Drugs like amiodaronediltiazemverapamil and metoprolol are frequently given before cardioversion to decrease the heart rate, stabilize the patient and increase the chance that cardioversion is successful.

Se notificaron eventos adversos en 30 pacientes. Class IV drugs are calcium Ca channel blockers. A prior history of cardiac insufficiency was nonsignificantly less common in patients who converted with vernakalant 6. Cardioversion is a medical procedure by which an abnormally fast heart rate tachycardia or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs.

We studied cases. These are connected by cables to a machine which has the combined functions of an ECG display screen and the electrical function of a defibrillator. After the procedure, the patient is monitored to ensure stability of the sinus rhythm.

The median time to conversion was 8 minutes after a first dose and 34 minutes after a second dose. There are various classes of agents that are most effective for pharmacological cardioversion. Not all beta blockers are the same; some are cardio selective affecting only beta 1 receptors while others are non-selective affecting beta 1 and 2 receptors. Electrical therapy is inappropriate for sinus tachycardiawhich should always be a part of the differential diagnosis.

They also decrease farmacoloogica oxygen demand and can prevent cardiac remodeling. Flecainidemoricizine and propafenone are Class Ic agents. Defibrillation uses a therapeutic dose of electric current to the heart at a random moment in the cardiac cycleand is the most effective resuscitation measure for cardiac arrest associated with ventricular fibrillation and pulseless ventricular tachycardia. This article needs additional citations for verification. It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardiawhen a pulse is present.

Class Ic greatly slow phase 0 depolarization in the farjacologica however unlike 1a have no effect on the refractory period.

Cardioversion

From Wikipedia, the free encyclopedia. Beta blockers that target the beta-1 receptor are called cardio selective because beta-1 is responsible for increasing heart rate; hence a beta blocker will slow the heart cardiogersion.

Views Read Edit View history. Various antiarrhythmic agents can be used to return the heart to normal sinus rhythm. September Learn how and when to remove this template message. Duration less than 12 hours was significantly associated with greater effectiveness Timing the shock to the R wave prevents the delivery of the shock during the vulnerable period or relative cardioversioj period of the cardiac cyclewhich could induce ventricular fibrillation.

Unsourced material may be challenged and removed. Cardioversion with vernakalant was effective in To perform synchronized electrical cardioversion, two xardioversion pads are used or, alternatively, the traditional hand-held “paddles”each comprising a metallic plate which is faced with a saline based conductive gel.
