Antiarrhythmics list
Atropine 4 brady (stops brakes), Adenosine first line 4 ST/SVT/AT/ and MONOVT (fast/liquid dfib 6-6-12 slows AV node), Cardizem 4 Afib/fltr (slows rate/sa and av conduction), Amioderone 4 monoVtach (prolongs abs refract period), Lidocaine 4 mono vtach (decreases irritibility) , Procainamide for monoVtach (slows vent conduction)
Class 1 antidysrrhythmics
SODIUM - 1A- slows sodium in cells: Pronestyl/procainamide- suppress ectopic foci- can prolong Qtinterval.
1B- LIDOCAINE- Blocks Sodium in Purkinje fibers
Class 2 antidysrhythmics
Beta Blocker (blocks chatacholemines epi and norepi)- METAPROLOL - reduces rate during myocardial ischemia and reduces myocardial 02 demand and reduces BP.
Class 3 antidysrhythmics
PotassiumChannel Blocker - Increase PHASE 1/2/3- for atrial and ventricular tachycardias- prolongs absolute refractory period AMIODERONE -
Class 4 antidysrhythmics
Calcium Channel Blocker - reduces BP, reduces HR by slowing conduction throuth SA and AV nodes, increases O2 to myocardial cells. SLOWS AV CONDUCTION- Verapamil and Diltiazem/CARDIZEM
Class 5 antidysrhythmics - the unknowns
ADENOSINE - the heart stopper - liquid DFIB, and Magnesium Sulfate -
Action Potential Pneumonics
