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.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Electrocardiogram01:29

Electrocardiogram

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Correlation between ECG and Cardiac Cycle01:25

Correlation between ECG and Cardiac Cycle

The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the 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...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
