Paroxysmal Supraventricular Tachycardia

Paroxysmal supraventricular tachycardia (PSVT) is a type of arrhythmia in which the heart beats rapidly and suddenly, originating above the ventricles. Episodes typically start and end abruptly.

Frequent symptoms: rapid palpitations, a sensation of strong heartbeats in the chest, dizziness, shortness of breath and, at times, discomfort or anxiety during the episode.

When to see a doctor? A checkup is important if the episodes are frequent, last a long time, or are accompanied by fainting, chest pain, or difficulty breathing.

Which specialist treats it? The cardiologist is the professional who studies and follows up on this arrhythmia, with support from the pediatric cardiologist when it appears in childhood. If you notice episodes of sudden rapid heartbeats, it is worth having a cardiologist evaluate them to clarify their origin.
