Special Conditions	(index)
COPD - RAD (negative Lead I), low voltage, P pulmonale (RAH), +- RBBB Hyperkalemia - peaked T's, wide flat P, wide QRS, prolonged PR absent P, sine waves, arrhythmias, asystole Hypokalemia - flat or T waves, U waves, U > T waves, ST depression, tachyarrythmias Hypercalcemia - short QT Hypocalcemia - prolonged QT Pericaditis - flat or concave ST elevation (precordial and ? limb leads), +- low voltage, +- inverted T waves. Digitalis Toxicity - SA Block, AV Blocks, variable TC's, Junctional TC's, PVC's, Bigeminy, Trigeminy, VT, VFib, increased automaticity Quinidine - wide notched P, wide QRS, ST depression, prolonged PR and QT, U wave. Toxicity - SA-AV-Ventr. blocks, ectopy, VT Hypothyroidism - sinus BC, low voltage, ST depression, flat or (dec) T's. Hyperthyroidism - sinus TC, enlarged amplitudes with thyrotoxicosis. Hypothermia - (<36° C, <97° F): prolonged intervals (PR,QRS, QT), Osborn waves (J point parallels QRS).
