| الوصف: | Introduction: In a variety of cardiovascular diseases, low QRS voltage amplitude on the 12-lead ECG is associated with poor prognosis. We studied the relative frequency and importance of this phenomenon in hospitalized patients with SARS-coronavirus 2019 (CoViD-19) - a condition associated with myocardial injury in ~1/3 of patients. Methods: We performed a retrospective analysis of 800 consecutive patients with laboratory-confirmed CoViD-19 hospitalized from Mar 7 and Apr 12, 2020. Patients without a final disposition or telemetry data were excluded, resulting in 140 patients. On 12-lead ECG, low amplitude was defined as QRS amplitude Results: Among 140 patients, 33 (23.6%) met criteria for low QRS amplitude. Compared to patients without low amplitude, these patients had a higher risk of in-hospital mortality (72.7% vs 26.2%; p Conclusions: A reduction in electrocardiographic QRS amplitude in patients with CoViD-19 is the strongest clinical predictor of death, and may be useful for risk stratification during hospitalization. Further study is needed to elucidate the mechanisms underlying changes in QRS amplitude, and their relationship to disease severity. |
