Final Answer:
Common signs of high-grade aortic stenosis during exercise include dyspnea, angina, and syncope, but seizures are not typically associated with this condition. The correct answer is C. seizure.
Step-by-step explanation:
Common signs of high-grade aortic stenosis during exercise typically include dyspnea (A), angina (B), and syncope (D). Dyspnea, or shortness of breath, occurs due to the increased workload on the heart, as it struggles to pump blood through the narrowed aortic valve. Angina, chest pain or discomfort, is a result of the inadequate supply of oxygen to the heart muscle. Syncope, fainting or loss of consciousness, can happen when the heart is unable to meet the increased oxygen demands during exercise. Seizures (C) are not typically associated with aortic stenosis during exercise, making option C the exception.
Understanding the symptoms associated with aortic stenosis is crucial for prompt diagnosis and intervention. During exercise, the heart's demand for oxygen-rich blood increases, exacerbating the impact of a narrowed aortic valve. Dyspnea, angina, and syncope are indicative of the heart's compromised ability to meet this demand. However, seizures are not a common manifestation of aortic stenosis during exercise. Recognizing these symptoms aids healthcare professionals in assessing the severity of the condition and determining appropriate management strategies, which may include medical treatment or surgical intervention to repair or replace the aortic valve.
