Evaluation on peripheral arterial occlusive disease with a new electrical impedance plethysmogram
Indian Journal of Thoracic and Cardiovascular Surgery, 1982A new impedance plethysmogram with a high signal to noise ratio was developed at Bhabha Atomic Research Centre, Bombay. 51 normal and 126 patients with arterial occlusive disease were studied. Assessment of distal run off was reliable. The findings correlated well with radiological observations.

Estimation of pulse arrival time using impedance plethysmogram from body composition scales
2015 IEEE Sensors Applications Symposium (SAS), 2015Long-term periodic monitoring of cardiovascular function in unobtrusive way has been a challenge in sensor research lately. This work presents the investigation of the method for pulse arrival time (PAT) estimation using body composition scales. It employs the electrocardiogram and the impedance plethysmogram (IPG) which are recorded from palm and ...

A study of arterial pressure plethysmograms and impedance plethysmograms
American Heart Journal, 1961Abstract 1.1. Comparison of contours of the following height-equalized pulses from the brachial artery has been made: (1) an intra-arterial pressure pulse versus an external pressure plethysmogram; (2) a pressure plethysmogram versus an impedance plethysmogram.

A microprocessor measurement system is developed for simultaneously capturing electrocardiography (ECG) and impedance plethysmogram (IPG) signals. All the measurement electrodes are coupled with human skin in a non-contact capacitive way. A capacitive coupled pickup circuit is used for obtaining the original ECG and IPG signals.

Electrical Impedance Plethysmogram in Peripheral Blood Flow
1991We have previously reported the results of experiments on electrical impedance plethysmography and electromagnetic flowmetry in the central caudal arteries of anesthetized rats. Although the theoretical formula we proposed was successfully applied, we did not clarify correlations between CR and mean blood flow obtained in other experiments.

Non-Invasive Monitoring for Cardiac Rejection Using Impedance Plethysmograms
1993Noninvasive monitoring of cardiac rejection has been the most challenging aspect of cardiac transplantation. Our previous study [1] revealed that the cardiac rejection originates in the right ventricle and shifts to the left ventricle. Therefore, it is possible that the wall motion of the right ventricle could have deteriorated at the initial stage of ...

The contribution of scalp blood flow to pulses obtained by cerebral electrical impedance plethysmography (rheoencephalography) has been investigated using a four-electrode (quadripolar) montage with brass disc electrodes 1 cm, 2 cm and 4 cm in diameter.

Problems in the Clinical Interpretation of Impedance Plethysmogram and Rheoencephalogram
1971It must be accepted that the clinical use of impedance plethysmography, and rheoencephalography (REG) in particular, remains controversial. Other participants in this Conference will doubtless discuss the safety factors which must be considered in the design and construction of equipment to be used in impedance plethysmography.
