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. WebThe PR interval is usually prolonged when the electrical signal takes a long time to get through the AV node, as seen in a first-degree atrioventricular (AV) block. The AV node is the “gatekeeper” that sends an electrical signal from the top of the heart to the bottom. philipp endler crailsheim
