Summary

Electrocardiographic (ECG) changes are common after heart transplantation, often presenting as conduction disorders. Advanced ECG monitoring may detect subtle rejection signs missed by standard tests.

Area of Science:

  • Cardiology
  • Transplant Medicine
  • Electrophysiology

Context:

  • Electrocardiographic (ECG) changes occur in nearly 75% of heart transplant recipients.
  • Early postoperative findings include conduction disorders, necessitating pacemakers in 3-5% of cases.
  • Bundle branch block is the most common persistent disorder, significant only if progressive.

Purpose:

  • To review the spectrum of electrocardiographic (ECG) changes following heart transplantation.
  • To correlate ECG findings with specific postoperative complications and graft status.
  • To highlight the diagnostic utility of ECG in identifying acute rejection and other adverse events.

Summary:

  • Conduction disorders are frequent early post-transplant findings, with bundle branch block being the most common persistent issue.

  • Postoperative atrial fibrillation/flutter is less common than post-other cardiosurgery and may indicate acute rejection.
  • Ventricular arrhythmias often signal advanced graft coronary disease and are linked to sudden cardiac death. Pre-cyclosporin A, reduced QRS voltage indicated rejection; now, only severe rejection causes ECG changes, with intracardiac electrograms needed for early detection.

    • Impact:

    • Understanding these ECG patterns aids in early diagnosis and management of heart transplant complications.
    • Improved recognition of ECG changes can lead to timely intervention for graft dysfunction and rejection.
    • This review provides a comprehensive overview for clinicians managing heart transplant recipients, emphasizing the evolving role of ECG in monitoring graft health.
