On an automatic delineator for arterial blood pressure waveforms
TLDR
The presented delineator characterizes arterial blood pressure waveforms in a beat-by-beat manner, and firstly seeks the pairs of inflection and zero-crossing points, and then utilizes combinatorial amplitude and interval criteria to select the onset and systolic peak.About:

Hypertension Assessment via ECG and PPG Signals: An Evaluation Using MIMIC Database.
TL;DR: A novel hypertension management method based on arterial wave propagation theory and photoplethysmography (PPG) morphological theory was researched to explore the physiological changes in different blood pressure (BP) levels, and PPG features were shown to classify BP categories more accurately than PAT.
