Can you tell me about classes i and ii antiarrhythmic medications (and digoxin)?

Anti arrhythmic meds: Our question is too broad to answer. Please refer to the following site to get all information: http://www.Cvpharmacology.Com/antiarrhy/vaughan-williams.Htm.

Vaughan-Williams: What you are referring to, i believe, is what is called the vaughan-williams classification (circa 1970) of anti arrhythmic drugs. Class i drugs block sodium channels on the cells, class ii drugs block beta-receptors, class iii drugs block potassium channels, and class IV drugs block calcium channels. Digoxin does not fit the vaughn-williams classification, as its properties are different still.
