Ashman beats are described as wide complex QRS complexes that follow a short R-R interval preceded by a long R-R interval. [3] This short QRS complex typically has a right bundle branch block morphology and represents an aberrantly conducted complex that originates above the AV node, rather than a complex that originates in either the right or left ventricle.
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
In the context of atrial fibrillation, the Ashman phenomenon is a form of aberrancy. Aberrancy is due to prematurity in which part of the conduction system is still refractory and cannot conduct the premature depolarization. This effect can sometimes be seen in the setting of a faster heart rate (tachycardia) and so is termed "rate-related ...
When V-tach is sustained (lasts for at least 30 seconds), inadequate blood flow to heart tissue can lead to cardiac arrest. [ 63 ] Bradyarrhythmias occur following dissociation of spontaneous electrical conduction and the mechanical function of the heart resulting in pulseless electrical activity (PEA) or through complete absence of electrical ...

"Widsith" (Old English: Wīdsīþ, "far-traveller", lit. "wide-journey"), also known as "The Traveller's Song", [1] is an Old English poem of 143 lines. It survives only in the Exeter Book ( pages 84v–87r ), a manuscript of Old English poetry compiled in the late-10th century, which contains approximately one-sixth of all surviving Old ...
As a term for the combination of the very high with the very low, bathos was introduced by Alexander Pope in his essay Peri Bathous, Or the Art of Sinking in Poetry (1727). ). On the one hand, Pope's work is a parody in prose of Longinus's Peri Hupsous (On the Sublime), in that he imitates Longinus's system for the purpose of ridiculing contemporary poets, but, on the other, it is a blow Pope ...
