What's the treatment for cardiac arrhythmia?

The pharmacological treatments consist of agents that interfere with sodium, pottasium, and calcium pump systems, which are used by the heart to control heart rate. These agents tend to result in longer times between each impulse, by prolonging repolarisation (the heart cells pump Na+ across their membranes during a contraction, and then pump Na+ back in ready for another contraction, this is called repolarisation). Another important class is the Beta blockers, which block the action of

adrenaline (a naturally produced hormone, which increases heart rate). Antiarrhythmic medications help to change the electrical signals within the heart to suppress or prevent the arrhythmia. These medications can be used to control SVT (supraventricular tachycardia) and VT (ventricular tachycardia). It is important to be aware that medications are a treatment and not a cure. Your doctor will discuss the advantages and disadvantages of antiarrhythmic therapy. Frequently medication is prescribed in addition to other therapies such as ICD or pacemaker.

Arrhythmias are also treated electrically. Cardioversion is the application of electrical current across the chest wall to the heart and it is used for treatment of supraventricular or ventricular tachycardia. Defibrillation differs in that it is used for ventricular fibrillation and more electricity is delivered with defibrillation than with cardioversion. In cardioversion, the recipient is usually awake and may be sedated for the procedure. In defibrillation, the recipient has lost consciousness so there is no need for sedation. Electrical treatment of arrhythmia includes cardiac pacing. Pacing is usually done for very slow heartbeats from drug overdose or myocardial infarction.

More information on cardiac arrhythmia

What is cardiac arrhythmia? - Cardiac arrhythmia is a disturbance of the heart rhythm. Cardiac arrhythmias can range in severity from entirely benign to immediately life-threatening.
What types of cardiac arrhythmias are there? - Types of cardiac arrhythmias include supraventricular tachycardia, Wolff-Parkinson-White syndrome, atrial fibrillation, ventricular fibrillation, bradycardia.
What causes cardiac arrhythmias? - Cardiac Arrhythmias occur when the heart beats improperly, as a result of incorrect impulse generation, or impulse conduction.
What're the symptoms of cardiac arrhythmia? - The signs and symptoms of cardiac arrhythmias can range from completely asymptomatic to loss of consciousness or sudden cardiac death.
How is cardiac arrhythmia diagnosed? - Cardiac arrhythmias are often first detected by simple but nonspecific means. One diagnostic test for assessment of heart rhythm is the electrocardiogram.
What're the treatments for cardiac arrhythmia? - The pharmacological treatments for cardiac arrhythmia consist of agents that interfere with sodium, pottasium, and calcium pump systems.
