Insights
Right ventricular strain, identified by ECG, is a significant predictor of mortality in COVID-19 patients. This finding highlights the importance of ECG in assessing COVID-19 prognosis and patient outcomes.
Area of Science:
- Cardiology
- Infectious Diseases
- Critical Care Medicine
Background:
- The ongoing COVID-19 pandemic continues to cause significant morbidity and mortality worldwide.
- Assessing prognostic factors in hospitalized COVID-19 patients is crucial for timely intervention and improved outcomes.
Purpose of the Study:
- To investigate the prognostic value of right ventricular (RV) strain, as detected by electrocardiogram (ECG), in predicting mortality among patients hospitalized with COVID-19.
Main Methods:
- A cohort of 324 adult COVID-19 patients admitted between April 1-30 was analyzed.
- Right ventricular strain was defined by specific ECG findings (RBBB, T-wave changes, S1Q3T3).
- Multivariable Cox regression analysis was used to identify independent predictors of in-hospital mortality.
Main Results:
- Twenty-nine percent of patients exhibited RV strain on ECG.
- In-hospital mortality was observed in 20% of the study cohort.
- RV strain on ECG, along with high-sensitivity troponin I, d-dimer, and age, independently predicted mortality (OR: 4.385, p < 0.001).
Conclusions:
- The presence of a right ventricular strain pattern on ECG is significantly associated with in-hospital mortality in COVID-19 patients.
- ECG-based RV strain assessment can serve as a valuable prognostic tool in the management of COVID-19.
- Early identification of RV strain may aid clinicians in stratifying risk and optimizing care for critically ill COVID-19 patients.
Objective:
COVID-19 spread worldwide, causing severe morbidity and mortality and this process still continues. The aim of this study to investigate the prognostic value of right ventricular (RV) strain in patients with COVID-19.
Methods:
Consecutive adult patients admitted to the emergency room for COVID-19 between 1 and 30 April were included in this study. ECG was performed on hospital admission and was evaluated as blind. RV strain was defined as in the presence of one or more of the following ECG findings: complete or incomplete right ventricular branch block (RBBB), negative T wave in V1-V4 and presence of S1Q3T3. The main outcome measure was death during hospitalization. The relationship of variables to the main outcome was evaluated by multivariable Cox regression analysis.
Results:
A total of 324 patients with COVID-19 were included in the study; majority of patients were male (187, 58%) and mean age was 64.2 ± 14.1. Ninety-five patients (29%) had right ventricular strain according to ECG and 66 patients (20%) had died. After a multivariable survival analysis, presence of RV strain on ECG (OR: 4.385, 95%CI: 2.226-8.638, p < 0.001), high-sensitivity troponin I (hs-TnI), d-dimer and age were independent predictors of mortality.
Conclusion:
Presence of right ventricular strain pattern on ECG is associated with in hospital mortality in patients with COVID-19.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
