St elevation chest leads
網頁This is the first report to the best of my knowledge describing a patient with Wellens’ syndrome having chest pain accompanied by bifid T waves in precordial leads without significant ST segment elevation or Q waves in the electrocardiogram, and Enter the email 網頁2002年4月4日 · It is unusual for ST segment elevation in lead V1 to occur as an isolated phenomenon. Right sided chest leads are much more sensitive to the presence of right ventricular infarction. The most useful lead is lead V4R (an electrode is placed over the right fifth intercostal space in the mid-clavicular line).
