Paroxysmal supraventricular tachycardia (PSVT) is a type of arrhythmia that can cause rapid heartbeat, dizziness, and shortness of breath. If you cannot pronounce PSVT or find it too technical to use, there are several synonyms that you could use instead. These include Supraventricular Tachycardia (SVT), rapid heartbeat, fast heartbeat, irregular heartbeat, and heart palpitations. All of these synonyms refer to the same medical condition that is characterized by an abnormally fast heartbeat that originates in the upper chambers of the heart. Using these synonyms can help you communicate more effectively with healthcare professionals, patients, and other individuals who may be unfamiliar with PSVT.
