New research suggests direct PPG signals are superior for wearable blood pressure monitoring

Two new research papers explore methods for estimating blood pressure using wearable sensors, focusing on photoplethysmography (PPG) and electrocardiography (ECG) signals. The first paper proposes a lightweight hybrid learning framework that combines single-beat PPG embeddings with physiological features for cuffless blood pressure estimation, achieving a mean absolute error of 4.02 mmHg for systolic and 1.79 mmHg for diastolic blood pressure. The second study, analyzing the MIMIC-III database, found that PPG signals have a stronger physiological correlation with blood pressure than ECG signals, suggesting that direct PPG-to-BP prediction pipelines are more effective for wearable devices, achieving British Hypertension Society Grade A performance.
