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.
