Electrocardiogram
ECG changes depend on the structures involved and the extent. Following ECG changes may be noted in patients with rhumatic fever[1].
- Sinus tachycardia or bradycardia depending on vagal tone.
- Prolongation of PR interval may be noted in some patients.
- Variable degree of AV conduction block may be noted. But they generally resolve with the resolution of rheumatic fever.
- P mitrale may be noted, which is suggestive of left atrial enlargement secondary to mitral valve abnormalities.
- Mital valve abnormalities may lead to development of atrial flutter or atrial fibrillation.
- T-wave inversions in may be noted in leads I, II and IV suggestive of pericardial invlovement.
- ST segment elevation may also be present in leads II, III, aVF and V4 to V6 in patients with acute pericarditis.
