…glucose is reabsorbed by SGLT1 in the S3 segment. SGLT2 also mediates proximal tubular sodium reabsorption, with chloride following passively down the resulting electrochemical gradient…

…effect of the lesion. The apparent percentage stenosis is calculated relative to an adjacent reference segment presumed to be relatively normal. This assumption may be…

…2800 adults per 1 million individuals have congenital heart defects, and half of them have moderate or complicated defects; the remaining third have mild defects (…

…branch block, Wolff–Parkinson–White patterns or ventricular pacing STEMI and non ST segment elevation myocardial infarction (NSTEMI) are contemporary clinical and electrocardiographic categories. Earlier…

…ST segment to T wave is more abrupt in ischemia (the transition is normally smooth). Refer to Figure 2 . Figure 2. Transition from ST segment…

…Moreover, the ST segment may have a concave appearance if the T wave is prominent (such as in hyperkalemia, early repolarization or even early phases…

…to such ECG changes. It must also be noted that the J point is occasionally suboptimal for measuring ST segment deviation. This is explained by…

…and clinical applications of these modalities, the definitions of cardiac planes, ventricular segments, and coronary arterial territories evolved differently. This resulted in difficulties when comparing…
