2. 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.

3. 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.
