Common paroxysmal supraventricular tachycardia symptoms

Paroxysmal supraventricular tachycardia is a heart rhythm problem that appears suddenly, causing rapid heartbeat. Discover causes, signs, and treatments.

What are the main causes of paroxysmal supraventricular tachycardia (PSVT)?

• Abnormal electrical pathways in the heart can trigger rapid heartbeats, often caused by reentry circuits disrupting normal rhythm control.
• Stress, caffeine, alcohol, or stimulant medications may increase susceptibility, making sudden PSVT episodes more likely in sensitive individuals.
• Underlying conditions such as congenital heart defects, thyroid disorders, or hypertension can predispose people to recurrent PSVT episodes over time.

Key symptoms of paroxysmal supraventricular tachycardia (PSVT) to watch for

• A sudden rapid heartbeat often exceeding 150 beats per minute, which may start and stop unexpectedly without warning signs.
• Dizziness, lightheadedness, or fainting can occur due to reduced blood flow during prolonged PSVT episodes.
• Chest discomfort, shortness of breath, or fatigue may appear, especially in individuals with pre-existing cardiovascular conditions.

How can you prevent paroxysmal supraventricular tachycardia (PSVT) effectively?

• Limit caffeine, alcohol, and stimulant intake to reduce potential triggers that may provoke sudden PSVT episodes.
• Manage stress through relaxation techniques, regular exercise, or mindfulness practices to stabilize heart rhythm.
• Follow medical advice, including prescribed medications or procedures like catheter ablation, to control and prevent recurrent PSVT episodes.
