Description

Purpose: The purpose of this study is to investigate whether the wireless 12ch ECG system can reduce the required number of operators and time compared with the traditional cabled wired 12ch ECG system during exercise stress echocardiography.<br>Subjects and Methods: Thirty-one consecutive subjects (24 males; mean age, 66 ±11 years) who were suspected of having angina pectoris and planned to undergo exercise stress echocardiography were enrolled in this study. The stress echocardiography using the wireless 12ch ECG system was performed by two operators. Meanwhile, the stress echocardiography using the cable wired 12ch ECG system was carried out by two strategies, i.e., one performed by three operators (Method A) and the other by two operators (Method B). The elapsed time from the end of exercise to acquiring echo images was compared among three methods.<br>Results: All of the stress echocardiographic studies using the wireless 12ch ECG system (n = 12, 10 males; mean age, 67 ± 8 years), cable wired 12ch ECG system by three operators (Method A) (n = 12, 9 males; mean age, 64 ± 14 years), and cable wired 12ch ECG system by two operators (Method B) (n = 7, 5 males; mean age, 68 ± 12 years) were performed without any compilations. The elapsed time for the with wireless 12ch ECG system was 19 ± 3 seconds and that for Method A was 18 ± 4 seconds (p = N.S.), which shows that the wireless 12ch ECG system is as useful as the standard cabled wired method even when performed by two operators. However, it took 31 ± 9 seconds for Method B, which is longer than the times for the other two methods.<br>Conclusion: The wireless 12ch ECG System might reduce the operator’s burden and make the exercise stress echocardiography easier, implying that it is a valuable tool during exercise stress echocardiography.
