●● sodium channel
Answer: what do class I drugs primarily affect?
●● slope of phase 0 (depolarization speed)
,Answer: what do class 1 drugs effect on sodium channels primarily do?
●● Class 1A drugs
Answer: slow conduction velocity and increase refractoriness
●● Class 1B drugs
Answer: drugs that shorten refractory periods
●● Class 1C drugs
Answer: pronounced depressants on conduction velocity
●● class II drugs
Answer: What class antiarrhythmic are beta blockers
●● Class II Drugs (Beta Blockers)
Answer: Prevent catecholamine-mediated action on the heart, blocks
sympathetic nervous system cardiac effects (no effect on AP, decreases
sympathetic tone)

affect conduction velocity
