Q

procainamide hydrochloride expected effect

A

depress excitability of cardiac muscle to electrical stimulation and slows conduction in atrium, bundle of His, increases refractory period.

Sodium channel blocker, slowing conduction sodium ions thru sodium channels. Blocking these channels slows conductivity & prolongs action potential & refractory period. Result is decrease excitability and impulse conduction of atria & ventricles
