The T wave is usually of normal width but can be narrow based if there is coexistent (moderate) hyperkalemia (Fig. 94-30a), most often seen in patients with chronic renal failure (Fig. 94-30b). A very marked subendocardial ischemia (with the so-called hyperacute ST-T changes) can pr...

In patients with moderate prevalence and with exception of disturbing factors, a high positive and negative predictive value (more than 95%) can be expected if both ischemic indicators (ST depression + angina pectoris) are used.A.BergL.Samek...
