WebJul 8, 2015 · 1 large block: 300 We know the “normal” heart rate is 60-100 (although some would argue that 50-90 is more accurate). Using 60-100 the normal heart rate should have 3-5 large blocks between R-waves. More than 5 large blocks is a bradycardia and fewer than 3 blocks is a tachycardia. Let’s say it doesn’t work out perfect.
