Abstract

A 12-lead ECG is used in emergency departments to diagnose and treat patients with chest discomfort. Performing ECGs at the proper time has been found to increase treatment outcomes. A timer on a wearable ECG ensures proper recording. We compared the timing accuracy of single-patch 12-lead ECG to conventional ECG, expecting the former to be more accurate. Adult patients with chest pain but not in shock were randomized into two groups: SP-ECG and C-ECG. The final analysis included 33 of the 36 recruited patients. The key result was the time taken to record the ECG in both groups. The two groups' average ages were 63.7 and 58.1 years. The SP-ECG group was 87.5 percent timely, while the C-ECG group was 47.0 percent (P.74). At the second follow-up, it was 75.0 percent and 35.2%. Continuous ECG without interfering with other exams is feasible in complex ER circumstances. But the accuracy of single-patch ECG has not been verified. The device also had some minor difficulties. The use of SP-ECG may help alleviate overcrowding or staffing issues in EDs, although more research is required.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 36 participants or records.
