Objective To analyze the clinical application and electrocardiogram（ECG） collection of critical values in remote routine electrocardiogram consultation

so as to better serve basic hospitals and patients. Methods From May 1

2019 to April 30

2021

a total of 51

282 ECG remotely consulted by ECG cloud network in Henan Provincial People’s Hospital were retrospectively analyzed. ECG consultation volume

types of critical ECG values and unqualified ECG collection in the two years were compared and analyzed. To observe the clinical application of critical value of remote ECG consultation and further standardize the next ECG collection. Results From May 1

2019to April 30

2020（The first year）

30012 ECG were remotely consulted through ECG cloud network. From May 1

2020 to April 30

2021（year 2）

a total of 21270 ECG were consulted. In the first year

597 cases of critical value were consulted

accounting for 1.99% of the annual consultation volume. In the second year of consultation

there were1687 cases with critical value

accounting for 7.93% of the annual consultation volume. The difference of critical value in ECG consultation in the first year and the second year was statistically significant（p<0.05）. In the distribution of critical value in the first year and the second year

"suspected acute myocardial infarction" accounted for the highest proportion. The ECG of 10 small categories with a relatively large number of critical values was selected for analysis. It was found that the incidence of suspected myocardial infarction

suspected acute myocardial ischemia

ventricular flutter

ventricular fibrillation and ventricular tachycardia during ECG consultation in the second year was higher than that in the first year

and the difference was statistically significant（p<0.05）. In the first year of consultation

1730cases of ECG collection were unqualified

accounting for 5.76% of the annual consultation. In the second years’ consultation cases there were a total of 1065 cases of ECG acquisition is unqualified

accounting for 5.01% than the annual amount of consultation

the first year and the second years’ electrocardiogram consultation

ECG fraction defective differences were statistically significant（p<0.05）. In the second years

the lead reverse connection

large interference

baseline drift

lead not connected or the loss rate was lower than the first year. The incidence of false error and equipment failure was higher than that in the first year

and the difference was statistically significant（p<0.05）.Conclusions Setting the critical value of remote routine ECG consultation can make the basic hospital find the critical state of patients in time

make the critical patients get treatment faster

and facilitate the later diagnosis and treatment of patients. At the same time

we should further strictly control the quality of ECG collection in order to better serve patients at the grass-roots level.
