What is lymphocytic myocarditis?
Lymphocytic myocarditis is a rare form of myocarditis that can result in hospitalization for acute care. It occurs when white blood cells (lymphocytes) enter and cause inflammation of the heart muscle. This condition can occur after a virus.
What is fulminant myocarditis?
Fulminant myocarditis (FM) is an uncommon syndrome characterized by sudden and severe diffuse cardiac inflammation often leading to death resulting from cardiogenic shock, ventricular arrhythmias, or multiorgan system failure. Historically, FM was almost exclusively diagnosed at autopsy.
How is pediatric myocarditis diagnosed?
Diagnosis of Myocarditis
- The most common test is a chest X-ray.
- An electrocardiogram can also give helpful clues if the diagnosis is suspected; however, the findings may be non-specific.
- An echocardiogram or heart ultrasound can be used to look at heart size and overall function.
What is transient myocarditis?
Subclinical myocarditis, without specific symptoms, may be inferred by transient increases in troponin (a biomarker of cardiac damage) or ECG, which measures the electrical activity of the heart, after an acute viral illness, adverse drug reaction, or rarely vaccination.
How do you diagnose lymphocytic myocarditis?
The diagnosis of myocarditis requires the presence of an inflammatory infiltrate as well as myocyte dropout, necrosis or degenerative changes. In this case of viral myocarditis, the infiltrate is predominantly lymphocytic.
How is myocarditis detected?
Tests to diagnose myocarditis might include: Electrocardiogram (ECG or EKG). This quick and painless test shows your heart’s electrical patterns and can detect irregular heartbeats. Chest X-ray.
What is giant cell myocarditis?
Giant cell myocarditis is a rare cardiovascular disorder that occurs for unknown reasons (idiopathic). It is characterized by inflammation of the heart muscle (myocardium), a condition referred to as myocarditis.
Does mild myocarditis go away?
Usually, a mild case of myocarditis will go away without any lasting damage. Severe cases may not be diagnosed until you have the symptoms of heart failure. Even severe cases may go away without notice, but these severe cases usually cause ongoing and irreversible damage to the heart muscle.
Does an ECG show myocarditis?
After a physical examination, your doctor might order one or more tests to confirm that you have myocarditis and determine its severity. Tests to diagnose myocarditis might include: Electrocardiogram (ECG or EKG). This quick and painless test shows your heart’s electrical patterns and can detect irregular heartbeats.
