What is the Na+, K+, & Ca2+ ion normal physiology of the heart?
1) The Na+/K+ pump exchanges 3K+ (moves inward) for 2Na+ (moves outward)
2) The Na+/Ca2+ antiporter exchanges Na+ (moves inward) for Ca2+ (moves outward)
3) K+ leak channels slowly allow K+ to diffuse (moves outward) to be used again by the
Na+/K+ pump (exchanger)
3) If the resting membrane potential reaches threshhold (approx +90mv) an AP occurs
What is the MOA and physiology leading to the effects of Digoxin?
1) Digoxin binds the K+ on the Na+/K+ pump preventing Na+/K+ exchange; K+ therefore stays outside the cell while Na+ stays inside the cell;
2) Na+ is then no longer exchanged with Ca2+; Ca2+ accumulates inside the cell;
3) Once threshhold is finally reached and an action potential does occur, the accumulated Ca2+ is released; release of an increased amount of Ca2+ results in an increased ionotropic effect (i.e. increased contractility due to increased ""ions"", Ca2+ in this case)
What is the c/u and rationale for Digoxin?
CHF b/c increases contractility
Atrial Fibrillation b/c slows conduction @ AV node leading to accumulation of intracellular Na+ which causes ventricles to contract harder (ventricular contractio is due to Na+)
What is the toxicity of Digoxin?
Torsades De Pointes Arrhythmia (i.e. prolonged QT) b/c of its effects on K+
Yellow vision
What is the tx for Digoxin toxicity?
1) STOP DIGOXIN ADMINISTRATION!
2) Slowly normalize K+
3) Lidocaine
4) Mg2+
5) Digifab/Digibind
6) Pacemaker once stable (~2wks later)
What effects does Digoxin have on the EKG?
Decr'd Na+/K+ Pump action --> Incr'd intracellular CA2+ accumulation:
PR Interval: Increased
QT Interval: Decreased
ST segment: Depression
T wave: Inversion (i.e. U wave)
What are the Class III anti-arrhythmics?
Ibutilide
Sotalol
Bretylium
Amiodarone
Dofetilide
What is the MOA and effects of Class III Anti-arrhythmics?
Blocks K+ leading to:
AP duration: Increased
QT interval: Increased (repolarization requires K+)
ERP: Increased (b/c blocked K+)
What is the break-down metabolite of Amiodarone?
Procainamide
What class of Anti-Arrhythmic is Procainamide?
Class IA
Why is Amiodarone listed as a Class IA AND Class III anti-arrhythmic?
Class IA: Amiodarone's metabolite, Procainamide, is a Class IA
Class III: Amiodarone's MOA is to block K+
What is the MOA & effects of Class IA Anti-arrhythmics?
Blocks Na+ AND K+ Channels leading to:
AP duration: Increased
QT interval: Increased (repolarization requires K+)
ERP: Increased (b/c blocked K+)
What are the Class IB Anti-arrhythmics?
Lidocaine
Mexlotine
Tocanimide

Phrophylaxis: Status-epilepticus seizures
What is the MOA of Phenytoin?
Blocks Na+ channels
What is the MOA and effects of Class IB Anti-arrhythmics?
Blocks Na+ (does NOT affect K+ channels):
AP duration: Decreased
QT interval: No change (repolarization requires K+ and there is no change in K+)
ERP: No change (b/c no change in K+)
What is the c/u for Class IB Anti-arrhythmics?
1) Post-MI Ventricular Arrhythmias
2) Lidicaine: 3rd step in tx for digioxin toxicity
What is the toxicity of Lidicaine?
ASYSTOLE --> DEATH
(MOA = blocks Na+ Channels in the heart)
What drugs tx Ventricular Arrhythmias and what is the rationale for their use?
Class IB Anti-arrhythmics:
Decreased AP = decreased work by the heart
Class III Anti-arrhythmics:
K+ is blocked, thereby slowing repolarization at the AV Node
(i.e. less ventricular firing)
What is the rationale for whether or not to use Digoxin for the tx of Ventricular Arrhythmias?
Digoxin could be used, but you do NOT want to make the heart contract harder. Therefore, Digixin is not used in the tx of Ventricular Arrhythmias
What are the Class IC drugs?
Cainide
Flecainide
Propafenone
What are the indications for Class IC Anti-arrhythmics?
When everything else fails!
Ventricular Tachycardia becomes Ventricutlar Fibrillation
Intractable SVT
What is the DOC for SVT?
DOC: Adenosine
2nd Line: Verapamil
What is the MOA of Adenosine?
Opens Ca2+ channels: decr'd Ca2+
Opens K+ channels: incr'd K+ (repolarization --> ""hyperpolarizes"" AV node)
Why are Class IC Anti-arrhythmics ONLY given for INTRACTABLE SVT?
Class IC Anti-arrhythmics block Na+ channels EVERYWHERE!!
The heart has once chance to ""fire"" & then it will not ""fire"" again (b/c Na+ is blocked)
What is the MOA and effects of Class IC Anti-arrhythmics?
Class IC Anti-arrhythmics block Na+ channels EVERYWHERE!!
AP duration: no more AP's after ""first fire""
QT interval: No change (repolarization requires K+ and there is no change in K+)
ERP: No change (b/c no change in K+)
Why do we use Class IC Anti-arrhythmics, if they are a "last resort"?
Toxicity = ""PRO-ARRHYTHMIA""
Any arrhythmia is better than NO arrhythmia at all (i.e. flutter or flatline)
e.g. working on pt for 20 mins & still no HR
What is the MOA of Class II Anti-arrhythmics?
Class II = B-Blockers:
Decr'd HR
Decr'd Contractility
Decr'd AV node conduction
What is the phsyiological bases for why Class II Anti-arrhythmics cause decr'd HR?
Class II = B-Blockers:
Beta receptors are blocked --> decr'd stimulation of Gs proteins --> decr'd AC -->
decr'd cAMP --> decr'd PKA --> decr'd SS outflow --> decr'd HR

(NOTE: Step 1 may ask which of the following is affected with B-Blocker tx & the correct answer will be one of the steps in the pathway)
Which B-Blockers have intrinsic sympathomimetic activity
