Graph: Heart Rate (X) vs. BP (Y)
This model is an upgrade from a simple linear relationship. It uses **Heart Rate (X)** and **Age** to calculate the **Predicted Blood Pressure (Y)**. Age acts as a moderating variable that subtly shifts the entire baseline prediction.
The Model:
$Y = 120 + (0.15 \times \text{HR}) - (0.1 \times \text{Age})$
- $0.15$: Represents the increase in BP for every one-unit increase in Heart Rate.
- $-0.1$: Represents a subtle negative age-related factor applied to the baseline.
- $C_{\text{Dynamic}}$: The Y-intercept ($120 - 0.1 \times \text{Age}$) is dynamic, meaning the predicted line shifts based on your input age.
Heart rate and blood pressure are related, but not in a simple, one-to-one way. When heart rate increases (like during exercise), blood pressure often rises because the heart is pumping more blood. However, the brain can also signal for an increased heart rate to compensate for low blood pressure, creating an inverse relationship. Moreover, both can be affected independently by factors like genetics, diet, stress, and certain medications.
- Increased heart rate can increase blood pressure: When your heart beats faster, it pumps more blood per minute, which can cause blood pressure to rise.
- Low blood pressure can increase heart rate: If blood pressure drops, the body's response is often to increase heart rate to ensure that oxygen-rich blood can still reach all organs and tissues, including the brain.
- High blood pressure can increase heart rate: Chronically high blood pressure forces the heart to work harder, which can sometimes lead to a higher heart rate over time.
