“…It also characterizes a radial pulse signal from a novel pulse recording instrument and detects the percussion wave, tidal wave and dichrotic wave. This technique provides an objective approach to the ancient science of pulse diagnosis [1]. A correlation in these 2 signals will be established in a future study.…”

“…Nadi Yantra [1], the electro-mechanical setup is a system that comprises of three identical piezo-based sensors, amplifier and filter circuit, a mechanical set-up and a data acquisition system (BioPac's MP-150 TM ). It captures signals from the three precise positions (as defined in ancient Ayurvedic texts) of the radial artery.…”

“…In ancient medical system of Ayurveda, Unani and the traditional Chinese system of medicine, radial artery is known to provide information on the physiological state of the human body [3,4]. To validate the science of pulse based diagnosis and provide an objective approach to it, signals are captured from the three close yet precise positions of the radial artery and analyzed for detection of significant points of interest such as percussion peaks, tidal valleys and dichrotic peaks [1].…”

The purpose of this study is to apply and evaluate performance of wavelets and select an appropriate wavelet to detect the peaks and dicrotic notch from the waveform captured from infrared finger-tip Photoplethesmography (PPG) and detect the significant peaks and valleys from the signal captured from the radial artery. Accurate detection of dicrotic notch is important as it finds its usage in various medical applications viz. pulse oximeters, vascular diagnostics, digital beat-to-beat blood pressure measurement systems and autonomic function analyzers. The method was extended to detect points of interest in pressure signal from radial artery. Radial artery signals were captured from a robust system called 'Nadi Yantra' [1] developed for the validation of ancient method of non-invasive pulse diagnosis of ailments. The system uses piezoelectric based pressure system to capture the palpations from the radial artery. To characterize the signals, wavelets were applied and the percussion wave, tidal wave and dicrotic notch were detected. The techniques developed were executed on a set of 120 data samples from healthy subjects. Daubechies wavelet was found to be suitable for PPG and radial artery pulse analysis. Overall efficiency of 98.45% for PPG signal and 97.89% for radial artery signal was achieved.

“…Although the procedure is subjective and highly skill based, quite a few practicing physicians make a reasonably accurate diagnosis, verified and corroborated by pathological tests [1,2]. The present study, similar to [3,4,5,6,7] attempts to objectively explore and analyze the radial pulse signal obtained from along the radial artery, for exploring the temporal and spatial domain dynamics.…”

Objective analysis and interpretation of radial pulse signal has been attempted. Capacitance variation based sensing and instrumentation mechanism has been developed for pulse sensing and logging. Traditional Indian Medicine (TIM) perspective for humor identification has been attempted. Pulse signal of healthy individual analysed in dominant humor interval, display prominent changes in recurrence quantification measures for pulse amplitude variations. These marker results are observed to correlate strongly with those obtained for a group of healthy individuals in a dominant humor interval period. Recurrence quantification analysis can possibly help in arriving at inferences apparent to sense perception for a TIM physician. General Terms BiomedicalSignal Processing, Traditional Indian Medicine(TIM) -Ayurveda.
