The Pulse Wave menu presents the AC Pulse Wave in varying combination with the Valsalva Wave and the Heart Rate.

The "Pulse Wave" is ultimately derived from the "Whole Valsalva Wave". The Whole Valsalva Wave is filtered to remove the slower respiratory component, producing an "AC coupled" view that is centered around an X axis of zero.

The "AC" Pulse Wave While Breathing "Coherently"

The above figure depicts the pulse rate increasing during inhalation and decreasing during exhalation. We also see pulse amplitude decreasing during inhalation and increasing during exhalation.

Pulse Wave Series

The Pulse Wave menu:

1. Pulse Wave (AC): This is the conventional view of the "AC coupled" Pulse Wave. The interval between pulses is referred to as the Inter-Beat Interval or "IBI". The amplitude of the pulse correlates with heart "output" vs. rate. However, when we are breathing slowly and deeply there is explicit correlation between rate and output, output increasing as rate decreases and output decreasing as heart rate increases. With Release 1.1, heart rate indicators are provided.

2. Pulse Wave (AC), Valsalva Wave (Whole): The AC Pulsewave in combination with the Whole V-Wave. Note their very precise alignment. However, the Valsalva Wave leads the AC Pulsewave slightly. This is because the AC Pulsewave is actually derived from the Whole Valsalva Wave.

3. Pulse Wave (AC), Valsalva Wave (Fast): This screen depicts the AC Pulse Wave and the Fast Valsalva Wave. Again, note their alignment.

4. Pulse Wave (AC), Heart Rate (Fast): This screen depicts the AC Pulsewave and the Fast Heart Rate. Here we can clearly see the relationship between Interbeat Interval (IBI) and Heart Rate, longer IBI being slower Heart Rate and shorter IBI being faster Heart Rate. We can also see that as IBI becomes longer, the amplitude of the pulse becomes greater, and as IBI becomes shorter pulse amplitude becomes smaller, pulse amplitude being a measure of heart "output" vs. rate.

5. Pulse Wave (AC), Valsalva Wave (Fast), Heart Rate (Fast): This screen depicts all three. They are time synchronous.
