Heart rate is really important for how well our heart pumps blood. The amount of blood the heart pumps in one minute is called cardiac output.
Let’s break it down:
What is Cardiac Output?
Cardiac output (CO) is the total amount of blood the heart pumps. You can think of it like this:
CO = Stroke Volume (SV) × Heart Rate (HR).
How Heart Rate Affects It:
When your heart rate (HR) goes up, cardiac output (CO) can go up too, as long as the stroke volume (SV) stays the same.
This is super important when you’re exercising or feeling stressed. Your body needs more oxygen, so the heart works harder.
Finding the Right Balance:
But if your heart beats too fast, it might not fill up with blood properly. That means stroke volume (SV) might go down.
So, there’s a perfect heart rate where cardiac output (CO) works best.
In simple terms, heart rate is a big part of how our heart and body adjust to what we need!
