Many arrhythmias require no treatment. For serious arrhythmias, treatment of underlying heart disease sometimes controls the arrhythmia. In some cases, the arrhythmia itself with drugs, electric shock (cardioversion) and implantable cardioverter-defibrillators, artificial pacemakers, catheter ablation, or surgery may be treated. Supraventricular arrhythmias can often be treated with medication. Ventricular arrhythmias are more complex to treat. Drug therapy can manage many arrhythmias, but finding the right medication and dosage requires care and may take some time. Common drugs for suppressing arrhythmias include beta blockers, calcium channel blockers, quinidine, digitalis preparations and pro-cainamide. Because of potential serious side effects are stronger medication only desensitization are used to treat life-threatening arrhythmias. All medications for the treatment of cardiac arrhythmias have possible side effects ranging from minor complications with beta-blockers and calcium antagonists to serious consequences of drug desensitization may paradoxically cause or exacerbate arrhythmias. Response to drugs is usually measured by ECG, Holter or electrophysiologic study. In an emergency cardioversion or defibrillation (the use of electric shock to the chest wall) is used. Cardioversion, the heart back to its normal rhythm. It is followed by a drug treatment to prevent, a recurrence of the arrhythmia. Artificial pacemaker, which transmit electrical signals, is likely to make the heart beat faster are implanted under the skin in one simple operation. Pacemaker leads anchored on the right side of the heart. Pacemakers are used to correct bradycardia and are sometimes used after surgical removal or catheter. Automatic implantable defibrillators correct lethal ventricular arrhythmias by recognizing and then again a normal heart rhythm by stimulation of the heart or give an electrical shock. They are implanted in the chest wall without major surgery and store information for future evaluation by physicians. Automatic implantable defibrillators were more effective in saving lives than drugs alone. They are often used in conjunction with medication. Ablation, a procedure to amend or remove the heart tissue causing the arrhythmia in order to prevent a repetition can be performed through a catheter or surgery. Supraventricular tachycardia can be successfully treated by ablation. Catheter ablation is performed in a catheterization laboratory with the patient sedated. A catheter with a device that has the heart of the electric railways card inserted in a vein and is in the radio-frequency heart.High threads are then used to remove track (s) causing the arrhythmia. Surgical removal is similar in principle, but it is performed in a hospital with a cold probe to destroy the radio waves to tissue. Ablation treatments are used when medications fail. Maze surgery treats atrial fibrillation by multiple incisions through the atrium, so that electrical impulses to move effectively. This is common in patients who did not respond to medication and cardioversion is recommended. For some arrhythmias can be fatal, a doctor should always be consulted traditional medicine first. Acupuncture may correct an insignificant number (1.5%) cases of atrial fibrillation. For new, minor arrhythmias, acupuncture may be effective in 70% of cases, but that may not fall significantly from the placebo treatment. Both Western and Chi-nese medicines are also used in the treatment of cardiac arrhythmias. Since hawthorn (Crataegus laevigata) dilates blood vessels and stimulates the heart muscle, it can lead to a stabilization of the arrhythmia. He is gentle and suitable for home use, as opposed to digitalis (Digitalis purpurea), an herb whose action on the heart is too powerful to use without supervision by a qualified doctor. Homeopaths may prescribe remedies such as Lachesis and monkshood or aconite (Aconitum napellus) to treat mild heart rhythm disturbances.
