Abstract

Objective To explore the significance of carotid ultrasonography in patients with paroxysmal supraventricular tachycardia and hypertension.Methods 120 cases of paroxysmal supraventricular tachycardia and hypertension underwent high-frequency color Doppler ultrasound to measure carotid artery diameter and intima-media thickness (IMT).Selected 113 cases of simple hypertension as the control group.Results Incidences of carotid artery plaque and thickening IMT of patients with paroxysmal supraventricular tachycardia and hypertension were 82.5% and 75.4% respectively,significantly higher than 30.7% and 41.3%of the control group (P < 0.05).Left and right IMT of patients with paroxysmal supraventricular tachycardia and hypertension were (0.96 ± 0.13) mm and (0.98 ± 0.10) mm,significantly different from (0.68 ± 0.07) mm and (0.70 ± 0.08) mm of the control group (P < 0.01).Left and right carotid artery diameter of patients with paroxysmal supraventricular tachycardia and hypertension were (0.77 ± 0.12) mm and (0.73 ± 0.10) mm,those of the control group were (0.68 ± 0.06) mm and (0.69 ± 0.07) mm,without statistically significant difference (P > 0.05).Conclusion The incidence of carotid atherosclerosis in patients with paroxysmal supraventricular tachycardia and hypertension increased. Key words: Carotid ultrasonic examination; Paroxysmal supraventricular tachycardia; Hypertension
