RESUMO
Objective To investigate the application of remote monitoring systems for cardiac implantable electronic devices (CIED) and its success rate of data transmission in elderly patients.Methods A total of 97 elderly patients who had previously undergone procedures for pacemaker implantation,implantable cardioverter defibrillators (ICD) or cardiac resynchronization therapy (CRT) with remote monitoring capabilities between January 2013 and October 2016 at our hospital were enrolled.We evaluated the effect of the remote monitoring systems for data transmission,compared the outpatient follow-up rates between the groups one year after implantation,and conducted a telephone survey of patients.Results A total of 97 elderly patients,including 70 with pacemakers,20 with ICD and 7 with CRT,were enrolled in this study.Participants had a mean age of (78.2-±-6.4) years and 64 were male (66.0％).The Home Monitoring system was used for 85 cases and the Merlin.net remote monitoring system was used for 12 cases.Overall,95 patients (97.9 ％) completed the remote monitoring procedure,68 patients (70.1％) completed the outpatient follow-up,and 90 patients (92.8％) completed the telephone survey during a one-year follow-up period.The satisfaction rate for the remote monitoring systems was 94.4％ (85 patients),and 80 patients (90.0％％) expressed a willingness to continue to use the remote monitoring system if a replacement was needed.Conclusions For elderly patients with CIED,the remote monitoring systems can improve the follow-up rate with a high degree of satisfaction.
RESUMO
Objective To observe the effect of Guanxin Ⅱ Hao on plasma NO and NOS in dog with myocardial ischemia. Methods 20 dogs of myocardial ischemia were divided into the control group, isosorbidi mononitratis group and the Guanxin Ⅱ Hao group by random. The NO and NOS of serum were measured, before and after treatment. Results In the control group, the level of NO and NOS were higher than that of the isosorbide mononitrate group. There was significant difference between the control group and the Guanxin II Hao groups (P
RESUMO
Objective To investigate the way of pacemaker implantation in 127 elderly patients over 80 years old to reduce postoperative complications and improve the life quality. Methods One hundred and twenty-seven patients over 80 years old had the dual chamber pacing in 95 cases(74. 8%, including tri-chamber pacing) and the single ventricular pacing in 32 cases (25. 2%). Cephalic veins were used primarily in all patients with modified methods. The safe fixation of pacing leads were emphasized not only in the heart but also in the site of pacemaker pocket. The pacemaker package was made prior to the leads insertion in order to have enough time for stopping bleeding. It was necessary for some cases with diffused bleeding to use electric coagulation. All patients were told to get out of bed in the operating day or the day after procedure. Results Cephalic vein was well exposed. The successful rates of implanting pacing leads directly through cephalic vein were 92. 0% and 81. 5% in the single chamber and dual chamber patients, respectively. The overall complications observed in 5 cases(3. 9%) were pocket hematoma formation in 3 cases (2. 4%), cardiac tamponade in 1 case (0.8%), and disconnection of pacemaker with lead in 1 case (0.8%). There were no hemothorax, infection and lead dislodgement. Conclusions Insertion of pacing lead through cephalic vein is important, especially for the advanced aged patients. This operation can decrease the complications of subclavian vein puncture. Leads dislodgement are mainly due to the inadequate skill of operator, not to the patient s early activity out of bed. Appropriate way for stopping bleeding is the key to protect the patients from pacemaker pocket effusion and hemotama.
