Timing aspects of the intracranial and arterial pressure waveforms. Single-pulse intracranial and arterial blood pressure waveforms, showing the elements of pulse wave timing. Timing can either be calculated intrinsically within the intracranial pulse wave, such as with the systolic/diastolic timing difference (dT) or the slope of intracranial pulse wave (dP/dT), or it can be measured relative to a reference pulse wave, such as the latency between the peaks of the ICP and the ABP waves.
