This study is carried out to describe types of clinical characteristic of paroxysmal supraventricular tachycardia attack (PSVT) between young and elderly patients who underwent cardiac electrophysiology test. This is a cross sectional descriptiveand prospective study. 182 patients who were diagnosed with PSVT attack underwent cardiac electrophysiological test at Vietnam Heart Institute during 01/2014-05/2017. The patients were divided into two groups: Group I (n=93) is the young patients (< 60 years of age) and Group II (n=89) is a elderly patients (≥ 60 years of age).: Group I (young patients) accounted for 51.1% and Group II (elderly patients) made up 48.9%. vThe rate of PVST attack in female was 70.0% while that in male was 29.1% (P>0.05); the mean age of elderly patients was higher than younger patients (p < 0.0001). The PVST attacks have moredate positive correlation with structure (R = 0.355) and hypertension (R = 0.314), there are differences between both groups in the structure and hypertension. The structure and hypertension rates of patients in elderly petients group were higher than those in young patients group (p < 0.0001), there is a strongly postive correlation between the structure and hypertension patients (R = 0.966, p < 0.0001). Characteristics of PVST attack are 68.3% of atrioventricular nodal reentrant (AVNRT) and 29.6% of atrioventricular reciprocating tachycardia (AVRT) attacks; The AVNRT and AVRT attack rates in female were 74.8% and 61.8% respectively, whereas the AVNRT and AVRT attack rates in male were 25.2% and 28.2% respectively (p > 0.05). PVST attacks were more common in female patients than in male patients. the likelihood of having AVNRT was higher compared to AVRT attacks, and the mean age of AVNRT and AVRT attack in the elderly patients was higher than that in young patients.
