Objective: Describe of rhythm characteristics of types of paroxysmal supraventricular tachycardia (PSVT) attack in young and elderly patients undergoing cardiac electrophysiology. Subject and method: Cross-sectional descriptive and prospective study. 182 patients diagnosed with PSVT attack underwent cardiac electrophysiology in Vietnam Heart Institute from January 2014 to May 2017. The patients were divided into two groups: Group I (n = 93): Young patients (< 60 years old), group II (n = 89): Elderly patients (≥ 60 years old). Result: The PSVT attack was quite common in middle-aged. AVNRT type was more commonly seen than AVRT attack, typical AVNRT were more prevalent than atypical AVNRT, orthodromic AVRT was more common than antidromic AVRT. The proportion of combined AVRT attack and WPW syndrome in the elderly group were significantly higher than that in the young group (p<0.0001). The heart rate on out of attack ECG in the young patient group was significantly higher than that in the elderly patient group (p<0.0001, r = -0.326). The AFib was quite common in PSVT attacks, with the rate of elderly patients having AFib attacks was higher than that of young patients (p<0.05); The AFib was common in AVRT attacks (60%) while it was not common in AVNRT attacks (4.7%). The branch block was seen in 6.0%. Conclusion: The likelihood of having AVNRT was higher compared to AVRT attacks, typical AVNRT were more prevalent than atypical AVNRT, orthodromic AVRT was more common than antidromic AVRT, WPW syndrome was associated with PSVT attacks, there was a moderately and negatively correlated between the heart rate and age. The AFib was quite common in PSVT attacks, with the rate of elderly patients having AFib attacks was higher than that of young patients. The AFib was common in AVRT attacks.
