It was recently shown that supernormal conduction in the diseased His-Purkinje system is more common than previously thought, and is always associated with prolongation of refractoriness. To assess whether supernormal conduction could also occur in the accessory pathway of patients with ventricular pre-excitation, 21 patients with manifestly prolonged refractoriness in the accessory pathway wer...

Microelectrode techniques were used to investigate the effects of rate and rhythm changes upon the period of supernormal excitability during repolarization in isolated canine right and left bundle branch and Purkinje fibers. The same microelectrode was used for both intracellular stimulation and recording. Excitability curves (strength-interval curves) were measured as the minimum depolarizing ...

A supernormal phase of conduction between right and left atria was observed in the exposed hearts of anesthetized dogs. Interatrial conduction time of premature atrial responses was reduced by as much as 17% during the early phase of diastole, relative to the conduction interval of basic driven responses. The supernormal phase lasted from 60 to 140 msec and was greater at slower basic driving f...

The electrophysiological characteristics of the period of supernormal excitability and supernormal conduction were investigated in the isolated canine His-Purkinje system. Strength-interval curves were determined as the minimum transmembrane current required to bring the impaled fiber to threshold potential following a conducted action potential. During the period of supernormal excitability, 1...

The supernormal phase of conduction is a short period of paradoxically improved conduction which may occur during an early phase of the recovery cycle of cardiac conducting tissue. The situation is paradoxical, for the improved conduction occurs during a short critical early period, while later impulses are blocked or have greater conduction delays. The term is, in a sense, a misnomer since con...

We study a bijective map from integer partitions to the prime factorizations of integers that we call “supernorm” partition, in which multiplicities parts are mapped factors natural numbers. The supernorm is connected family maps define, suggests potential apply techniques partition theory identify and prove multiplicative properties integers. As an application “supernormal” mappings (i.e., per...
