Radiation therapy can cause heart conduction problems, leading to syncope. A pacemaker successfully treated this rare complication in a 51-year-old man, highlighting effective management strategies.

Area of Science:

  • Cardiology
  • Oncology
  • Electrophysiology

Background:

  • Radiation therapy to the chest is a known risk factor for cardiac complications.
  • Conduction system disease can manifest insidiously following radiation exposure.
  • Understanding long-term sequelae of cancer treatment is crucial for patient management.

Observation:

  • A 51-year-old male presented with recurrent syncope.
  • Electrocardiogram revealed a significant pause, indicative of conduction abnormality.
  • Electrophysiology study confirmed a prolonged H-V interval.

Findings:

  • The prolonged H-V interval was directly attributed to prior chest radiation therapy.
  • This represents a rare instance of radiation-induced atrioventricular block.

  • The patient's syncope was a direct result of the cardiac conduction defect.

    • Implications:

    • Permanent pacemaker implantation is an effective treatment for radiation-induced conduction system disease.
    • This case underscores the importance of recognizing and managing delayed cardiac complications post-radiation.
    • Awareness of this rare complication can prevent misdiagnosis and ensure timely intervention for life-threatening arrhythmias.
