Ans: C
Feedback:
The development of a new arrhythmia due to drug administration is referred to as a proarrhythmic effect. Cinchonism refers to quinidine toxicity. Refractory period refers to the quiet period between the transmission of nerve impulses along a nerve fiber. Action potential refers to the electrical impulse that passes from cell to cell in the myocardium of the heart and stimulates the fibers to shorten, causing heart muscles to contract.
