Summary
Brucellosis can cause rare cardiac complications like complete atrioventricular (AV) block. This case highlights the need for careful cardiac evaluation in brucellosis patients, even when initial treatments fail.
Area of Science:
- Cardiology
- Infectious Diseases
- Internal Medicine
Background:
- Brucella infection presents with diverse multi-system involvement, commonly affecting the cardiovascular system.
- Infective endocarditis is the most frequent cardiovascular complication of brucellosis.
- Conduction abnormalities are rarely reported in cardiac Brucella infections.
Purpose of the Study:
- To report a rare case of complete atrioventricular (AV) block in a pediatric patient with Brucella infection.
- To emphasize the importance of cardiac evaluation in patients diagnosed with brucellosis.
Main Methods:
- A case report of an eight-and-a-half-year-old male with Brucella infection.
- Diagnosis involved clinical presentation, electrocardiogram (ECG), 24-hour Holter monitoring, echocardiography, and serological testing.
- Treatment included antibiotics and, ultimately, pacemaker implantation due to persistent AV block.
Main Results:
- The patient presented with fever, arthralgia, and splenomegaly, initially unresponsive to treatment.
- ECG and Holter monitoring revealed complete atrioventricular (AV) block with a heart rate of 46-48 bpm.
- Despite antibiotic therapy, the AV block persisted, necessitating a permanent pacemaker.
Conclusions:
- Complete AV block is an extremely rare complication of Brucella infection.
- Cardiac involvement, including rhythm abnormalities, can have significant outcomes in brucellosis.
- Brucellosis patients require thorough cardiac assessment to detect and manage potential complications.

724
Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

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.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

735
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

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...

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
