|
inhitors/fibrinolysis |
•Protamine •reverseeffects of heparin. Conclusion of CABG |
|
Class Ia |
•Class I drugs•Inhibitfast sodium channels during depolarization (phase 0) |
|
Class Ia uses |
•Atrial Fibrillation/Flutter |
|
Ib |
•Less powerful Sodium blockers •Ischemic muscle – Lidocaine blocks ATP dependent channelsthus shortening ventricular repolarization•Lidocaine gtt to suppress VT storm |
|
ib uses |
VT
Local AnesthesiaSeizures Adverse EffectsAsystole; BradycardiaHypotensionNausea/Vomiting ContraindicationsWPW; SA/AV/Intraventricular Blocks |
|
Ic |
Most potent Sodium channel blockers Decrease speed of conduction of cardiac impulsesThis in turn may contribute to the proarrhythmic effects of these drugs Flecainide Propafenone Encainide moricizine |
|
Ic uses |
Atrial fibrillation |
|
II |
B-adrenergic antagonistDecrease rate of phase 4 depolarization which results in decreased autonomic nervous system activity Suppression of ventricular arrhythmia Prolongs p-r interval Decrease incidence of arrhythmia related morbidity/mortality Exact mechanism remains unclear |
|
III |
Potassium ion channel blockers
Prolongs cardiac depolarization/action potential duration/refractory period Decreases excitability of the myocardial cellsIbutilideDofetilide/tikosyn- must be hospitalized,loading over 3 days, Sotalol – used for more VT. Bretylium-no longer available in usAmiodarone( also NA channel blockade; B blocker and calcium channel blockade)( Class I, II and IV)PFTs, thyroid panals, Dronedarone (multaq)- Less lipophilic (results in shorter half life)Have to stop with acute heart failure- increased mortalityCan reintroduce once exacerbation has cleared up |
|
III uses |
•Atrial Fibrillation/Flutter•VT•SVT•WPW•Adverse Effects•Bradycardia;Torsade's de pointes; Proarrhythmic•Hypotension•Increasedmortality with CHF (Dronedarone)•PulmonaryToxicity; Thyroid Dysfunction; Parkinson like syndrome (rare) (amiodarone) |
|
IV |
Calcium channel blockers-inhibit inward slow calcium ion currents that may contribute to tachycardia. Non-Dihydropyridine (1st treatment for afib in er)VerapamilDiltiazemUsesRecurrent re-entry psvtAtrial fibrillation –reduce ventricular response rate Adverse Effects: Bradycardia/hypotension |
|
adenosine, |
adenosine •Inhibits sa node, atrial and av nodalconduction•Av node more sensitive than sa node•Plasma half life of 10 seconds•First line treatment for narrow complexsvt•Adverse effects:•Bradycardia,nausea, vomiting, ha, hypotension•Bronchoconstriction-asthmapts |
|
digoxin |
•Cardiac glycoside•Selective inhibitor of sodium pump•Helps to decrease automaticity at the avnode-prolongs the refractory period and slowing conduction through the node•Uses:•Atrialfibrillation; Heart failure- less common now•Common side effects:•Bradycardia,multiple drug interactions-dig toxicity |
