PSVT, also called SVT, is a heart condition that causes unpredictable episodes of sudden, rapid rhythm

Is there a difference between PSVT and SVT?

Your healthcare provider may have said you have SVT, which is a general name for any fast regular heartbeat that starts in the upper part of the heart. SVT and PSVT are used interchangeably.

The “P” in PSVT stands for “paroxysmal,” which means starting and stopping suddenly. You can feel fine one moment, and the next, your heart is racing.

How do unpredictable PSVT episodes impact you?

When living with PSVT, do you often wonder:

  • When will my next episode start?

  • How long will it last?

  • How severe will it be?

  • What will I be doing when it happens?

Although PSVT episodes are not considered life-threatening, their impact can be significant.

What are some symptoms of a PSVT episode?

PSVT symptoms can vary from person to person or even across episodes, but rapid heartbeat, difficulty breathing, and dizziness are common.

Other symptoms may include:

  • Heart palpitations (pounding or fluttering feelings in the chest)

  • Chest pain

  • Shortness of breath

  • Fainting

  • Sweating

  • Weakness

PSVT episodes may stop on their own, but treatment may be needed to help the episodes and symptoms end faster.
