Treatment of cardiac arrhythmia

If you have been diagnosed with arrhythmia (heart rhythm disorder), treatment may sometimes be necessary, often not. Generally, treatment is only needed if the arrhythmia provided clear distress, or if it entails the risk that you will get a more serious arrhythmia, or a complication of arrhythmia.

Vagus Manovre
You can stop a supraventricular tachycardia by performing certain maneuvers, such as holding your breath, tightening in the abdomen as if you're sitting on the toilet, sprinkle cold water on the face or cough. There are other maneuvers that can stop a rapid pulse. These maneuvers affect the nervous system that controls heart rate (vagus nerve), and often have the heart to calm down.

There are various drugs that stop or damping down an arrhythmia (antiarrhythmics). The choice of product depends on whether it is an emergency, long-term treatment or a complication of an arrhythmia. Most antiarrhythmic drugs work by reducing heart rate in one of two ways. One way is to suppress the activity of the pacemaker tissue that triggers the too rapid impulses. The other way delays the transmission of fast impulses within the heart.

Antiarrhythmics can have serious side effects. Sometimes it actually enhances the antiarrhythmic preparation occurrence of the arrhythmia that was supposed to treat, or endotin may cause new arrhythmias that can be as bad or worse than it was to be treated. Adverse events not related to the heart, may also occur.

basis and treatment of cardiac arrhythmias

Electric shock
If you have atrial tachycardia, for example. Atrial fibrillation, your doctor may use drugs or an electric shock to your heart to get back to its regular rhythm. In some cases, be given blood-thinning medicines before the shock treatment to prevent the formation of blodlevrer in your heart.

Shock treatment is given under light anesthesia via electrodes on the chest. The shock causes the heart to stop for a second. When it turns on, it will often resume a normal rhythm. Electrical shock can sometimes cause your heart regains its normal rhythm on a permanent basis, but more often needed antiarrhythmic drugs to maintain the normal rhythm for a long time. However, atrial fibrillation that has been yearned to react badly to such treatment.

It is possible to get your heart rate to beat through with drugs. Treatment requires hospitalization so that you can observe a few hours. If treatment is successful, the same or a similar drug used as maintenance therapy.

Catheter ablation
By this procedure carried one or more catheters through arteries and into the interior of the heart. They are placed along the electrical conduction pathways that your doctor has found the cause of your arrhythmia. Electrode at the catheter tip is heated with radio waves. This destroys a small spot of heart tissue (ablation) and creates an electrical block in the cable causing your arrhythmia. Typically, this arrhythmia is about to expire. Catheter ablation works best in the treatment of arrhythmias caused by a single abnormal pathway, eg. atrial flutter and Wolff-Parkinson-White syndrome. However, catheter ablation can also be used in the treatment of arrhythmias included many electrical conduction pathways, for example. atrial fibrillation.

Complications are few. It can be heart damage, infection, formation of the blood clot. Moreover, catheter ablation little or no discomfort and can be performed under a light drug and local anesthesia. For this reason, catheter ablation has become an increasingly frequent method of treatment used.

If you have an annoying slow pulse (bradycardia), which does not have a cause that can be correct - e.g. hypothyroidism or side effect of a medicine - the treatment is often a pacemaker. A pacemaker is a small battery-powered device the size of a matchbox that is usually implanted under the skin just below the collarbone. One or more electrode is from the pacemaker through blood vessels to the interior of the right side of your heart. If your heart rate is too slow or if the heart stops, the pacemaker detects it and sends out electrical impulses that get your heart to beat with a steady, appropriate rate. When the pulse is over a certain level, connect the pacemaker itself. The pacemaker can be programmed so that it is "tailored" for your needs.

Implantable defibrillators
This device can be implanted if you are at high risk of developing a dangerous ventricular tachycardia or ventricular fibrillation. Defibrillator is battery operated and implanted just under the left collarbone. One or more wires of an electrode at the tip go through the veins to the heart. Defibrillator constantly monitors your heart rhythm. If it detects that the rhythm is too slow, it can stimulate the heart as a pacemaker can. If it detects ventricular tachycardia or ventricular fibrillation, it sends out low-or high-energy shocks that re-sets the heart to the normal rhythm. Compared with drugs seems defibrillator to reduce the risk of fatal arrhythmias with approx. 50%.

Maze procedure. This procedure involves making a series of surgical incisions in the atria. These heal with scars that break the wiring harness so that the flow of electrical impulses spread out in an orderly manner from top to bottom. The procedure has 80-95% success rate, but because it requires open-heart surgery, reserve it for people not being helped by other treatments. Newer techniques include the use of frys proper or hand-held radio wave probes, rather than a scalpel, to create these lines with scars.

Ventricular aneurysm surgery. If catheter ablation and implantation of a defibrillator do not work, surgery may be necessary. It may mean to remove any ballooning of the heart (aneurysm) that may be responsible for the arrhythmia. By removing the source of the abnormal impulses can eliminate the arrhythmia.

Coronary bypass surgery. If you have severe coronary artery disease in addition to frequent ventricular tachycardia, coronary artery bypass surgery may be appropriate. It can improve blood supply to the heart and reduce the propensity to ventricular tachycardia.
