What does it mean if your heart rate is above 120 while inactive?

When your heart beats more than 100 times a minute at rest, that's tachycardia. Because your heart beats too often, it doesn't have the time it needs to fill with blood between beats. This can be dangerous if your heart can't supply all of your cells with the blood and oxygen they need.
