Novel mapping techniques for cardiac electrophysiology.
Because of its high success rate and low morbidity, radiofrequency (RF) catheter ablation has become first line treatment for many arrhythmias. In this procedure, one or more electrode catheters are advanced percutaneously through the vasculature to contact cardiac tissues. A diagnostic study is performed to define the arrhythmia mechanism, and subsequently an ablation catheter is positioned ad...
متن کاملCardiac electrophysiology of adenosine. Basic and clinical concepts.
A denosine is an endogenous nucleoside that has potent electrophysiologic effects.1-4 As an antiarrhythmic agent, adenosine has several unique properties: 1) it is an intermediate metabolite (Figure 1), 2) it has a very short half-life (less than 1.5 seconds), 3) its effects are mediated by specific membrane receptors coupled to guanine nucleotide binding proteins (G proteins), and 4) it has si...

D.C. Sigg et al. (eds.), Cardiac Electrophysiology Methods and Models, DOI 10.1007/978-1-4419-6658-2_2, © Springer Science + Business Media, LLC 2010 Abstract Cardiomyocytes are excitable cells that have the ability to contract after excitation; therefore, each heartbeat is an event of electrical–mechanical coupling. Cardiac electrical activity at different levels can be measured through variab...
متن کاملNew Optical Mapping Design and Automated Algorithms for Cardiac Electrophysiology
Optical mapping is an important tool for assessment of cardiac electrophysiology. We demonstrate a new system for quantification and measurement of electrophysiological parameters in isolated cardiac tissue. The system makes use of voltage sensitive fluorescent dyes that shift in spectral property in response to millivolt changes in potential across cell membranes. Automated analysis of the pix...
