OBJECTIVE
To assess the value of a cardiac technicians' report on electrocardiographs (ECGs) in reducing serious errors of interpretation by senior house officers.
METHODS
A parallel study of interpretation of ECGs by senior house officers from 238 cases seen in an accident and emergency (A&E) department in a teaching hospital. 129 ECGs were reported by a cardiac technician at the time of recording and before the senior house officer wrote a report, and 109 were reported only by the senior house officers. Misinterpretations by doctors and technicians were graded by a consultant cardiologist on a four point scale and compared in the two groups. Serious errors (grade 4) were defined as those which potentially affected immediate management.
RESULTS
The number of grade 4 errors of interpretation of ECGs by A&E senior house officers was reduced by 59% when there was a prior technical report (mean (SD), 18(17)% v 6 (7%); Fisher's exact test P < 0.05).
CONCLUSIONS
When cardiac technicians provide a report on an ECG at the time of its recording, serious errors of interpretation by senior house officers are reduced.
目的
评估心脏科技术人员的心电图（ECG）报告对于减少住院医师严重解读错误的价值。
方法
对一家教学医院急诊科238例病例的心电图解读进行平行研究。129份心电图在记录时且在住院医师撰写报告之前由心脏科技术人员报告，109份仅由住院医师报告。医生和技术人员的错误解读由一位心内科顾问医师按四级量表分级，并在两组之间进行比较。严重错误（4级）定义为那些可能影响即时处理的错误。
结果
当有一份技术人员预先报告时，急诊科住院医师对心电图的4级解读错误数量减少了59%（均值（标准差），18(17)%对6(7)%；Fisher精确检验P<0.05）。
结论
当心脏科技术人员在心电图记录时提供报告时，住院医师的严重解读错误会减少。
