Summary
Wallenberg syndrome, a brainstem condition, can rarely cause sick sinus syndrome, a heart rhythm disorder. Early cardiac evaluation with a Holter monitor is crucial for detecting this potentially fatal complication.
Area of Science:
- Neurology
- Cardiology
Background:
- Wallenberg syndrome involves brainstem lesions, particularly in the medulla, affecting autonomic nervous system regulation.
- Cardiac arrhythmias are an uncommon but serious manifestation of Wallenberg syndrome.
Observation:
- A 55-year-old male diagnosed with Wallenberg syndrome presented with ataxia, ptosis, sensory deficits, and dizziness.
- During conservative treatment, the patient experienced intermittent palpitations requiring cardiac assessment.
Findings:
- Brain MRI confirmed a left dorsolateral medullary infarction, consistent with Wallenberg syndrome.
- A 24-hour Holter monitor revealed significant bradycardia and prolonged sinus pauses, indicative of sick sinus syndrome.
Implications:
- This case highlights sick sinus syndrome as a rare cardiac complication of Wallenberg syndrome.
- Routine ECG may miss sick sinus syndrome; 24-hour Holter monitoring is recommended for early detection in acute Wallenberg syndrome.
- Undiagnosed sick sinus syndrome poses a risk of sudden cardiac death, necessitating prompt medical intervention.

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

01:22Mitral Stenosis I: Introduction
25
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...

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
29
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
