医院外的心脏病人可以采用Holter监护仪进行12或24小时的心电图磁带记录,然后进行心电波的分析。但是Holter监护仪有其局限性。因为心律失常不一定在记录期间发生,实际上许多病人的心律失常在数天或数周内才发生一次,使磁带记录往往有漏记或难以记录到的情况。即使恰被记录在磁带上,但在检出时,由于待检测的磁带数量大,容易发生错检。即使应用了Holter磁带自动分析计算机系统,但记录与分析工作耗时较长,
Cardiac patients outside the hospital can use the Holter monitor to record 12 or 24 hours of ECG tape and then analyze the ECG. But Holter monitors have their limitations. Because arrhythmias do not necessarily occur during recording, in fact many arrhythmias occur only once a matter of days or weeks, making tape recording often missed or difficult to document. Even if it is recorded on the tape just as it is, it is prone to misjudgment due to the large number of tapes to be detected upon detection. Even though Holter tape automated analysis computer systems were used, recording and analysis took a long time,
