  Download in pdf format   Extended summary: The aim of this paper is to assess the influence of RVOT (Right Ventricle Outflow Tract) and RVA (Right Ventricle Apex) position of ventricle pacemaker lead on LVEF and volume, after 12 months of pacemaker stimulation in patients with preserved LVEF. The LVEF was measured with two independent methods, RNV (radionuclide venticulography) and echocardiography. Patients and methodology: this was prospective, randomized follow up study that lasted for 12 months. Our research enveloped 132 consecutive patients implanted with permanent antibradicardiac pacemaker in Zaječar Pacemaker Centre during the period of 2009 to 2011. Regarding the electrode position, all patients were divided into two groups: RVA group with 61 patients with ventricle lead implanted in the right ventricle apex and RVOT group with 71 patients with ventricle lead implanted in right ventricle outflow tract. Results: On study enrollment, there was no group difference in the distribution of gender, age, BMI, VVI to DDD implantation ratio, LVEF, ESV, EDV measured with RNV, and to ESD, EDD, ESV, ESVI measured with echocardiography. After 12 months of pacemaker stimulation, the groups showed no difference in systolic parameters measured with RNV and echo. The only observation was that the ESVI and ESVI measured with echo were slightly elevated on the border of statistical significance only in the RVOT group. Conclusion: Pacemaker stimulation from RVOT or RVA in patients with preserved left ventricle systolic function did not have a negative effect on ejection fraction or left ventricle volumes after 12 months of pacemaker stimulation, measured by two independent noninvasive diagnostic methods.
Key words: RVA, RVOT, pacemaker stimulation, left ventricle systolic function
