2023年7月25日 · Myocarditis can result in conduction disturbances in the heart. Therefore, an electrocardiogram (EKG) is necessary. An EKG can show varying forms of heart block including first-degree, second-degree, or third-degree AV block.

2023年3月1日 · Rheumatic endocarditis is a common RHD variant that gradually deteriorates the normal function of the heart valves. RHD can be diagnosed using standard echocardiography or listened to as a heart murmur using a stethoscope. The electrocardiogram (ECG), on the other hand, is critical in the study and identification of heart rhythms and abnormalities.

2020年10月30日 · The WHF has well-defined minimal echocardiography criteria for the diagnosis of RHD, while the American Society of Echocardiography/American College of Cardiology/American Heart Association guidelines further outline well-recognized criteria for quantification of degree of regurgitation or stenosis.

2021年1月1日 · ECG with classical findings of chronic RHD with severe mitral regurgitation. The ECG shows sinus rhythm with right axis deviation, biatrial dilatation, right ventricular hypertrophy, and right ventricular strain in the setting of severe pulmonary hypertension from left heart disease (see main text for further details).

2017年3月10日 · Acute rheumatic fever (ARF) results from the body’s autoimmune response to a throat infection caused by Streptococcus pyogenes, also known as the group A Streptococcus bacteria. Rheumatic heart disease (RHD) refers to the long-term cardiac damage caused by either a single severe episode or multiple recurrent episodes of ARF.

On electrocardiogram, rheumatic fever is characterized by PR interval prolongation, conduction abnormalities, arryhthmias, or P mitrale depending on the structures involved and the extent of cardiac damage.

RHD can be diagnosed using standard echocardiography or listened to as a heart murmur using a stethoscope. The electrocardiogram is critical in the study and identification of heart rhythms and abnormalities. The effectiveness of ECG to identify distinguishing signs of RHD, however, has not been adequately examined.

2021年2月2日 · In chronic RHD, the ECG is normal with mild-to-moderate mitral regurgitation. Moderate-to-severe disease often leads to classic ECG findings of left atrial enlargement with upright P waves in lead I, a bifid P wave in leads V1–V6 that gives the “M” pattern of P-mitrale.

2019年10月7日 · Early clinical diagnosis is key, the updated Jones criteria increases the likelihood of diagnosis in endemic settings, including the echo diagnosis of sub-clinical carditis, polyarthralgia and monoarthritis as well as amended thresholds of minor criteria.

Echocardiography screening based on World Heart Federation echocardiographic criteria holds promise to identify patients earlier, when prophylaxis is more likely to be effective; however, several important questions need to be answered before this can translate into public policy.
