Caption: Heart electrophysiology research. Scientist working with equipment used to study the effect of defibrillation waveforms on the ability to stop fibrillation - the dangerous and potentially fatal rapid irregular and unsynchronised contraction of the heart. This is part of research into the electrical activity of the heart as it relates to medical devices such as cardiac pacemakers and defibrillators. This involves studies of single and multiple cells, and the heart as a whole. Optical mapping of membrane potential is used to record the electrical activity and intracellular calcium dynamics as well as wave propagation.
