ICD Code I44.4

ICD code I44.4 is a diagnosis for left anterior fascicular block, which is a type of heart conduction abnormality where electrical signals are delayed or blocked in the left anterior fascicle of the heart's conduction system.

1. Evidence of left axis deviation on electrocardiogram (ECG), typically between -45° and -90°

2. QRS duration less than 120 milliseconds (unless associated with other conduction abnormalities)

3. rS pattern in leads II, III, and aVF

4. qR pattern in leads I and aVL

5. Absence of other causes of left axis deviation, such as left ventricular hypertrophy or inferior myocardial infarction

6. Patient may be asymptomatic or present with symptoms such as palpitations, dizziness, or syncope
