This report details a rare case of U wave alternans in a patient with unstable angina and heart failure. This electrocardiogram finding, without QRS complex changes, is exceptionally uncommon.

Area of Science:

  • Cardiology
  • Clinical Electrophysiology

Background:

  • Unstable angina and heart failure are significant cardiovascular conditions.
  • Electrocardiogram (ECG) abnormalities are crucial for diagnosis and management.
  • U wave alternans is a rare ECG phenomenon.

Observation:

  • A patient with known heart failure and unstable angina presented with marked U wave alternans on ECG.
  • The U wave alternans were observed without any concurrent changes in the QRS complex.

Findings:

  • The co-occurrence of U wave alternans and unstable angina in a heart failure patient is extremely rare.
  • This specific ECG pattern highlights a unique electrophysiological manifestation.

Implications:

  • Understanding rare ECG findings like U wave alternans is vital for accurate diagnosis in complex cardiac patients.

  • Further research into the mechanisms and clinical significance of U wave alternans is warranted.
  • This case contributes to the limited literature on U wave alternans, aiding clinical recognition.
