The voltage clamp and cardiac electrophysiology.

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...

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...

Analysis of cardiac pacemaker potential using a "voltage clamp" technique.

VASSALEE, MARIO. Analysis of card& pacemaker potential using a %ltage clamf3 technique. Am. J. Physiol. 210(6): 1335-1341. I g66.-Diastolic depolarization was studied by means of ccvoItage clamp” technique in short mammalian Purkinje fibers. Clamping the membrane potential at the maximal diastolic value resulted in an inward current rising with a time constant of 3 set in 5.4 mM K, indicating t...

Automated voltage-clamp technique.

The voltage-clamp electrophysiology method is the gold standard for measuring the function of ion channels. In the past, this technique has had limited applicability in pharmaceutical drug discovery because of its low throughput, steep learning curve, and challenges in standardization of the experiments. Recently, new electrophysiology platforms have been developed, which are based on the use o...
