What are the ECG findings in a MI?
Q waves, ST elev, inverted T wav
Name the heart block :
1) no relationship between P waves and QRS compled
2) long PR int, P waves present
3) QRS does not follow each P
1) 3rd deg
2) 1st deg
3) 2nd deg
Mobitz I vs Mobitz II
I) QRS does NOT follow each P, PR int inc progressively
II) PR steady, irreg P waves
