METHODS: We prospectively enrolled 20 patients(age 59.45 ± 18.1 years; male: 65%) with CHB, who were implanted with a dual chamber pacemaker. The left ventricular outflow tract velocity time-integral was measured after AV/PV delay optimization by both echocardiography and Quick Opt algorithm method. Bland-Altman analysis was used for agreement between the two techniques. RESULTS: The optimal AV and PV delay determined by echocardiography was 155.5 ± 14.68 ms and 122.5 ± 17.73 ms(P < 0.0001), respectively and by Quick Opt method was 167.5 ± 16.73 and 117.5 ms ± 9.10 ms(P < 0.0001), respectively. A good agreement was observed between optimal AV and PV delay as measured by two methods. However, the correlation of the optimal AV(r = 0.0689, P = 0.77) and PV(r = 0.2689, P = 0.25) intervals measured by the two techniques was poor. The time required for AV/PV optimization was 45.26 ± 1.73 min by echocardiography and 0.44 ± 0.08 min by Quick Opt method(P < 0.0001).CONCLUSION: The programmer based IEGM method is an automated, quick, easier and reliable alternative to echocardiography for the optimization of AV/PV delay in CHB patients, implanted with a dual chamber pacemaker.展开更多
