The potentiation of the Ca transient is accompanied by an increase in the action potential duration.
As expected, application of IKur blocker produced pronounced action potential duration (APD) prolongation in atrial myocytes.
From experiments, we know that the heterogeneity of action potential duration and morphology is an important mechanism of ventricular tachyarrhythmia.
At the biventricular level, we reduced the apex-to-base and transmural gradients of action potential duration (APD).
Options under discussion include an air campaign, using either or both air force or navy warplanes, the potential duration of which has yet to be determined.
Hondeghem, L. M., Carlsson, L. & Duker, G. Instability and triangulation of the action potential predict serious proarrhythmia, but action potential duration prolongation is antiarrhythmic.
Margolis, E. B., Mitchell, J. M., Ishikawa, J., Hjelmstad, G. O. & Fields, H. L. Midbrain dopamine neurons: projection target determines action potential duration and dopamine D2 receptor inhibition.
The simulated action potential duplicates the experimentally observed effects of changes in [K]o on action potential duration and rest potential.
Parameters were simultaneously fitted to action potential (AP) morphology, action potential duration (APD) restitution and conduction velocity (CV) restitution curves in these patients.
Electrophysiological parameters, such as the action potential duration (APD), rates of depolarization and repolarization and beating frequency were assessed.
Class III antiarrhythmic agents selectively delay the effective refractory period (ERP) and increase the transmembrance action potential duration (APD).
