Transcript

  • 1. INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  • 2. Dysrhythmia  Any deviation from the normal rhythm of the heart Antidysrhythmics  Drugs used for the treatment and prevention of disturbances in cardiac rhythm www.indiandentalacademy.com
  • 3.  Inside the cardiac cell, there exists a net negative charge relative to the outside of the cell. www.indiandentalacademy.com
  • 4.     This difference in the electronegative charge. Results from an uneven distribution of ions (sodium, potassium, calcium) across the cell membrane. An energy-requiring pump is needed to maintain this uneven distribution of ions. Sodium-potassium ATPase pump www.indiandentalacademy.com
  • 5. www.indiandentalacademy.com
  • 6.  A change in the distribution of ions causes cardiac cells to become excited.  The movement of ions across the cardiac cell’s membrane results in the propagation of an electrical impulse.  This electrical impulse leads to contraction of the myocardial muscle. www.indiandentalacademy.com
  • 7. Four Phases  The SA node and the Purkinje cells each have separate action potentials. www.indiandentalacademy.com
  • 8. www.indiandentalacademy.com
  • 9.  System commonly used to classify antidysrhythmic drugs www.indiandentalacademy.com
  • 10.  Class 1        Class Ia Class Ib Class Ic Class II Class III Class IV Other www.indiandentalacademy.com
  • 11. Class I    Membrane-stabilizing agents Fast sodium channel blockers Divided into Ia, Ib, and Ic agents, according to effects www.indiandentalacademy.com
  • 12. Class I moricizine    General Class I agent Has characteristics of all three subclasses Used for symptomatic ventricular and life-threatening dysrhythmias www.indiandentalacademy.com
  • 13. Class Ia quinidine, procainamide, disopyramide     Block sodium channels Delay repolarization Increase the APD Used for atrial fibrillation, premature atrial contractions, premature ventricular contractions, ventricular tachycardia, Wolff-Parkinson-White syndrome www.indiandentalacademy.com
  • 14. Class Ib tocainide, mexiletine, phenytoin, lidocaine     Block sodium channels Accelerate repolarization Decrease the APD Used for ventricular dysrhythmias only (premature ventricular contractions, ventricular tachycardia, ventricular fibrillation) www.indiandentalacademy.com
  • 15. Class Ic encainide, flecainide, propafenone     Block sodium channels (more pronounced effect) Little effect on APD or repolarization Used for severe ventricular dysrhythmias May be used in atrial fibrillation/flutter www.indiandentalacademy.com
  • 16. Class II Beta blockers: atenolol, esmolol, petaprolol, propranolol    Reduce or block sympathetic nervous system stimulation, thus reducing transmission of impulses in the heart’s conduction system Depress phase 4 depolarization General myocardial depressants for both supraventricular and ventricular dysrhythmias www.indiandentalacademy.com
  • 17. Class III amiodarone, bretylium, sotalol, ibutilide      Increase APD Prolong repolarization in phase 3 Used for dysrhythmias that are difficult to treat Life-threatening ventricular tachycardia or fibrillation, atrial fibrillation or flutter—resistant to other drugs Sustained ventricular tachycardia www.indiandentalacademy.com
  • 18. Class IV verapamil, diltiazem    Calcium channel blockers Depress phase 4 depolarization Used for paroxysmal supraventricular tachycardia; rate control for atrial fibrillation and flutter www.indiandentalacademy.com
  • 19. Other Antidysrhythmics digoxin, adenosine  Have properties of several classes and are not placed into one particular class www.indiandentalacademy.com
  • 20. Digoxin  Cardiac glycoside  Inhibits the sodium-potassium ATPase pump  Positive inotrope—improves the strength of cardiac contraction  Allows more calcium to be available for contraction  Used for CHF and atrial dysrhythmias  Monitor potassium levels, drug levels, and for toxicity www.indiandentalacademy.com
  • 21. adenosine (Adenocard)       Slows conduction through the AV node Used to convert paroxysmal supraventricular tachycardia to sinus rhythm Very short half-life Only administered as fast IV push May cause asystole for a few seconds Other side effects minimal www.indiandentalacademy.com
  • 22. ALL antidysrhythmics can cause dysrhythmias!!  Hypersensitivity reactions       Nausea Vomiting Diarrhea Dizziness Blurred vision Headache www.indiandentalacademy.com
  • 23.    Obtain a thorough drug and medical history. Measure baseline BP, P, I & O, and cardiac rhythm. Measure serum potassium levels before initiating therapy. www.indiandentalacademy.com
  • 24.    Assess for conditions that may be contraindications for use of specific agents. Assess for potential drug interactions. Instruct patients regarding dosing schedules and side effects to report to physician. www.indiandentalacademy.com
  • 25.    During therapy, monitor cardiac rhythm, heart rate, BP, general well-being, skin color, temperature, heart and breath sounds. Assess plasma drug levels as indicated. Monitor for toxic effects. www.indiandentalacademy.com
  • 26.    Instruct patients to take medications as scheduled and not to skip doses or double up for missed doses. Patients who miss a dose should contact their physician for instructions if a dose is missed. Instruct patients not to crush or chew any oral sustained-release preparations. www.indiandentalacademy.com
  • 27.   For class I agents, monitor ECG for QT intervals prolonged more than 50%. IV infusions should be administered with an IV pump. www.indiandentalacademy.com
  • 28.  Patients taking propranolol, digoxin, and other agents should be taught how to take their own radial pulse for 1 full minute, and to notify their physician if the pulse is less than 60 beats/minute before taking the next dose of medication. www.indiandentalacademy.com
  • 29.  Monitor for therapeutic response: Decreased BP in hypertensive patients  Decreased edema  Regular pulse rate or  Pulse rate without major irregularities, or  Improved regularity of rhythm  www.indiandentalacademy.com
