心血管疾病（CVD）已成为人类健康的最大威胁，高血压加速了CVD的发生。避免心血管疾病并发症的最佳方法是在早期阶段管理和预防高血压。然而，大多数类型的高血压，特别是高血压前期，根本没有症状。高血压的知晓率和控制率极低。本研究基于动脉波传播理论和光电容积描记（PPG）形态学理论，探讨了不同血压水平下的生理变化，提出了一种新的高血压管理方法。从心电图（ECG）和光电容积图（PPG）信号中提取脉冲到达时间（PAT）和光电容积图（PPG）特征，分别代表动脉波传播理论和PPG形态学理论。使用三个特征集（一个仅包含PAT，一个仅包含PPG特征，一个包含PAT和PPG特征）对不同的BP类别进行分类，定义为正常血压、高血压前期和高血压。PPG特征被证明比PAT更准确地分类BP类别。此外，PAT和PPG相结合的功能，提高了BP分类性能。正常血压与高血压前期的F1值为84.34%，正常血压与高血压的F1值为94.84%，正常血压+高血压前期与高血压的F1值为88.49%。这表明ECG和PPG信号的同时收集可以检测高血压。
Cardiovascular diseases (CVDs) have become the biggest threat to human health, and they are accelerated by hypertension. The best way to avoid the many complications of CVDs is to manage and prevent hypertension at an early stage. However, there are no symptoms at all for most types of hypertension, especially for prehypertension. The awareness and control rates of hypertension are extremely low. In this study, 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. Pulse Arrival Time (PAT) and photoplethysmogram (PPG) features were extracted from electrocardiogram (ECG) and PPG signals to represent the arterial wave propagation theory and PPG morphological theory, respectively. Three feature sets, one containing PAT only, one containing PPG features only, and one containing both PAT and PPG features, were used to classify the different BP categories, defined as normotension, prehypertension, and hypertension. PPG features were shown to classify BP categories more accurately than PAT. Furthermore, PAT and PPG combined features improved the BP classification performance. The F1 scores to classify normotension versus prehypertension reached 84.34%, the scores for normotension versus hypertension reached 94.84%, and the scores for normotension plus prehypertension versus hypertension reached 88.49%. This indicates that the simultaneous collection of ECG and PPG signals could detect hypertension.
