The system is therefore sometimes known as the Singh-Vaughan Williams classification. 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.

Therefore, blocking β 2-adrenoceptors lowers plasma glucose. β 1-blockers have fewer metabolic side effects in diabetic patients; however, the fast heart rate that serves as a warning sign for insulin-induced low blood sugar may be masked, resulting in hypoglycemia unawareness. This is termed beta blocker-induced hypoglycemia unawareness ...
