Abstract:
Objective To observe the rate-adaptive response of dual sensor pacemakers integrated with activity sensor and minute ventilation sensor.Methods Fifty patients with chronotrepic incompetence were implanted with pacemakers of integrated sensor.The patients with pacemakers implanted were arranged to take upstairs test,downstairs test and tapping test under the monitor of integrated sensor,minute ventilation sensor and activity sensor respectirely.The rate-adaptive responses were tracked down every 15 seconds with remote heart rate monitor.The results were compared with the control group patients with normal sinal chronotropic function(n=15).Results In activity sensor group,pacing rates were significantly higher than the normal control group in downstairs test and tapping test.In minute ventilation sensor group,pacing rates increasement was significantly slower in the beginning of upstairs test.Pacing rates of integrated group were similar to the normal control group in upstairs and downstairs tests.Conclusion The rate-adaptive pacing response of dual sensor integrated with activity sensor and minute ventilation sensor,which is mostly close to the normal chronotropic response,better than that of single sensor.
