Figure 1A Standard leads obtained four years previously showing increased voltage but normal ST-T contour. B. Standard leads obtained at time of admission prior to development of repetitive ventricular fibrillation showing marked peaking of T waves in almost all leads. The T waves are much taller than QRS complexes in precordial leads. CHEST 1980 78, 660-663DOI: (10.1378/chest.78.4.660) Copyright © 1980 The American College of Chest Physicians Terms and Conditions
Figure 2A Baseline ECG of experimental dog prior to infusion of sodium fluoride. B. Tracing taken 55 minutes later showing marked peaking of T waves in almost all leads. These changes were apparent after 30 minutes of infusion. Potassium levels in both experimental animals were always elevated when these T wave changes appeared, 6.9 mEq/L in this instance.
