Insights
The COVID-19 pandemic has led to cardiac complications, including arrhythmia, in patients. Understanding the mechanisms of these heart rhythm disorders is crucial for effective patient management.
Area of Science:
- Cardiology
- Infectious Diseases
- Critical Care Medicine
Background:
- The COVID-19 pandemic has significantly impacted healthcare, particularly concerning cardiovascular complications.
- Cardiac arrhythmia and arrest are frequently observed in intensive care unit patients with COVID-19.
Purpose of the Study:
- To review the association between COVID-19 infection and cardiac arrhythmias.
- To detail the potential pathophysiological mechanisms underlying tachyarrhythmia and bradyarrhythmia in COVID-19 patients.
Main Methods:
- This study is a review of existing literature on COVID-19 and cardiac arrhythmias.
- The review focuses on identifying and explaining the mechanisms linking viral infection to heart rhythm disturbances.
Main Results:
- Cardiac arrhythmias in COVID-19 patients are linked to hypoxia, cytokine storm, myocardial ischemia, and inflammatory conditions like congestive heart failure.
- Both rapid (tachyarrhythmia) and slow (bradyarrhythmia) heart rhythm disorders are prevalent.
Conclusions:
- Understanding the occurrence and mechanisms of cardiac arrhythmias in COVID-19 is essential for appropriate clinical management.
- Further research into these mechanisms can guide therapeutic strategies for affected patients.
Abstract:
The coronavirus disease 2019 (COVID-19) pandemic has presented substantial challenges for providing health care due to the numerous complications on the respiratory and cardiovascular systems of people. Cardiac arrhythmia is one of the cardiac complications, and it was observed in COVID-19 patients. Moreover, arrhythmia and cardiac arrest are common in COVID-19 patients in the intensive care unit. The occurrence of cardiac arrhythmia in COVID-19 patients is associated with hypoxia, cytokine storm, myocardial ischemia and inflammatory disease such as congestive heart failure. It is necessary to know the occurrence and mechanisms of tachyarrhythmia and bradyarrhythmia in patients with COVID-19 infection for their proper management. This review provides an overview of the association between COVID-19 and arrhythmias by detailing possible pathophysiological mechanisms.

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,...
