EKG Drugs
Question | Answer |
---|---|
Oxygen | Should be given to all patients with acute chest pain that may be due to ischemia, suspected hypoxemia of any cause, and cardiopulmonary arrest. |
Epinephrine | Indicated in the management of cardiac arrest. The chance of successful defibrillation is enhanced by administration of this drug and proper oxygenation. |
Isoproterenol (Isuprel) | Produces an overall increase in heart rate and myocardial contractility, but newer agents have replaced it in most clinical settings. It is contraindicated in the routine treatment of cardiac arrest. |
Dopamine (Intropin) | Indicated for significant hypotension in the absence of hypovolemia. |
Beta Blockers: Propranolol, Metoporolol, Atenolol, Esmolol | Reduce heart rate, blood pressure, myocardial contractility, and myocardial oxygen consumption which make them effective in the treatment of angina pectoris and hypertension. |
Lidocaine | The drug of choice for the suppression of ventricular ectopy, including ventricular tachycardia and ventricular flutter. Excessive doses can produce neurological changes, myocardial depression, and circulatory depression. |
Verapamil | Used in treatment of paroxysmal supraventricular tachycardia (PSVT), effective in terminating more than 90% of episodes of PVST in adults and infants. It is also useful in slowing ventricular response to atrial flutter and fibrillation. |
Digitalis | Increases the force of cardiac contraction as well as cardiac output. |
Morphine Sulfate | The traditional drug of choice for the pain and anxiety associated with acute myocardial infarction. In high doses, this drug may cause respiratory depression. It is a controlled substance and has a tendency for abuse and addiction. |
Nitroglycerin | A powerful smooth muscle relaxant effective in relieving angina pectoris. It is effective for both exertional and rest angina. Headache is a common consequence following the administration of this drug. |
