Significance of Abnormal T Waves in Acute Coronary Syndrome without ST Changes in ECG
Rajiv Arora, Aafreen Arora

ABSTRACT:
Background:Acute coronary syndrome (ACS) refers to any group of clinical symptoms compatible with acute myocardial ischemia and includes unstable angina (UA), non—ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI).Hence; the present study was undertaken for assessing the significance of Abnormal T Waves in Acute Coronary Syndrome without ST Changes in ECG. Materials & methods:A total of 100 patients who reported to the department with unstable angina pectoris were enrolled in the present study. Inclusion criteria for the present study included patients without ST-segment deviation in ECG with following electrocardiographic findings of T wave abnormality. During the acute stage, continuous ECG recording was done during the first hour of the admission, followed by ECG recording for every 30 minutes for next four hours. All the ECG findings were recorded in Microsoft excel sheet and were analysed by SPSS software. Results: Sensitivity and specificity of abnormal T waves in detection of coronary artery stenosis was found to be 95 percent and 90 percent respectively. Conclusion: T-wave abnormalities are crucial ECG occurrences in subjects with non–ST-segment elevation ACS and often correlated with coronary artery obstruction.
