocardiogram (ECG): To identify characteristic patterns of
fascicular block.
•2. Echocardiogram: To evaluate cardiac function and structure.
•3. Cardiac catheterization: To assess coronary artery disease.

10. TREATMENT
•Medications: To control symptoms and manage underlying
conditions.
•Pacemaker implantation: To regulate heart rhythm.
•Coronary artery bypass grafting: To treat underlying coronary artery
disease

11. COMPLICATIONS
•Complete heart block:
A life-threatening condition requiring immediate medical attention.
•Ventricular arrhythmias:
Abnormal heart rhythms originating in the ventricles.
•Cardiac arrest:
Sudden loss of cardiac function.
