Insights
COVID-19 patients with sepsis indicators faced higher arrhythmia risks and poorer outcomes. Elevated inflammatory markers correlated with increased arrhythmias and mortality in these patients.
Area of Science:
- Cardiology
- Infectious Diseases
- Internal Medicine
Background:
- Cardiac arrhythmias can arise during SARS-CoV-2 infection due to direct viral impact, systemic inflammation, or pharmacotherapy side effects.
- Mechanisms include viral effects on cardiovascular systems, proarrhythmic drug actions, drug interactions, and autonomic dysfunction.
- Accurate arrhythmia risk assessment is crucial for managing severe infections and developing effective interventions.
Purpose of the Study:
- To investigate the incidence and risk factors of cardiac arrhythmias in hospitalized COVID-19 patients.
- To correlate laboratory markers of inflammation and sepsis with arrhythmia development and patient outcomes.
- To inform clinical management strategies for COVID-19 patients at risk of arrhythmias.
Main Methods:
- Retrospective observational study of 151 COVID-19 patients.
- Data collected from hospitalized patients at the Timisoara County Emergency Hospital (2020-2022).
- Analysis of arrhythmia occurrence, inflammatory markers, and sepsis indicators.
Main Results:
- Atrial fibrillation was the most frequently observed arrhythmia.
- Elevated inflammatory markers were linked to a higher risk of arrhythmias.
- Higher risk of arrhythmias and increased mortality were associated with elevated inflammatory markers.
Conclusions:
- Sepsis onset, indicated by laboratory markers, correlated with increased arrhythmia incidence.
- Sepsis was associated with an unfavorable disease outcome in COVID-19 patients.
- Findings highlight the link between inflammation, sepsis, and cardiac arrhythmias in COVID-19.
Abstract:
Background and Objectives: Cardiac arrhythmias during the SARS-CoV-2 infection may occur due to the direct impact of the virus on the respiratory and cardiovascular systems, as well as through the broader effects of systemic inflammation, or a combination of both. Additional mechanisms include the proarrhythmic effects of COVID-19 pharmacotherapies, drug-drug interactions, and associated autonomic dysfunction. To improve future risk stratification and clinical management, it is essential to accurately assess the risk of arrhythmia in the context of severe infections, in order to develop diagnostic and therapeutic algorithms that support the fastest and safest possible interventions. Materials and Methods: This retrospective observational study included 151 patients diagnosed with COVID-19, who were hospitalized at the Cardiology Clinic of the Timisoara County Emergency Hospital between 2020 and 2022. Results: The most common arrhythmia observed was atrial fibrillation. Elevated inflammatory markers were associated with a higher risk of arrhythmias and increased mortality. Conclusions: The onset of sepsis, as indicated by the laboratory markers, was associated with increased incidence of arrhythmias and unfavorable outcome of the disease.

Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...
