Processing of blood pressure trace to get heart rate. Representative blood pressure data shown at the bottom were previously filtered at 100 Hz. The small fluctuations in blood pressure trace are highlighted to show individual heartbeats. To calculate heart rate, the blood pressure was bandpass filtered between 3 and 12 Hz (180–720 beats per minute (bpm)), the power spectral density was calculated, and the peak was determined every second to compute heart rate, reported in bpm (top chart).
