PSVT, abbreviated from Paroxysmal Supraventricular Tachycardia, refers to a type of rapid heart rate or tachycardia that originates above the ventricles of the heart. It is a condition characterized by sudden episodes of fast heartbeats, typically occurring sporadically and without any warning signs. PSVT specifically involves the abnormal generation or conduction of electrical impulses within the heart's upper chambers or atria, leading to a rapid heart rate.
During PSVT episodes, the heart may beat at a rate of over 100 to 250 beats per minute, causing palpitations, chest discomfort, dizziness, shortness of breath, and sometimes fainting. These symptoms typically subside on their own within a few minutes or hours, but the condition can recur intermittently.
Various factors can trigger PSVT, including excessive caffeine consumption, stress, certain medications, alcohol, smoking, and underlying heart conditions. Treatment for PSVT often involves managing potential triggers and may include vagal maneuvers (stimulating the vagus nerve to slow down the heart rate), medications, or more invasive measures such as catheter ablation.
It's important for individuals experiencing PSVT symptoms to seek medical attention to obtain a proper diagnosis and potential treatment. While causing discomfort and moments of concern, PSVT is typically not life-threatening but can significantly impact a person's quality of life if left unmanaged.
