What symptom may occur as a result of parasympathetic nervous system activity after an inferior wall myocardial infarction?

Chest pain
Nausea and vomiting
Pulmonary edema
Hypertension

The correct answer is: Nausea and vomiting

Nausea and vomiting are common symptoms that can occur as a result of increased parasympathetic nervous system activity, particularly following an inferior wall myocardial infarction. The inferior wall of the heart is supplied by the right coronary artery in most individuals, and when an infarction occurs in this region, it can stimulate the vagus nerve, which is responsible for parasympathetic control of various bodily functions. This stimulation can lead to gastrointestinal symptoms, including nausea and vomiting, due to the connection between the heart and the gastrointestinal system. In the context of an inferior wall myocardial infarction, the vagal reflex is often heightened, causing increased parasympathetic tone. This can lead to a reduction in heart rate and other autonomic responses, including those affecting the digestive system. Understanding the role of the parasympathetic nervous system in relation to cardiac events is crucial for recognizing potential complications and managing symptoms effectively.
