The path of blood through the heart begins with the right atrium receiving blood, which has circulated through most of the body. This blood is relatively low in oxygen because most of it has already been delivered to different organs and tissues.
Paroxysmal supraventricular tachycardia (PSVT) is another type of âshort-circuitâ arrhythmia. It may result either from atrio-ventricular nodal re-entrant tachycardia (AVNRT) or from an accessory pathway, which may occur as part of the Wolff-Parkinson-White (WPW) syndrome. PSVT may occur at any age and commonly occurs in patients who have no other types of heart disease.
