Can myocarditis be detected on ECG?

After a physical examination, your doctor might order one or more tests to confirm that you have myocarditis and determine its severity. Tests might include: Electrocardiogram (ECG). This noninvasive test shows your heart’s electrical patterns and can detect abnormal rhythms.

How does myocarditis present on ECG?

The ECG findings most commonly seen in myocarditis are: Sinus tachycardia. Diffuse T wave inversions. ST segment elevation without reciprocal depression.

Can you see myocarditis on MRI?

MRI can also play an important role in the diagnosis of the chronic phase of myocarditis such as the aetiology of DCM. As noted earlier, CM can be divided into chronic active myocarditis and chronic persistent myocarditis.

How long do symptoms of myocarditis last?

Acute: Symptoms appear rapidly and usually decrease after a week or two. Chronic: Slow appearance of symptoms that last greater than two weeks.

What are the results of an ECG for myocarditis?

ECG findings may include AV block, ventricular or supraventricular arrhythmia, and ST changes, including severe elevation mimicking acute myocardial infarction. Except for more severe cases, echocardiography typically shows normal systolic wall motion or just mild regional dysfunction.

How is cardiac magnetic resonance used to diagnose myocarditis?

A, Cine cardiovascular magnetic resonance (CMR) images in 3 short-axis views in diastole ( top) and systole ( bottom) in a patient with suspected active myocarditis. Note multiregional hypokinesis/lack of systolic wall thickening (arrowheads) and mild pericardial effusion (arrows). A movie is available in the online-only Data Supplement.

What are the signs and symptoms of myocarditis?

Symptoms are not specific; patients may present with chest pain, fatigue, dyspnea, or arrhythmia. ECG findings may include AV block, ventricular or supraventricular arrhythmia, and ST changes, including severe elevation mimicking acute myocardial infarction.

What are the CMR criteria for active myocarditis?

On the basis of available research and expert consensus, diagnostic CMR criteria have been proposed (Lake Louise Criteria) 16 that are also part of societal publications 17, 18 and include CMR criteria for hyperemia, edema, and necrosis ( Table 1 ). If 2 of 3 criteria are positive, the CMR scan is indicative of active myocarditis. 16
