Cardiac Question #24


The nurse caring for a client with dilated cardiomyopathy is scheduling a transthoracic echocardiogram, which might reveal what type of finding associated with the diagnosis?


  1. Decreased ejection fraction
    • Rationale:
  2. Decreased heart rate
    • Rationale:
  3. Presence of bundle branch block
    • Rationale:
  4. Asymptomatic ventricular tachycardia
    • Rationale:



Echocardiographic indicators that help diagnose and provide prognosis include left ventricular size and systolic function through ejection fraction among other results including right ventricular function, valve regurgitation function, left atrial volume index, and may include contractile reserve results when used with dobutamine stress echo. Echocardiograhic indicators do not rely on decreased heart rate, presence of bundle branch block or other heart irregularity such as V-tach for diagnostic consideration for dilated cardiomyopathy.
