ST segment. Indicates early ventricular repolarization . Normally not depressed more than 0.5 mm . May be elevated slightly in some leads (no more than 1 mm) PR interval. Indicates AV conduction time . Duration time is 0.12 to 0.20 seconds . QT interval. Indicates repolarization time . General rule: duration is less than half the preceding R-R ...

An ECG of Martha’s heart demonstrated an elevated ST segment. What are the physiological effects of myocardial ischemia that produce this finding? What variables affect the ECG tracing of a patient with ACS? What are the benefits of administering fibrinolytic therapy, nitroglycerin, and oxygen in the early management of STEMI? ...
ST-Segment Elevation Myocardial Infarction
ST Segment Abnormalities. Causes of an Elevated ST Segment. Note that ST segment elevation is measured from the iso-electric line to the J point. The iso-electric point (line) is taken as the ECG trace between beats, (ie the end of the T wave to the beginning of the next P wave) 4. 1. ST segment elevation myocardial infarction

ST Segment : The segment between the end of the QRS complex and the . beginning of the T wave. Normally it is isoelectric at baseline, but may be elevated or depressed in a variety of conditions. T Wave : A deflection that represents ventricular repolarisation or . recovery. It appears after the QRS complex.

ST segment. The ST segment marks the beginning of ventricular repolarization. Absolute refractory period- can not have a response. Point of end of QRS complex and beginning os ST segment is J point. From end of QRS to beginning of T wave. Depression >1mm is myocardial ischemia. Elevation >1mm possible myocardial damage or injury. T waves

An EKG showed 3mm ST segment elevations in V1-V4 and a CXR showed an enlarged heart and pulmonary vascular redistribution. He was immediately given aspirin, sublingual nitroglycerin, furosemide, and supplemental oxygen with prompt resolution of his symptoms, output of 1 liter of urine, improvement in his oxygenation, and normalization of his EKG.

ST SEGMENTS. I. ST SEGMENT ELEVATION - Normal ST segment: at baseline (same level as the PR segment) - Subtle ST segment elevation is frequently seen in V1-V3, especially in men; may be normal - The ST segment is the smoothest segment in the ECG; all notches are suggestive of P waves
