Supraventricular Tachycardia (SVT) - ICD-10 and Key Information
Introduction
Supraventricular tachycardia (SVT) is a condition where the heart beats abnormally fast due to faulty electrical signals from above the ventricles. It typically manifests as sudden episodes of rapid heart rate, which can last from a few minutes to several hours.
ICD-10 Code for SVT
The ICD-10 (International Classification of Diseases, 10th Edition) code for supraventricular tachycardia is I47.1 .
Causes and Risk Factors
SVT occurs due to abnormal electrical pathways in the heart. Some common triggers include: - Heart conditions , such as atrial fibrillation or pre-excitation syndromes - Stress and caffeine overuse - Electrolyte imbalances - Medications , such as decongestants or asthma drugs - Hyperthyroidism
Symptoms of SVT
- Palpitations (rapid heartbeat sensation)
- Dizziness or lightheadedness
- Shortness of breath
- Chest discomfort
- Fainting (in severe cases)
Diagnosis
Diagnosis is based on medical history, physical examination, and specific tests such as: - Electrocardiogram (ECG) *– Records the electrical activity of the heart - * Holter monitor – A portable device that captures prolonged ECG readings - *Electrophysiological study (EPS) * – Helps locate abnormal conduction pathways
Treatment Options
1. Emergency Management
- Vagal maneuvers (e.g., holding your breath, bearing down, or splashing cold water on the face)
- Medications , such as adenosine , beta-blockers , or calcium channel blockers
- Cardioversion (in severe cases)
2. Long-Term Management
- Lifestyle modifications (reducing stress, caffeine, and alcohol intake)
- Medications (if recurrent episodes occur)
- Catheter ablation (a procedure to destroy abnormal electrical pathways)
When to See a Doctor
Seek immediate medical help if you experience: - Severe chest pain - Loss of consciousness - Persistent rapid heart rate despite self-management
Conclusion
Supraventricular tachycardia is a manageable condition with proper diagnosis and treatment. If you experience symptoms, consult a cardiologist for a tailored management plan.
