Wilders ‘ Dynamic clamp ’ in cardiac electrophysiology

Dynamic clamp: a powerful tool in cardiac electrophysiology.

Dynamic clamp is a collection of closely related techniques that have been employed in cardiac electrophysiology to provide direct answers to numerous research questions regarding basic cellular mechanisms of action potential formation, action potential transfer and action potential synchronization in health and disease. Building on traditional current clamp, dynamic clamp was initially used to...

The voltage clamp and cardiac electrophysiology.

• Although voltage clamp methods have been applied experimentally to cardiac tissue for over a decade, this field of study has failed to achieve general acceptance because of limitations of the experimental approach and difficulty in interpreting the results. Yet this technique is valuable within its limitations, and to dismiss it would be to lose a valuable tool. In perspective, most technique...

Structural Defects Lead to Dynamic Entrapment in Cardiac Electrophysiology

Biological networks are typically comprised of many parts whose interactions are governed by nonlinear dynamics. This potentially imbues them with the ability to support multiple attractors, and therefore to exhibit correspondingly distinct patterns of behavior. In particular, multiple attractors have been demonstrated for the electrical activity of the diseased heart in situations where cardio...

Cardiac Electrophysiology

Recently, significant achievements have beenmade in cardiac electrophysiology research, including Ca regulatory pathways, membrane ion channel-related intracellular signaling, and electrical remodeling in cardiomyopathies. The rapid progress in the basic research has led to applications of numerous new methods and strategies to clinical diagnoses and treatments. The efficacy of antiarrhythmic p...
