Overview

Electrocardiographic findings on cardiac myxoma are nonspecific.[1]

Key EKG Finding in Myxoma

  • Electrocardiographic findings on cardiac myxoma are nonspecific and often normal.[2]
  • EKG may reflect the hemodynamic alterations that result from tumor size, such as atrial overload or ventricular hypertrophy.[1]
  • Moreover, cardiac rhythm tends to be normal sinus (NSR) and atrial fibrillation is uncommon.
  • According to tumor location, long-term electrocardiographic monitoring may demonstrate supraventricular arrhythmias in atrial tumors and ventricular arrhythmias in ventricular tumors.[1]
