Abstract
Objective: Describe of type of characteristics of supraventricular tachycardia (SVT) attack between young and elderly patients and other arrhythmias on the patients were cardiac electrophysiology study. Subject and method: Cross sectional descriptive study, and prospective study. 186 patients were diagnosed with the SVT attack were cardiac electrophysiology study at Vietnam Heart Institute during January 2014 to May 2017. The patients were divided into two groups: Group I (n = 95) is the young group (< 60 years of age) and group II (n = 91) is a elderly group (≥ 60 years of age). Result: Group I (young group) had 51.1% and group II (elderly group) had 48.9%. Characteristics of the SVT attack have 68.3% AVNRT, 29.6% AVRT and 2.2% AT were met in Wolff-Parkinson-White (WPW) syndrome patients. The female had 69.4% of SVT attack were more than male patients had 30.6%; the female had atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) were 74.8% and 61.8%, respectively, only 9.8% of the patients had WPW syndrome by Electrocardiogram (ECG), atrial fibrillation-flutter (AF-Flutt) met in 15.6% and branch block met in 5.9%, the eldely patients have atrial fibrillation-flutter (24.2%) more than young patients group (7.4%), p<0.05. Conclusion: The supraventricular tachycardia attack were more common in female more than male patients, the likehood of having AVNRT was higher than the AVRT attacks, the mean age of AVNRT and AVRT attack were the elderly patients more than the young patients, the rate of atrial fibrilation-flutter was relatively common in the SVT attacks and in elderly patients group, WPW syndrome was associated with the SVT attacks in clinical, and ECG of out of attacks in the elderly group having AVRT attack was higher than the young patients group.
