A study published in the JACC clinical electrophysiology has shown that Right Heart Strain (RHS) on ECG done at admission was associated with mechanical ventilation and mortality in patients admitted with COVID-19. Therefore, special attention should be taken in patients admitted with new signs of RHS on presenting ECG.

The study retrospectively evaluated records from 480 patients who were consecutively admitted with COVID-19. ECGs obtained at presentation in the emergency department (ED) were considered index ECGs. RHS-ECG was defined by any new right-axis deviation, S1Q3T3 pattern, or ST depressions with T-wave inversions in leads V1 to V3 or leads II, III, and aVF.

Multivariable logistic regression was performed to assess whether RHS-ECGs were independently associated with primary outcomes.

- ECGs from the ED were available for 314 patients who were included in the analysis.
- Most patients were in sinus rhythm, with sinus tachycardia being the most frequent dysrhythmia.
- RHS-ECG findings were present in 40 patients.
- RHS-ECGs were significantly associated with the incidence of adverse outcomes and an independent predictor of mortality , the need for mechanical ventilation , and their composite.

The team concluded that, RHS-ECG was associated with mechanical ventilation and mortality in patients admitted with COVID-19. Special attention should be taken in patients admitted with new signs of RHS on presenting ECG.
