Back Cardiac arrhythmias


The Clínica's Arrhythmia Unit is one of the most experienced units in the treatment of this type of disease.

Occasionally, arrhythmias are completely benign and do not require treatment. However, most of the time, arrhythmias require treatment. To this end, there are specific drugs known as antiarrhythmic agents.

The Arrhythmia Unit has also been a pioneer in a number of the techniques described below:

Radiofrequency ablation resolves more than 90% of some types of arrhythmia.

Some types of arrhythmia, such as paroxysmal tachycardia and atrial flutter, are fully cured with radiofrequency ablation, a breakthrough in the treatment of arrhythmias, which cures more than 90% of arrhythmias. The arrhythmias reappear in less than 5% of patients.

After an electrophysiological study, which consists of the insertion of an electrocatheter into the cardiac cavities, the focus of the myocardial tissue that causes the arrhythmia is destroyed. The procedure is very safe, relatively simple and fast. It fully eliminates a considerable number of arrhythmias that would otherwise be difficult to solve or that would require lifelong treatment with drugs.

The procedure is performed through the puncture of a vein in the groin. The patient is administered local anaesthesia and can be discharged in a few hours.

This is a combined procedure that is performed on patients with atrial fibrillation and who have problems with Sintrom® or other anticoagulants.

The procedure consists of inserting (using a catheter and without the need for open surgery) a device that closes a cavity adjacent to the left atrium of the heart, known as the atrial appendage, where thrombi commonly originate. This cardiac cavity has the anatomical shape of a small sack (similar to the appendix) in which a certain quantity of blood pools on its way through the left atrium, which favours the formation of blood clots.

By closing the outlet of the atrial appendage through the placement of the new device, the migration of the thrombi generated inside the atrial appendage through the cardiovascular system is impeded. This procedure thus prevents the risk of clots from the atrial appendage reaching the brain and causing a stroke[SP], among other potential and severe complications. In fact, 90% of thrombi are known to originate in this left atrial appendage.

Cryoablation: The use of cold for treating arrhythmias faster.

Cryoablation is an advanced technique for treating nonpersistent (paroxysmal) atrial fibrillation. The greatest benefit of this technique is that the treatment is performed by freezing, in a single, quick and effective energy pulse.

The procedure has already been conducted successfully on the first patients. To date, the conventional method has applied point-by-point radiofrequency pulses over the entire circumference of the pulmonary veins, where the arrhythmias occur.

El Dr. García Bolao explica en qué consiste la fibrilación auricular, su tratamiento y curación mediante la crioablación.

The application of cold is achieved by inserting a balloon filled with nitrous oxide (a chemical compound used as the source of cold) through a catheter, which reaches the intersection of the pulmonary veins with the left atrium to thereby isolate and prevent the propagation of the abnormal electrical impulse.

Pacemakers are small electronic devices that help the heart.

Pacemakers are small electronic devices that can analyse the heart rhythm and treat arrhythmias using electrical stimuli. Its purpose is to supplement the functions of the cardiac conduction and excitation system. The device is generally implanted under local anaesthesia throughout almost all of the procedure.

Recovery from the intervention is fast, and patients can be discharged from the hospital in two to three days. When the batteries run out (approximately every six years), the pacemaker needs to be replaced.

The Clínica can remotely control the pacemakers through a system that sends technical information on the devices from the patients’ homes on a daily basis. Improved control over the disease is thereby achieved. The programme monitors the operation of the implanted devices and transmits the technical data to cardiologists by mobile telephone on a daily basis.

Patients with severe and potentially lethal arrhythmias might need to have an automatic defibrillator implanted. The device restores the patients’ normal cardiac rhythm by automatically applying electrical currents.

The defibrillator permanently controls the heart rhythm. When an arrhythmia is detected, the device uses various treatments using electrical impulses to suppress the arrhythmia.

Depending on the severity of the arrhythmia, the defibrillator automatically applies softer (antitachycardia stimulation) or more radical (cardioversion through electrical shock) treatments, which can occasionally be perceived by the patient.

The subcutaneous defibrillator can treat serious cardiac arrhythmias without direct access to the heart. [Video only available in Spanish]

Sometimes the defibrillator is combined with cardiac resynchronisation therapy, thereby improving the heart failure that the patient can occasionally experience.

The Clínica can remotely control the defibrillators through a system that sends technical information on the devices from the patients’ homes on a daily basis.
