Intracardiac Conduction Intervals in Children with Congenital Heart Disease

چکیده
His bundle electrograms were recorded in 348 patients aged 2 months to 24 years following routine diagnostic cardiac catheterization. Among 41 children found to be free of anatomic or hemodynamic abnormality the following mean values were obtained: P-H interval, 93.4 ± 15.3 msec; P-A time, 21.2 ± 7.1 msec; A-H interval, 72.2 ± 15.9 msec; and H-V interval, 39.8 ± 5.2 msec. The remaining 307 patients were analyzed by diagnosis of congenital heart disease. The mean P-H interval was found to be significantly increased in both ostium primum and secundum atrial septal defect

Evaluation of QRS, QTC, JTC Intervals in Congenital Heart Disease with Pulmonary
BackgroundPulmonary hypertension (PH) in congenital heart disease (CHD) affects the patient prognosis. QRS and QTC intervals prolongation in ECG may exaggerate life-threatening dysrhythmia in these patients. We aimed to investigate the correlation between QRS, QTC and JTC intervals prolongation in ECG with PH in CHD children. Materials and MethodsIn a cross-sectional study tha...
