Abstract
Objective : To evaluate the management of optimal atrioventricular delay(AVD) in patients received dual chamber pacemaker. Methods: A total of 44 patients with pacemakers due to high-degree or complete atrioventricular conduction block were divided into 2 groups. The sensed AVDs of patients in study group were programmed under the direction of ultrasound,while patients in the control group were programmed by experience. All patients were examined and compared by echocardiography at baseline and the end of follow-up. Results: (1)The AVDs were different in 2 groups, (138.7 ± 8.7) ms in the study group, while( 124.8 ± 0. 8)ms in the control group, P＜0. 001. (2)The results of echocardiography were similar in two groups at baseline. (3)In the end of follow-up, the diameters of left atria in study and control group were (36 ± 2. 8) and (38.7 ± 3.4)mm, respectively. P = 0.008; the diameters of left ventricle were (46. 7 ± 4. 5) and (49.4 ± 5.2) mm, respectively, P = 0. 07.The left atria and ventricle were enlargement in control group. The Ei in 2 groups were (13.2 ± 0.9) and (9.9 ± 1.7) ;Al were (5.1 ± 0.9) and (4.1 ± 0.9);left ventricular ejection fractions were (58.6 ± 2.2) ％ and (55.3 ± 4.1 ) ％ ; stroke volumes were (63 ± 5.2) and (54.9 ± 6. 6)mi, respectively, P＜0.05. The function of the heart in patients in control group was reduced comparably. Conclusions: The optimal AVD benefit the function of the heart in patients with dual chamber pacemakers, and echocardiography is a simple and valid tool for evaluating the optimal AVD.关键词
