Views Read Edit View history. 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. Retrieved from ” https: Defibrillation uses farmacloogica therapeutic dose of electric current to the heart at farmacoloica random moment in the cardiac cycleand is the most effective cardioversiom measure for cardiac arrest associated with ventricular fibrillation and pulseless ventricular tachycardia.

In other projects Wikimedia Commons. When synchronized electrical cardioversion is performed as an elective procedure, the shocks can be performed in conjunction with drug therapy until sinus rhythm is attained. Flecainidemoricizine and propafenone are Class Ic agents. 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.

Faramcologica pads are placed on the chest of the patient, or one is placed on the chest and one on the back. However, if the patient is hemodynamically unstable or unconscious, the shock is given immediately upon confirmation of the arrhythmia.

A cardoiversion history of cardiac insufficiency was nonsignificantly less common in patients who converted with vernakalant 6. Articles needing additional references from September All articles needing additional references. Having no prior history of AF was nonsignificantly related to greater effectiveness in Drugs that cardiioversion effective at maintaining cardioversio rhythm after electric cardioversion can also be used for pharmacological cardioversion.

Class Ic greatly slow phase 0 depolarization in the ventricles however unlike 1a have no effect on the refractory period. Pericardium Pericardiocentesis Pericardial window Pericardiectomy Myocardium Cardiomyoplasty Dor procedure Septal myectomy Ventricular reduction Alcohol septal ablation Conduction system Maze procedure Cox maze and minimaze Catheter ablation Cryoablation Radiofrequency ablation Pacemaker insertion Left atrial appendage occlusion Cardiotomy Heart transplantation.

They work by inhibiting the action potential of the SA and AV nodes.

After the procedure, the patient is monitored to ensure stability of the sinus rhythm. Not all beta blockers are the same; some are cardio selective affecting farmacilogica beta 1 receptors while others are non-selective affecting beta 1 and 2 receptors.

Duration less than 12 hours was significantly associated with greater effectiveness Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks referred to as defibrillation.

They also decrease cardiac oxygen demand and can prevent cardiac remodeling.

Impedance cardiography Ballistocardiography Cardiotocography. Pharmacological cardioversion is an especially good option in patients with fibrillation of recent onset.

To perform synchronized electrical cardioversion, two electrode pads are used or, alternatively, the traditional hand-held cardiovefsioneach comprising a metallic plate which is faced with a saline based conductive gel. If the patient is stable, adenosine may be administered first, as the medicine performs a sort of “chemical cardioversion” and frmacologica stabilize the heart and let it resume normal function on its own without using electricity.

The median time to conversion was 8 minutes after a first dose and 34 minutes after a second dose. Marino’s the ICU book Fourth edition. There are various classes of agents that are most effective for pharmacological cardioversion.

Procainamidequinidine and disopyramide are Class Ia agents. Valve repair Valvulotomy Mitral valve repair Valvuloplasty aortic mitral Valve replacement Aortic valve repair Aortic valve replacement Ross procedure Percutaneous aortic valve replacement Mitral valve replacement production of septal defect in heart enlargement of existing septal defect Atrial septostomy Balloon septostomy creation of septal defect in heart Blalock—Hanlon procedure shunt from heart chamber to blood vessel atrium to pulmonary artery Fontan procedure left ventricle to aorta Rastelli procedure right ventricle to pulmonary artery Sano shunt compound procedures for transposition of great vessels Arterial switch operation Mustard procedure Senning procedure for univentricular defect Norwood procedure Kawashima procedure shunt from blood vessel to blood vessel systemic circulation to pulmonary artery shunt Blalock—Taussig shunt SVC to the right PA Glenn procedure.

Beta blockers that target the farrmacologica receptor are called cardio selective because beta-1 is responsible for increasing heart rate; hence a beta blocker will slow the heart rate. A synchronizing function either manually farmacologicca or automatic allows the cardioverter to deliver a reversion shock, by way of the pads, of a selected amount of electric current over a cwrdioversion number of cardioversino at the optimal moment in the cardiac cycle which corresponds to the R wave of the QRS complex on the ECG.

Prospective multicenter cohort study enrolling consecutive patients who were administered vernakalant for medical cardioversion of AF between September through March in 5 hospitals in the Spanish autonomous community of Valencia. They include lidocainemexiletine and phenytoin.

It has been shown to be effective in acute cardioversion of recent-onset atrial fibrillation and atrial flutter.

Ibutilide is another Class III agent but has a different mechanism cardioverwion action acts to promote influx of sodium through slow-sodium channels.
