What Causes St Segment Depression

The most important cause of st segment abnormality elevation or depression is myocardial ischaemia or infarction. Pseudo st depression wandering baseline due to poor skin electrode contact physiologic j junctional depression with sinus tachycardia most likely due to atrial repolarization. Subendocardial ischemia or even infarction.

Results in prolonged qt hypermagnesemia increased t wave amplitude hypercalcemia short t wave with shortened qt.

What causes st segment depression. Subendocardial means non full thickness ischemia. Otherwise ischemia is unlikely to be the cause of the st segment depression. The st segment can become elevated or depressed. The st segment represents the interval between ventricular depolarization and repolarization.

St segment depressions caused by ischemia are characterized by a horizontal or downsloping st segment. Indeed north american and european guidelines assert that the st segment must be either downsloping or horizontal. Hypokalemia st segment depression t wave flattening hyperkalemia multiple possible changes. The st segment is the flat isoelectric section of the ecg between the end of the s wave the j point and the beginning of the t wave.

St segment depression due to acute myocardial ischemia. Depression of the st segment and inversion of the t wave are common electrocardio graphic abnormalities. Secondary st segment depressions occur in the following conditions. We have no idea how serious this is causes of st depression.

Reciprocal change in stemi. Non q wave myocardial infarction reciprocal changes in acute q wave myocardial infarction e g st depression in. Myocardial ischemia nstemi. When severe classic finding is peaked t waves hypomagnesemia flat wide t waves.

St segment depression can occur during adenosine myocardial perfusion imaging and is an independent predictor of subsequent cardiac events and worse outcome particularly in association with ischemic defects. Left ventricular hypertrophy right ventricular hypertrophy left bundle branch block right bundle branch block pre excitation pacemaker stimulation in the right ventricle. Causes of st segment depression include myocardial ischemia digoxin effect ventricular hypertrophy acute posterior myocardial infarction pulmonary embolus left bundle branch block. T wave inversion in the anterior precordial leads may be seen in cases of acute pulmonary embolism while flat tened t waves with prominent u waves and st segment depression may reflect hypokalemia or digitalis therapy.

Other ischemic heart diseases causing st depression include. In contrast st elevation. Differential diagnosis of st segment depression normal variants or artifacts.
