Background/PurposeIn-hospital cardiac arrest is a serious issue for hospitalized patients. The documented initial rhythm and detected medical events have been reported to influence the survival of cardiopulmonary resuscitation. This study aimed to identify the effect of continuous real-time electrocardiogram (ECG) monitoring on the prognosis of resuscitated patients in a general cardiac ward.MethodsWe conducted this retrospective study using medical records of hospitalized patients in a cardiovascular ward who experienced an in-hospital cardiac arrest and received cardiopulmonary resuscitation from February 2015 to December 2018. The patients who were considered to be at high risk of cardiac events such as ventricular arrhythmia would receive continuous ECG monitoring. A wireless ECG telemonitoring system was introduced to replace traditional bedside ECG monitors. The outcome measures were the initial success of resuscitation, 24-h survival after resuscitation, and survival to discharge.ResultsWe enrolled 115 patients with a cardiac arrest during hospitalization, of whom 73 (63%) patients received wireless ECG telemonitoring. Patients receiving continuous ECG monitoring were associated with higher opportunities of initial success of resuscitation and 24-h survival after resuscitation (67.1% vs. 40.5%, p = 0.005; and 49.3% vs. 26.2%, p = 0.015, respectively) when comparing to the non-monitoring group; but no significant difference in survival to discharge (21.9% vs. 16.7%, p = 0.498) was observed. With adjustment of the covariates, the monitoring group was associated with a higher likelihood to reach the initial success of resuscitation (odds ratios [ORs], 3.21; 95% confidence interval [CI], 1.03-9.98). However, the effect of monitoring on 24-h survival and survival to discharge was close to null after adjusting for covariates.ConclusionA wireless ECG telemonitoring system were beneficial to the initial success of resuscitation for patients at high risk of cardiovascular events suffering an in-hospital cardiac arrest; but had less impact on 24-h survival and survival to discharge.Copyright © 2020 Formosan Medical Association.
