Objective To observe the effect of physiological pacing on bradycardiac,cardiac function and improvement of quality of life.Method Retrospetive study was made to analyse 310 pacemakers including VVI 78 cases,DDD 164 cases,VVIR 16 cases,DDDR 52 cases from August 1999 to Spring 2005.The mean following time was(36±1.8) months.During the period,we explored the symptom,living quality,excise capability,cardiac function.Results Except for the patients having atrial fibrillation with bradycardia or long duration,82.4 percentage of the patients had implanted dual chambers pacemaker.After implanted the physiological pacemakers,the cerebral ischemic symptoms of the patients including amaurosis,syncope,swirl and so on disappeared,cardiac dysfunction and the exercise capacity improved.No pacing syndrome and no pacemaker intervened tachycardia was observed.Compared with the patients of implanted the physiological pacemakers,84.2 percentage of the patients resolved no cerebral ischemic symptoms,and the occurrence of cardiac dysfunction was higher than the formers.Conclusion Physiological pacing could improve cardiac function and living quality and decrease the occurrence of para atrial fibrillation and pacing syndrome,which is superior to unphysiological pacing.We should advocate physiological pacing. |
