Final answer:
The question is asking about the difference in systolic pressure before experiencing symptoms. The specific threshold for symptom onset varies depending on the individual and the underlying health condition. It's important to consult with a healthcare professional for accurate information.
Step-by-step explanation:
The question is asking how much higher the systolic pressure should rise before experiencing symptoms (sx). The systolic pressure is the higher value and represents the maximum output of the heart during ventricular contraction. To determine the difference between the systolic pressure and the pressure at which symptoms occur, we need additional information about the specific medical condition or symptoms in question.
It's important to note that systolic blood pressure above 120 mm Hg is generally considered elevated and may indicate conditions like hypertension. A normal adult blood pressure is usually around 120/80 mm Hg, where 120 is the systolic pressure. However, the relationship between systolic pressure and symptom occurrence depends on the individual and their overall health.
To accurately determine how much higher the systolic pressure should rise before experiencing symptoms, it's necessary to consult with a healthcare professional who can evaluate specific symptoms, medical history, and perform appropriate diagnostic tests.
