Arrhythmia is a disease that causes heart rhythm problems due to poor electrical stimulation of the heart or poor transmission of impulses. [사진= 게티이미지뱅크]The weather is going on a ‘roller coaster’, with temperatures dropping sharply in November and then summer temperatures appearing unseasonably. The Korea Meteorological Administration forecast that temperatures will drop again from early next week.
When the weather gets cold, the blood vessels through which blood passes constrict, causing a sudden rise in blood pressure, increasing the burden on heart function. In addition, large daily temperature differences of more than 10 degrees between day and night have a significant impact on the occurrence and worsening of arrhythmia diseases. If the temperature fluctuates, the risk of arrhythmia increases.
The heart beats regularly and continuously, maintaining a certain rhythm using the electrical transmission system within the heart. The normal number of times is usually 60 to 100. Arrhythmia is a disease that causes heart rhythm problems due to poor electrical stimulation of the heart or poor transmission of impulses. Along with irregular pulse, it is often accompanied by symptoms such as dizziness, fatigue, and lack of energy. Symptoms range from mild symptoms such as palpitations to severe symptoms such as fainting or heart attack.
If it beats regularly and slowly, less than 60 beats per minute, it is classified as bradycardia, and if it beats regularly and faster than 100 beats per minute, it is classified as tachycardia. If the pulse beats regularly but suddenly becomes undetectable and weak, it is an arrhythmia called ‘extrasystole’. Bradycardia, tachycardia, and extrasystoles do not cause major problems if they are managed well. Still, it is essential to go to the hospital to receive an accurate diagnosis and receive appropriate treatment.
One of the most common and dangerous arrhythmias is fibrillation (atrial fibrillation), in which the pulse beats irregularly and very quickly. Careful caution is required as it can cause sudden death. Tachycardia that occurs in the atria is called atrial tachycardia, and tachycardia that occurs in the lower ventricle is called ventricular tachycardia. Fibrillation is the most common arrhythmia among atrial tachycardias. The main symptoms include feeling like your heart is pounding very fast, feeling like you are about to collapse, feeling like you are sick, dizziness, cold sweat, and chest pain. It is the number one cause of sudden cardiac death.
Latest treatments such as 3D imaging ‘electrode catheter ablation’ emerge
Arrhythmias are often described as ‘like a goblin’ or ‘having a thousand faces.’ This is because the symptoms of arrhythmia can last for a long time, but in many cases they appear and disappear for a short period of time. In some people, arrhythmia may occur only a few minutes a year. When symptoms appear and go to the hospital, it is common for them to return to normal. There are many cases where something ‘comes like the wind and disappears like dew.’
In addition to congenital abnormalities of the heart, arrhythmia can be caused by cigarettes, alcohol, caffeine, and other heart diseases such as myocardial infarction and high blood pressure. It is a good idea to reduce smoking and drinking, and to regularly engage in aerobic exercise. Start the exercise very lightly and gradually increase the intensity, then gradually lower it towards the end. It is also necessary to regularly measure blood pressure, blood sugar, and cholesterol levels to check for high blood pressure or hyperlipidemia.
If arrhythmias are further subdivided, they are classified into various types according to the mechanism of occurrence, site of occurrence, and pulse rate, such as atrial fibrillation, ventricular fibrillation, ventricular premature beats, atrial premature beats, supraventricular tachycardia, ventricular tachycardia, atrioventricular block, and sinus node dysfunction syndrome. . As the symptoms and types are diverse, various treatments are also applied. They range from mild conditions that can be treated without separate treatment or with simple procedures, to cases that require continuous outpatient follow-up and concurrent drug treatment after insertion of a pacemaker, defibrillator, or ventricular resynchronization therapy device.
Professor Hwang Yu-mi of the Arrhythmia Clinic at St. Vincent Hospital of the Catholic University of Korea explained, “These days, electrode catheter ablation is possible using a 3D mapping system.” When a special electrode catheter is placed inside the heart, the cardiac image is created as a 3D image through the catheter position signal and cardiac electrical signal, allowing the cardiac structure of each patient to be closely checked and the position and movement of the catheter to be identified in real time. It is a treatment that is administered. Because the procedure can be performed while checking the catheter in real time, a safe and accurate procedure is possible.
