Normally, the chambers of the heart (atria and ventricles) contract in a coordinated manner.
The contractions are caused by an electrical signal that begins in an area of the heart called the sinoatrial node (also called the sinus node or SA node). The signal moves through the upper heart chambers (the atria) and tells the atria to contract. After this, the signal moves down in the heart and tells the lower chambers (the ventricles) to contract.
The rapid heart rate from PSVT may start with events that take place in many different areas above the lower heart chambers (ventricles).
PSVT can occur with digitalis toxicity and with conditions such as Wolff-Parkinson-White syndrome.
The condition occurs most often in young people and infants.
The following increase your risk for PSVT:
Alcohol use Caffeine use Illicit drug use Smoking
What causes supraventricular tachycardia?
Normally, the chambers of the heart (atria and {{NAME}}) contract in a coordinated manner.
The contractions are caused by an electrical signal that begins in an area of the heart called the sinoatrial node (also called the sinus node or {{ORGANIZATION}} node). The signal moves through the upper heart chambers (the atria) and tells the atria to contract. After this, the signal moves down in the heart and tells the lower chambers (the {{NAME}}) to contract.
The rapid heart rate from PSVT may start with events that take place in many different areas above the lower heart chambers ({{NAME}}).
