An 84-year-old female patient presented to the coronary care unit with dizziness. A DDD-R minute ventilation sensor pacemaker had been implanted eight years previously. The ECG showed an atrial and ventricular paced rhythm of 140 beats/min. After disconnecting the patient from the cardiac monitor the pacemaker rate dropped gradually to 90 beats/min. The cardiac rhythm monitoring system applies low-amplitude electrical pulses in order to measure respiration rate by transthoracic impedance (TTI) measurement. The minute ventilation pacemaker sensor is driven by the same TTI measurement for rate response. Inappropriate interference between these two systems caused a sensor-driven high pacemaker rate. The dizziness was not related to the sensor-driven high rate.
一名84岁女性患者因头晕入住冠心病监护病房。八年前植入了一台DDD-R分钟通气传感器起搏器。心电图显示心房和心室起搏心律，心率为140次/分钟。将患者与心脏监护仪断开连接后，起搏器频率逐渐降至90次/分钟。心脏节律监测系统施加低幅度电脉冲，以便通过经胸阻抗（TTI）测量来测量呼吸频率。分钟通气起搏器传感器由相同的TTI测量驱动以进行频率响应。这两个系统之间的不适当干扰导致了传感器驱动的高起搏器频率。头晕与传感器驱动的高频率无关。
