| Abstract |
|
Depression of the PR-segment is very specific of acute pericarditis and
represents subepicardial atrial injury due to pericardial inflammation. And the ST-segment
elevation that occurs during acute pericarditis shows usually upwardly concave appearance; and
helps distinguish pericarditis from early repolarization and acute myocardial infarction. Our
purpose of this study was to investigate the relation and feature of these two findings. Methods:
We conducted a 7-year retrospective study of acute pericarditis patients; who visited to our
center between January 2001 and December 2007. All standard initial 12-lead
electrocardiography were examined and compared the electrocardiographic findings according to
the first symptom time. And if the electrocardiography shows only PR-segment depression;
electrocardiographic change was investigated. Results: Thirteen patients included in this study. 5
patients had only PR-segment depression (group 1); 3 patients had both PR-segment depression
and ST-segment elevation (group 2); 2 patients had only ST-segment elevation (group 3) and 3
patients had no PR-segment and ST-segment deviation (group 4) on initial 12-lead electrocardiography. The mean times from the onset of symptoms to the first ECG were 6.80±
5.4; 188±56.7; 40±21.2; 263±205.5 hours. 3 patients showed ST-segment elevation among 5
patients; who had only PR-segment depression on the first electrocardiography. Conclusion: PRsegment
depression is the initial electrocardiographic finding in acute pericarditis and can precede
ST-segment elevation. PR-segment depression and classic ST-segment change are important in
diagnosing acute pericarditis. |
