1. normal -AVR & V1 leads show predominantly negative QRS complex
characteris- tics -T-wave upright in leads I & II
12 lead ecg -R-wave V1 will be small and increase in each chest lead as you
approach V5.
2. ischemia reduced blood flow - inverted T wave
3. injury acute tissue damage - change in ST segment
4. infarction necrosis/tissue death - significant Q waves
5. sinus treat other symptoms
