(katzung, pp 426, brunton, pp 377)
most local anesthetics can block na+ channels in cardiac muscle and thus they can depress
automaticity and conduction. at very high doses they can also depress contractility, likely by
blocking
Which ion channel blockage does the primary mechanism of action of local anesthetics involves?
Inactivated, voltage-gated, Na+ channels
