Tachyarrhythmias
Supraventricular - a group of diseases that occur in the upper chambers of the heart (atria), which include such diseases as atrial fibrillation, atrial flutter, and paroxysmal tachycardia (AVVT, AVVT, including WPW). In rare cases, they pose a direct threat to life.
Symptoms: they are most often manifested by sudden attacks of palpitations, a feeling of the heart not working properly, compression in the chest, neck, with prolonged attacks, symptoms of shortness of breath, swelling of the lower extremities are added. They respond well to both medical and surgical treatment (catheter ablation).
Ventricular diseases are a group of diseases of different etiology that occur in the lower chambers of the heart (left and right ventricles). This group includes: ventricular tachycardia, fibrillation and flutter. Sometimes they occur as a complication of other diseases (ischemic heart disease, myocardial infarction, hypertrophic cardiomyopathy, etc.) and often pose a direct threat to life and health. Sometimes it will be necessary to install a cardioverter-defibrillator, catheter ablation. Idiopathic ventricular tachycardia is a group of benign ventricular rhythm disorders that occur in younger people, they are subject to both medical and surgical treatment.
Bradyarrhythmias
A group of so-called blockades (atrioventricular, sinoatrial) - heart attacks that occur more often in the elderly, or as a complication of other heart pathologies (ischemic disease, valvular pathology, myocarditis). They are often manifested by shortness of breath, sudden dizziness, loss of consciousness, and a decrease in tolerance to physical exertion.
The standard of treatment is the installation of a permanent artificial pacemaker.
What are electrophysiological research and RFA
EFD (electrophysiological study) is a test to evaluate the electrical signals of the heart. It is used to identify the exact cause and localize the place of origin of the arrhythmia.
How the test is conducted:
To perform this test, electrodes are inserted into the heart. These electrodes measure the electrical activity of the heart.
The procedure is performed in the catheterization laboratory of the hospital. The team of medical specialists includes a cardiologist, operators and nurses.
How are these procedures carried out?
Usually, after anesthesia (local anesthetic), a puncture (puncture) of veins in the groin and/or neck is performed. After that, the cardiologist will insert several venous catheters (introducers) into the groin or neck area. Next, special wires or electrodes are inserted through them into your body. The doctor uses moving X-ray images (fluoroscopy) to guide the catheter, introduce it into the heart and place the electrodes in the right places.
Electrodes record electrical signals of the heart. During the procedure, the doctor can provoke the appearance of arrhythmia to confirm or refute the diagnosis. You may also be prescribed medication for the same purpose.
