ABSTRACT
Objective To observe the success rate, complications of bedside pacing using ordinary electrodes lead guided by pacing signal in intensive care unit (ICU) and to summarize the procedure techniques.Methods 38 cases of temporary beside pacing conducted from June of 2004 to June of 2006 in our hospital from ICU were analysed retrospectively.Results 38 cases all achieved successful pacing within 15 minutes, non-sustainable ventricular tachycardia occurred in 2 patients; measuring electrodes were used successfully within 20 minutes to 2 cases with unstable pacing ;Electrodes lead micro-dislocation occurred 8 times in 6 cases. All patients recovered after prompt management. No serious complications such as thrombosis, embolism, pneumohemothorax or my ocardium perforation happened.Conclusion Bedside temporary cardiac pacing using ordinary electrodes lead guided by pacing signal is convenient, rapid, effective and safe. It is feasible in emergency cases and to prepare the measuring electrodes is necessary indeed in ICU.
ABSTRACT
Since the body is a good conductor,the pacing signals and cardio-signals can be acquired together by ECG measuring circuit. The high pacing signals interfere with the processing of cardio-signal. This paper introduces a new method for restraining pacing signals and compares it with the traditional one based on slew inhibition. The result indicates that the new method is superior to the traditional one.
