Results: Limited subendocardial ischemic zones caused small ST depression in ECG leads not overlying the ischemic region. An ischemic zone of 50% transmural extent covering the entire left ventricular subendocardium caused an ST-depression pattern similar to that observed during stress test. ...
The purpose of this study was to evaluate the long-term prognostic value of ST segment depression on the electrocardiogram (ECG) in patients with acute myocardial infarction. Background. The prognostic importance of ST depression on the ECG has been studied in small groups of patients with ...
She had unprovoked further increase in her heart rate up to 145 bpm, and during these episodes, her ECG displayed further ST segment depression up to 3 mm and of 0.12 second duration. An organic cause could not be found to explain her sinus tachycardia. Results of all laboratory ...
Clini-cal data including ECG , myocardial engzmes , coronary angiograms and left ventriculogram , postinfarction complicationsand hospital mortality rates were analyzed. Results: Patients with precordial ST segment depression in leads V 1 to V 6 had larger infarction size, more postinfarc-tion ...

Near maximal graded exercise tests and coronary angiograms were compared in 37 patients with a history of chest pain and with ST segment depression at rest, who were free of obvious nonischemic causes of ST depression. Additional ST depression of 0.1 mV or more occurred with exercise in 26 pa...
Background The new Universal Definition for Myocardial Infarction includes electrocardiographic (ECG) criteria for ischemia, specifying horizontal or down-sloping ST depression ≥0.05 mV in two contiguous ECG leads. Because these requirements are based on experience from studies prior to modern ECG technol...
A large reciprocal ST-segment depression in inferior leads and ST-segment depression in lead V5 are useful ECG findings allowing determination of STEMI due to an LMT lesion. 下导联ST段压低与V5导联ST段压低之间存在较大...

Results There was no correlation between ST-segment depression and coronary stenosis, r=0.078, P=0.366; positive correlation with lesion count, r=0.241, P=0.037. Conclusion The degree of ST segment depression in acute NSTEMI ECG is positively correlated with the number of coronary lesions. 【Key...
