Patent ductus arteriosus electrocardiogram
Introduction
Overview
Overview
Electrocardiogram (ECG) differs in patent ductus arteriosus (PDA) due to its size. It can be normal, showing signs of left ventricular hypertrophy or at late course of the disease, showing right ventricular hypertrophy.
Electrocardiogram
Electrocardiogram
An electrocardiogram will appear differently depending on the severity of disease onset. In general, one can expect:[1][2][3]
- Small PDA: The EKG is normal.
- Medium-sized PDA: There is LVH, LA increase, prolonged PR interval and eventual atrial fibrillation.
- Large-sized PDA: It is similar to that of a VSD complicated by pulmonary hypertension. One can also expect:
- Evidence of left ventricular hypertrophy (LVH) is decreased or absent because there is essentially normal volume work by the left ventricle (LV).
- There is right ventricular hypertrophy (RVH) instead with a large R wave in V1. No Rsr’ like atrial septal defect (ASD).
- Marked right axis deviation is common.
- Peaked right atrial (RA) ”P waves” are present
