Radial Pulse is a record of blood flow in the artery as sensed by electrical impedance plethysmography. Pulse morphology/pattern provides important clinical information to doctors for diagnosing wide range of diseases. The pulse morphology is seen to vary with respect to time in different individuals, also varies in multiple disease conditions, which results in struggle to estimate waveform accurately. Therefore, for early diagnose of diseases need to classify the different morphological patterns of peripheral pulse accurately. In this study, deep learning Convolutional Neural Network (CNN) models have been used for the recognition of radial pulse morphologies obtained from Peripheral Pulse Analyzer (PPA). Approximately 9000 images of fifteen different patterns of pulse waves are used for training and testing of three existing models of CNN namely VGG16, VGG19 and ResNet50. Confusion matrix parameters are calculated to assess each CNN model's performance. After testing the dataset, the highest accuracy of CNN VGG19 model is 92.13% and it has provided best result as compared with other two models.

摘要

Radial Pulse is a record of blood flow in the artery as sensed by electrical impedance plethysmography. Pulse morphology/pattern provides important clinical information to doctors for diagnosing wide range of diseases. The pulse morphology is seen to vary with respect to time in different individuals, also varies in multiple disease conditions, which results in struggle to estimate waveform accurately. Therefore, for early diagnose of diseases need to classify the different morphological patterns of peripheral pulse accurately. In this study, deep learning Convolutional Neural Network (CNN) models have been used for the recognition of radial pulse morphologies obtained from Peripheral Pulse Analyzer (PPA). Approximately 9000 images of fifteen different patterns of pulse waves are used for training and testing of three existing models of CNN namely VGG16, VGG19 and ResNet50. Confusion matrix parameters are calculated to assess each CNN model's performance. After testing the dataset, the highest accuracy of CNN VGG19 model is 92.13% and it has provided best result as compared with other two models.
