- lead I -ve and aVF +ve right axis deviation
- lead I +ve and aVF -ve

- lead II -ve left axis deviation
Right axis deviation

Condition PPM
Pure sustained AF VVI or VVIR
Pure sinus node dysfunction without evidence of AV block at rapid heart rates AF AAIR or DDDR
2nd or 3rd degree AVB Other bradyarrhythmia with visible p waves DDD or DDDR
- Pure ATRIAL PPM = if pure sinus node dis without AF (but may = AV nodal, therefore, most put in dual chamber)
- VENTRICULAR PPM = if slow atrial fibrillation = VVI
- All others = Dual Chamber with slow rate and visible 'p' waves
Heart block (Mobitz 2 + 3rd AVB) with :
- symptoms
- haemodynamic compromise
- asystole
- bilateral BBB
- following MI
- following cardiac surgery
MI
