Typical and atypical arterial pulse waveforms (APW). (a) Indicating systolic peak (SP), dicrotic notch (DN) and diastolic peak (DP). (b) Arterial pulse wave grading system46. PAD Grade A is attributed to an APW with a prominent dicrotic notch and sharp systolic peak; Grade B to an APW in which the dicrotic notch has disappeared; in a Grade C APW, the dicrotic notch is absent, the systolic peak is flattened, the upslope and downslope time are decreased and almost equal. In the most severe PAD cases, Grade D, the APW amplitude is significantly decreased, upslope and downslope times are equal, or the pulse is absent. Adapted from54.
