Electrocardiogram
Electrocardiogram
- Ocasionally,the ECG is normal in the newborn , but in older patients there is RAD and RVH.
- After a Mustard operation there are bradyarrhythmias.
- The right axis deviation is moderate or absent, in patients with a large VSD, low pulmonary vascular resistance, and LV volume overload.
- The right axis deviation is greater if there is a reduced pulmonary arterial blood flow and reduced left ventricular volume as a result of pulmonary vascular disease or pulmonic stenosis.
