| Abstract |
|
Correlation between electrocardiographic findings and hemodynamics in 108 children with patent ductus arteriosus, confirmed by cardic catheterization at SNUH, was evaluated. The results were as follows: 1. Age at diagnosis: patients(75/108) were before 10 years old, but about one third of patients(33/108) were over 10 years old. 2. Sex distribution: M:F=1:2 3. Correlation between ventricular hypertrophy pattern by ECG and mean pulmonary arterial pressure: RVH : 57.2mmHg CVH : 42.6mmHg LVH : 25.6mmHg Normal : 20.4mmHg 4. Tall R, deep Q and peaked T in V6 were observed in 5.9% of the cases, tall R and deep Q in 14.7%, tall R and peaked T in 8.8%, tall R only in 41.2% and normal R in 29.4%. By increasing the Qp/Qs ratio, the more cases showed the left ventricular diastolic overloading pattern by Cabrera. |
