Answers

1. ANSWER: D. The M-mode tracings show an atrial flutter with two atrial contractions for every ventricular contraction. Treatment is recommended for sustained arrhythmia or evidence of hydrops (Fig. 6.46). Digoxin is usually first-line agent if no hydrops present with case series reports of 60% to 80% positive responders. Other agents used in the treatment of atrial flutter include flecainide, sotalol, and amiodarone. 1
