antiarrhythmic

[-ərith′mik]
Etymology: Gk, anti + rhythmos, rhythm
1 pertaining to a procedure or substance that prevents, alleviates, or corrects an abnormal cardiac rhythm.
2 an antiarrhythmic agent. A defibrillator that delivers a precordial electric shock is often used to restore a normal rhythm to rapid, irregular atrial or ventricular contractions. A pacemaker may be implanted in a patient with an extremely slow heart rate or another arrhythmia. The electrode catheter of an external pacemaker may be threaded through a vein to the heart in cases of ventricular standstill or complete heart block. The major antiarrhythmic drugs are lidocaine hydrochloride, and a combination of disopyramide phosphate, procainamide hydrochloride, and quinidine. The antiadrenergic blocking agent propranolol hydrochloride may be used in treating arrhythmias. Isoproterenol hydrochloride is indicated for complete heart block and ventricular arrhythmias requiring an increased force of cardiac contractions to establish a normal rhythm. Atropine may be used in the treatment of bradycardia, a sedative in the treatment of tachycardia, and digitalis in the treatment of atrial fibrillation. Calcium channel blockers control arrhythmias by inhibiting calcium ion influx across the plasma membrane of cardiac muscle, thus slowing atrioventricular conduction and prolonging the effective refractory period within the AV node.

The antidysrhythmic effect on adrenaline-induced arrhythmia is also suggestive of [beta]-adrenergic antagonistic effect.
The present results suggested that the beneficial antidysrhythmic efffect of the triterpenoids on ischemia-induced arrhythmia could be attributed to either [beta]-blocker activity or inhibition of [Na.
The beneficial antidysrhythmic effect of the triterpenoids in this type of arrhythmia can be attributed to [beta]-blocking activity and recently reported antioxidant activity (Somova et al.
