Final answer:
The most common arrhythmia associated with inferior wall MI is bradycardia, typically treated with beta blockers or anti-arrhythmic agents. Intravenous fluids are recommended for persistent hypotension due to volume depletion.
Step-by-step explanation:
Bradycardia is the most common arrhythmia seen in association with inferior wall MI. Patients should be treated with beta blockers or anti-arrhythmic agents such as procainamide to restore a normal heart rhythm, especially when there are severe symptoms of arrhythmia. If persistent hypotension occurs, which usually is a sign of volume depletion, intravenous fluids should be administered to correct the volume status.
