The pericardium is electrically silent, and so true acute pericarditis should not be associated with ECG changes. STE actually implies concurrent involvement of the myocardium; i.e. myopericarditis. The greater the degree of myocardium involved, the more ECG changes will develop, including STE, AV blocks, and dysrhythmias. Additionally, myocardial involvement is implied by elevated troponin levels, the magnitude of which is related to the amount of myocardial involvement.
