Final Answer:
The ECG findings of aortic coarctation may include left ventricular hypertrophy (LVH) and notched or delayed upstroke in the QRS complex.
Step-by-step explanation:
Aortic coarctation is a narrowing of the aorta, leading to increased pressure in the upper body and decreased pressure in the lower body. This condition often results in left ventricular hypertrophy (LVH) on an electrocardiogram (ECG) due to increased workload on the left ventricle. Additionally, a characteristic ECG finding in aortic coarctation is a notched or delayed upstroke in the QRS complex, reflecting the impact of increased afterload on the heart's electrical conduction.
It's important to note that while LVH is a common finding, the notched or delayed upstroke in the QRS complex is more specific to aortic coarctation, helping differentiate it from other causes of LVH.
