Abstract

Paroxysmal supraventricular tachycardia (PSVT) is a common cardiac arrhythmia that often causes significant symptoms affecting quality of life and may lead to cardiovascular complications if prolonged. Among the underlying mechanisms, atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) are the most frequent. A total of 123 patients diagnosed with supraventricular tachycardia and indicated for radiofrequency catheter ablation according to the 2019 European Society of Cardiology guidelines were enrolled at Hanoi Medical University Hospital from January 2025 to December 2025. A short-term longitudinal descriptive study design was conducted. The mean age of the study population was 50.67 ± 16.11 years, with female predominance and most patients having no concomitant cardiovascular diseases. AVNRT was more common in older patients, whereas AVRT predominated in younger individuals; atrial tachycardia showed a relatively uniform age distribution. Left-sided accessory pathways were more frequently observed, and the most common origin of atrial tachycardia was near the coronary sinus ostium. The procedural success rate was 97.6%. Complications were mainly minor, including vascular access hematoma and vagal reactions, with no major complications reported.
