Biomedical Signal Analysis: A Case-Study Approach

I thank my students and readers of my book who indicated errors and parts that were not clear in the book; in particular, I thank Fábio Jose ́ Ayres, and Alexander Kalinichenko. 3 4Symbols and Abbreviations, p xxix: Add the following entries: BP: blood pressure PVC: premature ventricular contraction 5Section 1.2.1 The action potential, pp 5 – 9: Additional illustrations given in Figures 1 and 2. Excitable cell enclosed in a semipermeable membrane Selective permeability: some ions can move in and out of the cell easily, wheareas others cannot, depending upon the state of the cell and the voltage-gated ion channels.
