Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.
Rhythms produced by an ectopic focus in the atria, or by the atrioventricular node, are the least dangerous dysrhythmias; but they can still produce a decrease in the heart's pumping efficiency because the signal reaches the various parts of the heart muscle with different timing than usual and can be responsible for poorly coordinated contraction.
R-peak time for right ventricle is measured from leads V1 or V2, where upper range of normal is 35 ms. R wave peak time for left ventricle is measured from lead V5 or V6 and 45 ms is the upper range of normal. [7] R wave peak time is considered to be prolonged if it's more than 45 ms.
Dysrhythmia may refer to: Circadian dysrhythmias , disturbances of circadian (daily) rhythms including jet lag and disturbed sleep timing Cardiac dysrhythmia , a medical condition causing irregular heart rate, also called arrhythmia
Kerrang! gave the album a generally positive review. "Throughout the six tracks, there's richness of sound that throws a nod in the direction of Don Caballero, but they are capable of utterly kicking you arse when they want to with rushes of percussive violence and frantically mangled guitar, occasionally delving into the kind of assonance that makes your teeth hurt," reviewer Dan Slessor ...
