“…14 In addition to heart rate variability studied worldwide, few researchers have studied blood pressure variability and peripheral blood flow variability. 79 Changes in the morphology of the peripheral pulse were noticed during these studies and different methods were tried to quantify the morphological changes 10,11 with a yield of 80 to 90%.…”

“…Karamchandani et al 10,11 have tried several methods for auto matic identification of these patterns including dynamic time warping, parallel support vector, etc. Classi fication of these waveforms using dynamic time warping yielded an accuracy of more than 94%, efficient predictive values, and statistics evaluating measures such as MCC and kappa MGMJMS met partial success.…”

Based on the past observation of recording abnormal impe dance cardiogram (ICG) in 13% normal subjects and subse quent detection of coronary artery disease (CAD) in majority of these cases, led the authors to record peripheral impedance plethysmograms (IPG) in control subjects and patients using impedance cardiovasograph, developed by electronics division, Bhabha Atomic Research Centre (BARC). Analysis of peripheral plethysmograms, thus recorded, has shown 8 dominant morphological patterns of the peripheral pulses depending upon their status of health. In cognizance of these observations, different methods of pattern analysis were used for pattern identification. Fourier Transform based method has been observed to yield higher diagnostic yield. Morphology index (MI) of the peripheral pulse derived from this method was observed to vary from 0.28 to 1, the former indicating the poorest and later the normal health. Among 100 subjects suffering from various disorders, 8 patients with coronary artery disease have recorded average index to be between 0.30 and 0.45.
