The ST Segment represents the interval between ventricular depolarization and repolarization. The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction. Causes of ST Segment Elevation ----------------------------------------------------- Acute myocardial infarction Coronary vasospasm (Printzmetal’s angina) Pericarditis Benign early repolarization Left bundle branch block Left ventricular hypertrophy Ventricular aneurysm Brugada syndrome Ventricular paced rhythm Raised intracranial pressure Takotsubo Cardiomyopathy Patterns of ST Elevation --------------------------------------- Acute ST elevation myocardial infarction (STEMI) ST segment elevation and Q-wave formation in contiguous leads. Follow the links above to find out more about the different STEMI patterns.: Septal (V1-2) Anterior (V3-4) Lateral (I + aVL, V5-6) Inferior (II, III, aVF) Right ventricular (V1, V4R) Posterior (V7-9) There is usually reciprocal ST depression in the electrically opposite leads. For example, STE in the high lateral leads I + aVL typically produces reciprocal ST depression in lead III. Causes of ST Depression ----------------------------------------- Myocardial ischaemia / NSTEMI Reciprocal change in STEMIPosterior MI Digoxin effect Hypokalaemia Supraventricular tachycardia Right bundle branch block Right ventricular hypertrophy Left bundle branch block Left ventricular hypertrophy Ventricular paced rhythm #STsegment #STsegmentecg #STsegmentelevation #STsegmentdepression #ecgwaves #ecg #ekg #ecgcourse #ecgmadeeasy #ecgonline #ecgreading #ecginterpretation #ekgonline #howtoreadecg
