Figure 2. Cardiovascular Outcomes.
A, Clinical outcomes among patients with Marfan syndrome. B, Atrial arrhythmia observed during 24-hour Holter monitoring. Atrial ectopy was defined as more than 10 premature atrial complexes per hour, and an atrial run was defined as 3 or more consecutive premature atrial beats at a rate of more than 100 beats per minute. C, Ventricular arrhythmia observed during 24-hour Holter monitoring. Ventricular ectopy was defined as more than 10 premature ventricular complexes per hour, and nonsustained ventricular tachycardia (NSVT) was defined as 3 or more consecutive premature ventricular beats at a rate of more than 100 beats per minute. MAD indicates mitral annular disjunction; SCD, sudden cardiac death; and VT, ventricular tachycardia.
