Summary
COVID-19 patients hospitalized with arrhythmias had higher mortality. Heart failure increased arrhythmia risk, and cardiac arrest during hospitalization resulted in death.
Area of Science:
- Cardiology
- Infectious Diseases
- Public Health
Background:
- Coronavirus disease 2019 (COVID-19) is linked to cardiovascular issues, including arrhythmias.
- Understanding these cardiac complications is crucial for patient management.
Purpose of the Study:
- To determine the incidence of cardiac arrhythmias and cardiac arrest (CA) in hospitalized COVID-19 patients.
- To identify risk factors and outcomes associated with these cardiac events.
Main Methods:
- Retrospective analysis of electronic medical records from a tertiary university-affiliated hospital.
- Inclusion of 241 consecutive COVID-19 patients.
Main Results:
- Cardiac arrhythmias occurred in 8.7% of patients, primarily atrial tachyarrhythmia.
- Patients with arrhythmias had significantly higher mortality (52.4% vs. 24.1%).
- Heart failure (HF) was the only independent predictor of arrhythmias (HR, 11.9).
- Cardiac arrest (CA) occurred in 3.3% of patients, all of whom died.
Conclusions:
- The incidence of cardiac arrhythmias in hospitalized COVID-19 patients was 8.7%, with atrial tachyarrhythmia being most frequent.
- Heart failure is a significant risk factor for developing arrhythmias in COVID-19 patients.
- Cardiac arrest in COVID-19 patients carries a very high mortality rate.

Mechanism of Cardiac Arrhythmias
1.3K
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Disturbances in Heart Rhythm
1.6K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.

ECG Interpretation of Arrhythmias I: Sinus Arrhythmias
499
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
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,...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Dysrhythmias III: Characteristics of Dysrhythmias
171
Dysrhythmias, also known as arrhythmias, are irregular heart rhythms that result from abnormal electrical activity in the heart, affecting its ability to circulate blood efficiently. Tachyarrhythmias, a subset of dysrhythmias, are characterized by abnormally fast heart rates exceeding 100 beats per minute. Here are some types of tachyarrhythmias with their distinct ECG features:Sinus Tachycardia:Sinus tachycardia presents a regular heart rhythm with an increased rate of 101-180 beats per...

Dysrhythmias V: Evaluating Dysrhythmias
151
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...
