Supraventricular Tachycardia (SVT) Symptoms and Explanation

Introduction

Supraventricular tachycardia (SVT) is a condition where the heart beats faster than normal due to improper electrical activity above the ventricles. It commonly affects young and otherwise healthy individuals, but can also be seen in older adults with underlying heart conditions.

Key Symptoms of SVT

SVT episodes can vary in duration and frequency. Symptoms may include: - Palpitations: A sensation of rapid, fluttering, or pounding heartbeats. - Dizziness or Lightheadedness: Due to reduced blood flow to the brain. - Shortness of Breath: As the heart struggles to pump effectively. - Chest Discomfort or Pain: This can range from mild to severe. - Fatigue: Caused by the increased heart rate and reduced oxygen distribution. - Sweating: Due to the hyperactive state of the cardiovascular system. - Fainting (Syncope): In severe cases, due to sudden drops in blood pressure.

When to Seek Medical Help

  • If symptoms last longer than a few minutes or occur frequently.
  • If you experience chest pain, fainting, or severe dizziness.
  • If you have a history of heart disease and develop new symptoms.

Diagnosis and Treatment

  • Electrocardiogram (ECG): To detect abnormal heart rhythms.
  • Holter Monitoring: To capture irregular episodes over 24-48 hours.
  • Vagal Maneuvers: Techniques like the Valsalva maneuver may help stop an episode.
  • Medications: Beta-blockers or calcium channel blockers may be prescribed.
  • Catheter Ablation: A procedure that can permanently correct recurrent SVT.

Lifestyle and Prevention

  • Avoid excess caffeine and alcohol.
  • Manage stress with relaxation techniques.
  • Stay hydrated and maintain a balanced diet.
  • Learn vagal maneuvers to manage episodes when they occur.

Conclusion

SVT is not usually life-threatening, but it can significantly impact quality of life. If you experience symptoms, it is important to seek medical advice for proper diagnosis and management.
