Swallowing can trigger supraventricular tachycardia (SVT) in some individuals. Amiodarone is effective in preventing these swallowing-induced tachyarrhythmias, particularly hyperkinetic types.

Area of Science:

  • Cardiology
  • Gastroenterology
  • Clinical Medicine

Background:

  • Supraventricular tachycardia (SVT) is an abnormal heart rhythm.
  • While vagal inhibition explains some SVT, hyperkinetic arrhythmias are less understood.
  • Esophageal stimulation can influence cardiac function.

Observation:

  • A 51-year-old patient experienced recurrent SVT episodes triggered by swallowing.
  • This case presented as a predominantly hyperkinetic arrhythmia.
  • Literature review revealed fewer cases of hyperkinetic SVT compared to hypokinetic types.

Findings:

  • The patient's SVT was linked to sympathetic esophageal fibers and cardiac nerves.
  • Amiodarone demonstrated significant efficacy in preventing swallowing-induced tachyarrhythmias.

  • This suggests a sympathetic pathway involvement in specific SVT cases.

    • Implications:

    • Understanding the link between esophageal function and cardiac arrhythmias is crucial.
    • Amiodarone may be a primary treatment for swallowing-induced SVT.
    • Further research into the sympathetic nervous system's role in SVT is warranted.
