TL;DR: The objective of the study was to establish an experimental procedure and show direct AFM results that unequivocally can be assigned as “Neuromuscular Junction Stimulation,” and establish a protocol for further studies to determine the exact levels of AFM.
Journal ArticleDOI
Extracellular potentials related to intracellular action potentials during impulse conduction in anisotropic canine cardiac muscle.
TL;DR: The implications of the analysis are considerable, since the gratifying agreement between the theoretical and measured results indicates that the details of the extracellular waveforms can be explained on the basis of the distribution of intracellular currents; i.e.,extracellular potentials provide a sensitive index of intrACEllular current flow.
Journal ArticleDOI
Relating Epicardial to Body Surface Potential Distributions by Means of Transfer Coefficients Based on Geometry Measurements
TL;DR: A method for finding transfer coefficients that relate the epicardial and body surface potential distributions to each other is provided, based on knowing the geometric location of each electrode, and on having enough electrodes to establish the geometric shape and the potential distribution of closed epicardials and body surfaces.
Journal ArticleDOI
Electrophysiological Effects of Remodeling Cardiac Gap Junctions and Cell Size Experimental and Model Studies of Normal Cardiac Growth
TL;DR: The results suggest that in pathological substrates that are arrhythmogenic, maintaining cell size during remodeling of gap junctions is important in sustaining a maximum rate of depolarization.
