Pacemakers with a rate-responsive function, based on calculation of ventilatory minute volume, may induce tachycardia in patients who undergo hyperventilation during general anaesthesia. If hyperventilation is desired, it is recommended that the pacemaker is reprogrammed in order to avoid tachycardia. If the programming device is not available, a magnet may be placed over the pacemaker site to convert it to fixed-rate pacing.
基于每分钟通气量计算的具有频率应答功能的起搏器，可能会在全身麻醉期间过度通气的患者中诱发心动过速。如果需要进行过度通气，建议对起搏器重新编程以避免心动过速。如果没有编程设备，可以在起搏器部位放置一块磁铁，将其转换为固定频率起搏。
