Abstract

Chapter 5 discussed different algorithms that might be used to detect cardiology related waveforms. The sequence of time intervals between the detected waveforms can be used to calculate the rate of the cardiac cycle. Cardiac rates are typically expressed as the number of beats per minute or as an average cycle length – the time interval between consecutive beats. These are reciprocally related: Rate (in beats/min) = 60 divided by average cycle length (in seconds)

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
