Paroxysmal Supraventricular Tachycardia: Causes & Treatment
Paroxysmal Supraventricular Tachycardia (PSVT) is a heart rhythm disorder that causes sudden episodes of rapid heart rate originating above the heart's ventricles. The primary impact of PSVT on health is the disruption it causes to the normal heart rhythm, potentially leading to symptoms and complications that affect overall well-being and quality of life.
What are the Symptoms of Paroxysmal Supraventricular Tachycardia
Paroxysmal Supraventricular Tachycardia (PSVT) typically presents with sudden episodes of rapid heart rate. It is essential to seek medical evaluation if you experience such symptoms to determine the underlying cause and receive appropriate treatment.
- Rapid heartbeat
- Palpitations
- Chest discomfort or pain
- Dizziness or lightheadedness
- Shortness of breath
- Fainting or nearfainting episodes

Get A Second OpinionCauses of Paroxysmal Supraventricular Tachycardia
Paroxysmal Supraventricular Tachycardia (PSVT) can be caused by various factors. Common causes include abnormalities in the heart's electrical system, such as extra electrical pathways or abnormal connections.
- Stress or anxiety
- Caffeine or nicotine consumption
- Overactive thyroid gland
- Heart conditions such as atrial fibrillation or heart failure
- Certain medications
- Alcohol consumption
- Electrolyte imbalances
- Structural heart abnormalities
Types of Paroxysmal Supraventricular Tachycardia
Paroxysmal Supraventricular Tachycardia (PSVT) encompasses various forms or types that affect the heart's electrical system. These different forms share the characteristic of rapid heart rate episodes originating above the heart's ventricles. While each type may have specific triggers or characteristics, they all result in sudden episodes of fast heartbeats.
- Atrial Fibrillation (AFib): AFib is the most common type of supraventricular tachycardia, characterized by irregular and rapid heartbeats originating in the atria.
- Atrial Flutter: Atrial flutter is a type of SVT where the heart's electrical signals circulate rapidly in the atria, leading to a fast and often regular heartbeat.
- Paroxysmal Atrial Tachycardia (PAT): PAT is a form of SVT with sudden episodes of rapid heart rate originating from abnormal electrical signals in the atria.
- Wolff ParkinsonWhite Syndrome (WPW): WPW is a rare type of SVT caused by an extra electrical pathway between the atria and ventricles, leading to rapid heart rates.
- Multifocal Atrial Tachycardia (MAT): MAT is a less common type of SVT characterized by rapid heart rates stemming from multiple locations in the atria, often seen in patients with underlying lung or heart conditions.
Risk Factors
Paroxysmal Supraventricular Tachycardia (PSVT) is a heart condition that can be triggered by various risk factors. These factors can include certain medical conditions, lifestyle choices, and genetic predispositions. Identifying and managing these risk factors can help in preventing episodes of PSVT.
- High blood pressure
- Heart disease
- Thyroid disorders
- Excessive alcohol consumption
- Stimulant use
- Stress
- Smoking

Book an AppointmentDiagnosis of Paroxysmal Supraventricular Tachycardia
Paroxysmal Supraventricular Tachycardia (PSVT) is typically diagnosed through various tests and examinations. Healthcare providers may consider the patient's medical history, symptoms, and conduct a physical exam to assess the heart rate and rhythm. Diagnostic tools such as electrocardiogram (ECG) or Holter monitor can help detect abnormal heart rhythms.
- Electrocardiogram (ECG)
- Holter monitor
- Event monitor
- Electrophysiology study
- Blood tests
- Echocardiogram
Treatment for Paroxysmal Supraventricular Tachycardia
Paroxysmal Supraventricular Tachycardia (PSVT) is a heart rhythm disorder that causes rapid heartbeats. Treatment options for PSVT include lifestyle changes, medications, and medical procedures. Lifestyle changes may involve avoiding triggers like caffeine and stress.
Medications can help regulate heart rhythm. In some cases, medical procedures like catheter ablation may be recommended to treat PSVT effectively. It's essential to consult with a healthcare provider for a proper diagnosis and personalized treatment plan for PSVT.
- Valsalva Maneuver: This technique involves holding your breath and straining, which can help restore normal heart rhythm by stimulating the vagus nerve.
- Adenosine: Administered intravenously in a medical setting, adenosine helps slow down the heart rate and interrupt abnormal electrical pathways in the heart.
- Cardioversion: This procedure involves delivering a controlled electric shock to the heart, resetting the heart's rhythm to normal sinus rhythm.
- Betablockers: Medications like metoprolol or atenolol can help control heart rate and reduce the frequency of episodes by blocking the effects of adrenaline on the heart.
- Catheter Ablation: In cases where other treatments are ineffective, catheter ablation is a minimally invasive procedure that destroys the abnormal heart tissue causing the tachycardia, restoring normal heart rhythm.
Frequently Asked Questions
