An automatic cardiac action potential duration meter
American Journal of Physiology-Heart and Circulatory Physiology, 1979 The duration of a cardiac action potential (AP) is measured from the beginning of its upstroke to the end of its asymptotic repolarization phase: the end being given by a point in proportion to the AP amplitude. If the resting potential, AP amplitude, as well as the duration, alter simultaneously, frequent accurate measurements can be extremely ...

Membrane Potential Dependent Duration of Action Potentials in Cultured Rat Hippocampal Neurons
Cellular and Molecular Neurobiology, 2007(1) Fluctuations of the membrane potential states are essential for the brain functions from the response of individual neurons to the cognitive function of the brain. It has been reported in slice preparations that the action potential duration is dependent on the membrane potential states.

Determinants of motor unit action potential duration
Clinical Neurophysiology, 1999Motor unit action potential (MUAP) recordings are modeled by means of a single muscle fiber simulation program, to define two key subcomponents comprising the complete physiologic MUAP duration. A number of defining properties of these subcomponents are further developed.A single muscle fiber simulation program is utilized with various muscle fiber ...

Estimating Atrial Action Potential Duration from Electrograms
IEEE Transactions on Biomedical Engineering, 2009Electrogram analysis is important in clinical and experimental settings. Activation recovery interval (ARI) has been used to measure ventricular action potential duration (APD) but its suitability for the atria has not been addressed. Mapping of atrial repolarization may be especially important during nerve stimulation since large heterogenous APD ...

Motor unit action potential duration and muscle length
Muscle & Nerve, 1999Motor unit action potential (MUAP) components are investigated by means of single fiber computer simulations and clinical measurements. The single fiber simulations have essentially full bandwidth without noise, whereas the clinical measurements were made with a 3-10,000-Hz bandwidth utilizing approximately 1000 averages to reduce noise optimally ...

Effect of epinephrine on the duration of action potential of papillary muscles
Experientia, 1974Im Gegensatz zur Kontrollbedingung (Tyrodelosung 1.8 mM Ca, 31°C, Reizfrequenz 30/min) ruft Adrenalin 6×10−6 M im Ca-freien Milieu eine significante Verlangerung der Aktionspotenziale hervor. Die Zugabe von Ca2+ kehrt die Aktionspotenzialdauer mit voller Entwicklung der positiv inotropen Wirkung zu Ausgangswerten zuruck.
