Understanding Paroxysmal Superventricular Tachycardia (PSVT)

PSVT, a sudden onset tachycardia, presents varied symptoms in patients, ranging from palpitations in the chest, rapid pulse, to sensations of breathlessness and lightheadedness. Episodes can last from seconds to minutes or even extend to a day, impacting patients' daily activities. Contrary to sinus tachycardia driven by external factors, PSVT originates from abnormal heart rhythms, often involving the atria or AV nodal tissues.
