Artificial Intelligence Enhances Diagnostics Using Photoplethysmography (PPG) Beyond Basic Measurements

A new review published on September 15, 2026, in MDPI highlights emerging applications of AI-based photoplethysmography (PPG) in cardiovascular and other medical diagnostics. While PPG is commonly used for heart rate and oxygen saturation, its waveform contains additional physiological information that AI can analyze to provide insights beyond traditional measurements. This development represents a significant scientific advance in non-invasive medical diagnostics.
