Long QT Syndrome (LQTS) is a disorder that affects the normal electrical activity of the heart (heart rate). Sudden death and dangerous and uncontrollable cardiac arrhythmias are among the most serious consequences. Cardiac Arrhythmia is a disorder that disrupts the normal, healthy rhythm of the heartbeat. In this article, you will read more about Cuit Syndrome. We will also talk about the symptoms and side effects of this rare and dangerous disease, what can be done to treat it, what factors increase the risk of developing it, and other such information. Stay with us.
What is Cuit Syndrome?
Using the electrocardiogram device, the electrical activity of the heart can be seen in the display of the device in the form of waves and diagrams. What we call an ECG. Each heartbeat, which is actually an electric current and wave, is indicated by an English letter in the ECG that appears on the device display: P, Q, R, S, and T waves.
The term “QT interval” is used to refer to the electric current between the two waves Q (Q) and T (T). The cut-off distance is normally one-third the size of the distance between the other waves on the ECG. For someone with long QT syndrome, the QT distance will be longer than usual. When this happens, there is a possibility that the normal rhythm of the heartbeat will be disrupted, which is dangerous and serious.
Signs and symptoms of QT syndrome
In some cases, the patient has no signs or symptoms of long-term CVD. In such cases, the disease is called “silent QQ syndrome”. In these cases, they usually find out about the disease by chance and with the help of one of the following:
- Giving genetic testing for other issues;
- ECG examination for disease or other disorder;
- Get tested for a family history of QT syndrome.
Syncope is the most common symptom of long Q syndrome. When the normal heartbeat is disturbed, it is possible to faint. Arousal of emotions such as anger or panic, and excitement will increase the likelihood of syncope for the susceptible person (as well as strenuous physical activity and exercise).
Some people experience signs and symptoms such as lightheadedness, palpitations, fatigue, or blurred vision before fainting. For some, it has no symptoms and happens suddenly. Seizures are another symptom that some patients with long-term CVD may experience.
In most cases, after the onset of these symptoms, the heartbeat returns to normal and normal. If this does not happen spontaneously or if the electric shock device is not used in time to restore the heart rhythm to normal, there is a possibility of sudden death of the patient.
Causes of prolonged Qut syndrome
As you know, one of the main functions of the heart is to pump blood through the arteries and deliver it to other organs in the body. Each heartbeat generates an electrical wave that allows blood to be pumped. There are short breaks in which the heart charges and prepares for the next beat. For a patient with Q syndrome, these time intervals (the distance between the Q and T waves) are longer. This is the main cause of disturbed normal heart rhythm and symptoms such as fainting, seizures and even sudden death.
1. Genetic factors
Hereditary and genetic issues are the main cause of Cuit syndrome; That is, the mutated genes that cause the disease pass from the father, mother, or both to the fetus. Long-term cue syndrome is inherited in two ways: either the mutated gene enters the fetus only from one parent, or two mutated genes from both parents. The second type is rarer and more dangerous.
2. Taking some medications
There are more than 100 different drugs that can extend the time interval between two electric waves Q and T. These drugs can disrupt the normal rhythm of the heartbeat in people who have no problems with heart health and lead to prolonged Q syndrome. Below, you can read the names of some of these drugs:
- Some types of antiemetic drugs;
- Some types of antidepressants and antipsychotics;
- Cholesterol-lowering drugs and some types of diabetes medications;
- Some types of antifungal pills that are effective in treating yeast infections;
- Drugs for regulating heart rhythm (especially drugs for improving the symptoms of cardiac arrhythmia);
- Common antibiotics such as erythromycin and azithromycin.
3. Other Possible Causes of Long Non-Genetic QT Syndrome
The following are other possible causes of this syndrome:
- Covid virus 19 (coronavirus);
- Calcium deficiency (hypocalcemia);
- Magnesium deficiency (hypomagnesemia);
- Potassium deficiency in the body (Hypokalemia).
Diseases and disorders that cause a lack of these nutrients in the body may be the cause of long-term Q syndrome; For example, diarrhea and vomiting in the long run may cause this. Some eating disorders, such as anorexia nervosa and some thyroid-related disorders, may lower blood potassium levels and lead to Q syndrome.
What factors increase the risk of developing Q syndrome?
The following are some of the risk factors associated with this syndrome and will increase the risk of developing it:
- Severe diarrhea and vomiting;
- Having a history of cardiac arrest;
- Degree of relatives close to long QQ syndrome;
- Regular use of pills that cause the syndrome;
- Eating disorders such as anorexia nervosa that upset the body’s electrolyte balance.
When is it necessary to see a doctor?
If you suddenly faint due to strenuous physical activity or emotional arousal or taking new medication, you should see a specialist and find out the cause. If one of your close relatives (spouse, father, mother, sibling) has a history of Cuit syndrome, you should also see a specialist for testing. We have said before that this syndrome may be rooted in genetic issues, and when a family member has the disease, others should be tested.
Treatment of prolonged Qut syndrome
The treatment used for QQ syndrome will vary depending on some factors, such as the type of syndrome, the symptoms, and the medications the patient is taking. In general, one or more of the following strategies are used to treat this syndrome:
- Lifestyle changes: People with Qut syndrome should first of all consider some lifestyle issues; For example, they should not participate in strenuous exercise and physical activity, and should try to be less stressful and emotional in situations. The stress and excitement of doing so may exacerbate the symptoms of Cuit syndrome. There are also positive lifestyle changes that a patient with this syndrome can consider; Changes such as eating more potassium-rich foods in the diet should, of course, be done in consultation with a specialist.
- Drug treatment: Beta-blockers (beta-blockers) are drugs that prevent the heart from beating faster in response to stress and excitement. These drugs are prescribed for the majority of patients with prolonged Qut syndrome. Sodium channel blockers such as megillitin are also effective in controlling the symptoms of the syndrome.
- Insert the device in the heart: Sometimes it is necessary to insert devices such as pacemakers in the patient’s heart to return the heart rhythm to normal and prevent heart arrhythmias. These devices will help maintain a normal heart rhythm with the controlled electric current they generate. Of course, someone who has such a device implanted in their body should see a specialist on a regular basis. In addition, make sure the device is working properly and other safety tips.
- Surgery: If the specialist feels that there is a risk of sudden death following prolonged Qut syndrome, he or she may refer the patient to a surgeon. In surgery, the nerves that disrupt the normal rhythm of the heartbeat are disabled.
in the end
Long-term CVD syndrome is a rare and relatively dangerous disease. If you do get it, you usually have to be careful for the rest of your life. People with this syndrome should take the risk of symptoms seriously. They should try to expose themselves to less stressful situations. Any additional stress and excitement may cause symptoms of the syndrome, including fainting or cardiac arrhythmias, both of which are dangerous.
Long-term CVD syndrome can be prevented if it is genetic, that is, if it has spread from parent to child. However, another type of syndrome that has an external cause and factor can be prevented and by recognizing these factors, its occurrence can be prevented; For example, taking certain medications may lead to Q syndrome, as well as certain types of illness and a lack of nutrients such as potassium and calcium in the body.
