Bioimpedance Spectroscopy [PDF]

, 2011
In the context of biology, electrical phenomena are usually identified with ionic currents through protein channels, for example as they are postulated during nerve signalling (Andersen et al. Prog Neurobiol 88(2):104–113, 2009; Sakmann and Neher Annu Rev Physiol 46:455–472, 1984).

Possibilities in the application of machine learning on bioimpedance time-series

Journal of Electrical Bioimpedance, 2019
The relation between a biological process and the changes in passive electrical properties of the tissue is often non-linear, in which developing prediction models based on bioimpedance spectra is not trivial.

Assessment of Growth in Cardio‐Facio‐Cutaneous Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cardio‐facio‐cutaneous (CFC) syndrome is a rare, multiple congenital anomaly disorder in which individuals commonly experience faltering growth; however, systematic analysis of growth parameters in this disorder has not been performed. We recruited 69 participants with CFC through CFC International and collected data on assessing height ...

New Method for Predicting Efficiency of Heating by Measuring Bioimpedance during Radiofrequency Catheter Ablation in Humans [PDF]

, 2009
Introduction: Efficiency of heating (defined as the average temperature divided by the average power) during radiofrequency (RF) catheter ablation (RFCA) can be predicted by the electrode-tissue contact pressure before RFCA.
