The five main classes in the Vaughan Williams classification of antiarrhythmic agents are: Class I agents interfere with the sodium (Na +) channel. Class II agents are anti-sympathetic nervous system agents. Most agents in this class are beta blockers. Class III agents affect potassium (K +) efflux. Class IV agents affect calcium channels and ...
Class of medications that are competitive antagonists that block the receptor sites for the endogenous catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline) on adrenergic beta receptors, of the sympathetic nervous system.

This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
Pharmacological cardiotoxicity is defined as cardiac damage that occurs under the action of a drug. This can occur both through damage of cardiac muscle as well as through alteration of the ion currents of cardiomyocytes. [1] Two distinct drug classes in which cardiotoxicity can occur are in anti-cancer and antiarrhythmic drugs.
ATC code C01 Cardiac therapy is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
Sodium channel blockers (1 C, 77 P) Pages in category "Antiarrhythmic agents" The following 59 pages are in this category, out of 59 total.
Class Ic antiarrhythmic agents markedly depress the phase 0 depolarization (decreasing V max). They decrease conductivity, but have a minimal effect on the action potential duration. Of the sodium channel blocking antiarrhythmic agents (the class I antiarrhythmic agents), the class Ic agents have the most potent sodium channel blocking effects.
