Quizplus · Accepted Answer

Multifocal atrial tachycardia is most commonly associated with pulmonary disease, such as chronic obstructive pulmonary disease (COPD) or pulmonary embolism. Other potential causes include electrolyte imbalances, hypoxia, and certain medications such as theophylline. While cocaine, amphetamines, and caffeine can all cause tachycardia, they are not specifically associated with multifocal atrial tachycardia. Acute myocardial infarction may cause arrhythmias but is not specifically associated with multifocal atrial tachycardia. Digitalis toxicity is more commonly associated with other arrhythmias such as atrial fibrillation or atrioventricular block.
