Derived count rate

WebDerived rates require an active Advanced Rates add-on! The derived rates allow for more flexible prices based on your standard rates. Derived rates calculate their prices by adding or subtracting amounts (Derived Amount rate) or percentage (Derived Percent Rate) to/from an existing standard rate.

WebJan 9, 2024 · Rate = Number of R waves (rhythm strip) X 6 The number of complexes (count R waves) on the rhythm strip gives the average rate over a ten-second period. This is multiplied by 6 (10 seconds x 6 = 1 minute) to give the average beats per minute (bpm) Useful for slow and/or irregular rhythms WebIf the above function is estimated for many measured intervals with various values of D subtracted (and for various values of n) it should be found that for values of D above a certain threshold, the above equation will be nearly true, and the count rate derived from these modified intervals will be equal to the true count rate.
