The heart of the clock, device, medications can help to obtain rate and rhythm. In addition, a non-drug Alternative is gaining in importance, the so-called catheter ablation, is reported by Priv.-Doz. Dr. René Andrié from the heart center, Helios Klinikum Siegburg, Germany, on a training event for pharmacists in Schladming, Austria.
More or less happens to be a cardiologist, have discovered that patients with atrial fibrillation in the pulmonary veins in the left atrium of the heart lead, in certain areas, the electrical excitation in an uncontrolled manner, Andrié. It is a matter of individual muscle cells, the Impulse and so the atrial fibrillation can cause. Goal of catheter ablation is to conduction along the vein wall to interrupt. "This is done by erzeugt" on the venous approach using a catheter, specifically a ring-shaped scar in the tissue;, the physician explained.
This can be done via a catheter, either by using electricity or a cold balloon. "We push the catheter with the balloon in one of these veins, then we fill it with Lachgas", so the cardiologist. During the procedure the doctor can determine by x-ray control whether the balloon is achieved the venous wall with no gaps. Then the cold balloon is cooled to -80 °C. Where he comes up with tissue in contact, the result is then ring-shaped scars around the veins approach. This procedure will be performed in each vein twice, each for four minutes.
"When it comes to the recurrence of atrial fibrillation, this method is more effective than any Medikament", Andrié said. The complication rate was low, and in individuals with cardiac insufficiency, the treatment of sink in addition, even the mortality rate.
Atrial fibrillation the most common sustained heart rhythm disorder. "One can roughly say that every fourth wird" get from 40 in his life atrial fibrillation;, estimated Andrié and stressed how important it was to treat atrial fibrillation, as in the case of Affected the mortality significantly be increased. The same is true for the risk of stroke. The symptoms include a heart rhythm disorder felt can make, the feeling of an irregular heartbeat, heart palpitations or interruptions, feeling unwell, shortness of breath and dizziness to loss of consciousness and sudden cardiac death.
