St elevation chest leads
網頁2024年4月20日 · Cocaine is considered a leading non-opioid cause of drug overdose in the US. It acts as a sympathomimetic and increases the amount of catecholamines, thereby increasing the risk of ventricular irritability and resultant arrhythmias. Its sodium (Na) channel blockage is the principal mechanism behind the Brugada pattern on an electrocardiogram … 網頁Chest leads that detect this ST vector will display ST segment depressions (because the ST vector heads away from these leads). However, leads with ST segment depressions do not necessarily reflect the ischemic area; e.g ST segment depressions in leads V3 and V4 do not necessarily imply that the ischemia is located anteriorly.

網頁The ST elevations are most pronounced in the chest leads and they are accompanied by prominent T-waves. Virtually all patients with early repolarization display ST segment elevation. The hallmark of early repolarization is the end-QRS notch (a notch in the J point) or the end-QRS slur (the final slurring part of the R-wave).
