Summary
Six months after coronavirus infection, patients showed improved general condition and reduced heart rhythm disorders, with autonomic nervous system recovery. However, subtle left ventricular diastolic dysfunction and reduced systolic velocity persisted in moderate to severe cases.
Area of Science:
- Cardiology
- Infectious Diseases
- Pulmonology
Context:
- Coronavirus infection can lead to persistent cardiovascular complications.
- Long-term effects on myocardial function and heart rhythm require thorough investigation.
Purpose:
- To assess cardiohemodynamic alterations and heart rhythm disorders at 3 and 6 months post-coronavirus infection.
- To evaluate changes in patients with varying pneumonia severity.
Summary:
- Echocardiography, ECG Holter monitoring, and Doppler ultrasonography were used in 77 patients.
- Improvements in general condition and reduced arrhythmias were observed at 6 months.
- While right heart and hepatolienal blood flow normalized in moderate/severe cases, occult left ventricular diastolic dysfunction and reduced segmental systolic velocity persisted.
Impact:
- Highlights the long-term cardiovascular sequelae of coronavirus infection.
- Identifies persistent subclinical myocardial dysfunction despite overall recovery.
- Informs clinical monitoring and management strategies for post-coronavirus patients.

01:28Mechanism of Cardiac Arrhythmias
1.0K
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.

01:16ECG Interpretation of Arrhythmias I: Sinus Arrhythmias

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,...

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.

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

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, 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...
