目的对作者自行研制的PACE3000型多功能心脏临时生理起搏器,作临床应用研究。方法对12例严重过缓型心律失常患者在无X线的环境下,用PACE3000型仪作多种方式的床旁起搏。结果PACE3000型仪配备的液晶显示器可清晰显示腔内心电图和体表心电图,从而指引临时起搏导管到位,该仪的感知、起搏、心电监护等功能运行良好,12例患者(2例AAI、6例VVI、2例VAT、2例DVI)实施临时心脏起搏,均获成功。结论使用PACE3000型仪可在任何环境下实施临时单腔或者双腔临时心脏起搏,具有开发价值及推广前景。
Objective To study the clinical application of the PACE3000 multi-function cardiac temporary physiological pacemaker developed by the author. Methods PACE3000 instrument was used to make bedside pacing in a variety of ways in 12 patients with severe bradyarrhythmia without X-ray. Results The PACE3000 was equipped with a liquid crystal display that clearly shows the endocardial electrocardiogram and the body surface electrocardiogram to guide the temporary pacing catheter in place. The function of sensing, pacing, and ECG monitoring of the instrument worked well. Twelve patients (2 AAI , 6 cases of VVI, 2 cases of VAT, 2 cases of DVI) to implement temporary cardiac pacing, were successful. Conclusion The PACE3000 instrument can be used in any circumstance to implement temporary single-chamber or double-chamber temporary cardiac pacing, which has the potential of development and promotion.
