WebThe PR segment elevation and depression The PR segment is not affected in STEMI, whereas acute pericarditis often causes PR segment depression. Such depressions occur in most leads, except from lead V1, which often shows PR segment elevation. Troponin leakage in acute pericarditis Elevated troponins are common in acute pericarditis. M. WebShort PR interval (i.e. PR interval shorter than 2nd percentile, see Normal values for Pediatric ECG) suggests pre-excitation. The principles of pre-excitation in children are the same as for adults. For details, refer to Pre-excitation and Wolff-Parkinson-White Syndrome. Prolonged PR interval suggests AV block.
