Let’s take a look at the signs of tachycardia, symptoms, and tachycardia. Tachycardia (頻 頻 頻) means that the heart rate is over 100 times per minute. Normal heartbeats start from the upper ventricles and deliver signals to the lower ventricles, but the tachycardia is caused by the breakdown of the heart’s normal signaling system due to electrical abnormalities of the ventricles. Tachycardia can be caused by several causes and can cause various symptoms.
Tachy
Tachycardia (頻 頻 頻) means an electrical abnormalities in the ventricles, which means that the heart is pathological. In general, the normal range of heart rate is defined from 60 (or 50) sashimi per minute to 100 times per minute. In the case of normal heart rate, the heart begins with the upper ventricles (the upper part of the heart rate) and transmits the signal to the lower ventricles (lower part of the heart rate), and the heart of the tachycardia is excessive in the lower ventricles, which leads to a fast and irregular heart rate. It is normal for the pulse to rise to more than 100 times when you are excited or excited or nervous, but if you show tachycardia even when stabilizing, you need to find out the exact diagnosis and cause.
Types of tachycardia
Tachycardia is divided into many types, depending on the location and cause of the occurrence.
- Sexual Similarity Bash (PSVT): Tachycardia occurs in the upper part of the heart (atrial or atrial nodules), and there is a feature that starts and ends suddenly. This type of tachycardia usually runs very quickly with 150-250 heart rate per minute, and can often stop through the American neurological stimuli. Mostly, it occurs structurally in a normal heart.
- Ventricular tachycardia: Sashimi that occurs in the lower part of the heart (ventricles), a serious arrhythmia that can threaten life. If the ventricular tach is lasting for more than 30 seconds, immediate treatment is required. In particular, if the blood pressure is too low and has symptoms, immediate heart rate transition (electric shock) may be required.
Diagnostic criteria of tachycardia
The diagnostic criteria of the tachycardia depend on the age.
- adult: Diagnose with tachycardia when the heart rate is over 100 times per minute. In general, the normal heart rate of adults is between 60-100 times per minute.
- Childhood: Children apply different standards by age because their heart rate is faster than adults. For example, children aged 1-2 years old are considered tachycardia when they are 151 times per minute and 8-11 years old.
The difference between tachycardia and bradycardia
Tachycardia and bradycardia are in opposite state representing the abnormalities of heart rate.
- Occurrence: Bash is caused by abnormal activity in the lower ventricles, and the bradycardia is caused by abnormal activities in the upper ventricles. These differences affect the treatment and the prognosis.
- Park Dong -soo: Tachycardia has more than 100 high -speed rhythms per minute, and the bradycardia has a slow rate of less than 60 times per minute. Both state can affect the ability to pump blood efficiently.
Clinical
Tachycardia goes beyond simple symptoms and has an important clinical meaning.
- Lowing heart function: Continuous tachycardia reduces the efficiency of the heart. If your heart jumps too quickly, your heart rate can be reduced due to lack of time to fill your ventricles. This lacks blood supply to the whole body, which may cause a variety of symptoms.
- Indicator of heart disease: Tachycardia can often be an important indicator of the presence of base heart disease. In particular, continuous tachycardia can suggest serious heart problems such as myocardial infarction, myocardialitis, cardiomyitis, and heart valve disease.
Tachycardia is not just an increase in heart rate, but an important symptom of abnormalities in the electrical signal system of the heart. Continuous tachycardia can reduce the efficiency of the heart and cause serious complications, so if you have symptoms of tachycardia, accurate causes and appropriate treatment are required. Especially in patients with underlying heart disease, it is necessary to be more careful because tachycardia may develop into a serious arrhythmia that can threaten life.
Tachycardia
Tachycardia (頻 頻 頻) means that the heart rate is over 100 times per minute. Tachycardia occurs when an electrical abnormalities occur in the ventricles, causing the heart to jump pathologically quickly, and the normal signaling system of the heart is broken. In the case of normal heart rate, the heart begins in the upper ventricles and transmits signals to the lower ventricles, and the heart of the tachycardia is excessive in the lower ventricle, which causes fast and irregular heart rate. Tachycardia can cause a variety of symptoms, and the seriousness of the symptoms depends on the type of tachycardia, duration, and the underlying heart of the patient.
The most common tachycardia
The most common symptoms of tachycardia.
- Shimgye Hangjin (heart pounding): The most common symptom of tachycardia is that the heart beats and irregularly beats. This suddenly occurs and can last a few hours in a minute, and patients complain of thumping. Especially in the case of a seizure sincerity tachycardia, it starts suddenly and suddenly stops.
- Shonity and shortness of breath: Because of the tachycardia, the heart does not pump the blood efficiently, so you can feel short of breath and shortness of breath. It may be especially worse during exercise or activity, and in severe cases, it can occur during rest. This is a symptom caused by the lack of proper blood to the lungs.
Symptoms of hemophilia
When the tachycardes get worse, the pump function of the heart decreases, resulting in various symptoms.
- Dizziness and fainting: Low blood pressure and lack of blood supply to the brain, which can lead to dizziness or fainting. Especially if the tachycardia is severe or lasts for a long time, these symptoms are more prominent. Sudden fainting can lead to dangerous situations, so you need to get medical help immediately.
- Discality and systemic helplessness: If the heart does not supply blood efficiently, the whole body lacks oxygen and nutrients. This makes it difficult for daily activities and increasing fatigue. Especially in patients with heart disease, these symptoms can be more serious.
Heart -related symptoms
Tachycardia has a direct impact on the heart, causing various heart -related symptoms.
- Chest discomfort and pain: Patients with tachycardia may feel uncomfortable with pressure, tightening, and pain in the chest area. This is due to an increase in the amount of oxygen demand in the heart muscles, but the supply is not followed. Especially in patients with underlying heart disease, pain similar to angina can occur.
- Hypotension: Continuous tachycardia can lead to a decrease in blood pressure by reducing the ability to fill and pump the blood appropriately. In severe cases, it can be shocked, which is an emergency that threatens life. Low blood pressure symptoms include pale skin, cold sweat, and reduced consciousness.
Unusual symptoms by age
Synacia symptoms can appear differently depending on age.
- Symptoms of children and infants: Infants and young children may have shock symptoms such as restless or reduction in intake, decrease in intake, and reducing urine. They do not express their symptoms correctly, so they need closely observations of parents or guardians. Continuous tachycardia can lead to heart failure.
- Symptoms of adolescents and adults: Adolescents and adults can more clearly appeal to symptoms such as pounding, pale, loss, chest pain, abdominal pain, and fainting. Especially in the case of ventricular tachycardia, there is a risk of sudden death in patients with heart disease.
If you have symptoms of tachycardia, especially if you have a heart disease or if your symptoms are serious, it is important to immediately seek medical help. Depending on the cause and type of tachycardia, most of the symptoms can improve and normal life. Regular heart checkups and healthy lifestyle maintenance will help prevent and manage tachycardia.
Tachycardia
Normal heartbeats start from the upper ventricles and deliver signals to the lower ventricles, but the tachycardia is caused by the breakdown of the heart’s normal signaling system due to electrical abnormalities of the ventricles. Tachycardia can be caused by many causes, may be temporary symptoms or signs of serious heart disease. Knowing exactly the cause of the tachycardia plays an important role in determining the appropriate treatment method.
Causes of heart disease
The problem of the heart itself can lead to tachycardia.
- Structural heart disease: Synacactor can occur if structural cardiac failure such as myocardial infarction, myocardialitis, cardiomyitis, and heart valve disease can occur. These diseases interfere with the electrical signal system of the heart, causing abnormal heart rhythm. In particular, coronary arteries and heart failure are one of the most common causes of tachycardia.
- Congenital electrical paths or more: Congenital heart disease, such as long Qt syndrome or Surgada syndrome, increases the risk of ventricular tachycardia and other arrhythmia. Such a disease has an abnormalities in the electrical circuit of the heart, which can cause sudden tachycardia when exercising or stressed. In addition, if there is a bypass track, the electrical signal may be delivered through another path in addition to the normal electrical signal path, resulting in tachycardia.
Causes of endocrine and metabolic
Hormonal imbalances and metabolism can cause tachycardia.
- Thyroid: Excessive secretion of thyroid hormones increases heart rate. Thyroid hormones stimulate the heart’s beta receptor to increase the heart rate. Patients with hyperthyroidism can last when stabilized, and other symptoms may be accompanied by weight loss, heat intolerance, and anxiety.
- Electrolyte imbalance: If there is an electrolyte imbalance such as hypokalemia, hymagnesiumemia, etc., tachycardia may occur. Electrolyte plays an important role in the electrical activity of the heart, so this imbalance can affect the heart rhythm. In particular, changes in potassium levels have a great influence on the heart rhythm.
Causes of drugs and materials
Various drugs and substances can cause tachycardia.
- irritant: Everyday stimulants, such as caffeine, nicotine, and alcohol, can increase heart rate. In particular, excessive alcohol intake can cause a temporary atrial fibrillation called ‘Holiday Heart Syndrome’, which is one of the common causes of tachycardia in Korea. In addition, illegal drugs such as cocaine and amphetamine can cause serious tachycardia.
- Drug: Some prescription drugs and nonchest drugs can cause tachycardia due to side effects. This includes tricular antidepressants, antihistamines included in cold medicine, and some antibiotics. Pharmacopathy can also cause tachycardia.
Physical and environmental factors
Everyday situations and environmental factors can also cause tachycardia.
- Stress and anxietyEmotional stress, anxiety, and fear activate the sympathetic nervous system to increase the heart rate. In this situation, adrenaline is secreted and the heartbeat is faster. In most cases, the heart rate is returned to normal when the stress factor is removed.
- Anemia and dehydrationAnemia reduces oxygen transportation in the blood, making the heart jump faster. In dehydration, the amount of blood is reduced, and the heart is beaten faster, so that the body needs to supply the blood necessary for the body. This condition is corrected with appropriate treatment.
The causes of tachycardia are very diverse, so if you have persistent tachycardia symptoms, it is important to get a doctor’s care to identify the exact cause. The treatment varies depending on the cause, and the proper treatment allows most of the tachycardia to be effectively managed. Especially in patients with heart disease, tachycardia can have more serious consequences, so regular heart checkups are required.
FAQ
Q: What is the exact meaning of the tachycardia?
A: Tachycardia means an abnormally fast state with more than 100 heart rate per minute. In the case of normal heart rate, the heart starts from the upper ventricles and delivers signals to the lower ventricle, and the heart of the tachycardia is excessive in the lower ventricle, which causes fast and irregular heart rate. Tachycardia is divided into seizure sincerity and ventricular tachycardia, depending on the occurrence.
Q: What are the main symptoms of tachycardia?
A: The most common symptom of the tachycardia is the heart -tight pear (heart pounding), which can feel the heart beating and irregularly beaten. In addition, symptoms such as shortness of breath and shortness of breath, dizziness and fainting, weakness and systemic helplessness, chest discomfort and pain, and hypotension may occur. The seriousness of the symptoms depends on the type of tachycardia, duration, and the baseline heart of the patient.
Q: What is the main cause of the tachycardia?
A: The cause of the tachycardia can be divided into the causes of heart disease, the cause of endocrine and metabolic, the cause of drugs and materials, and physiological and environmental factors. Structural cardiac disorders such as myocardial infarction, myocardial disease, cardiac valve disease, thyroid dysfunction, electrolyte imbalances, stimulants such as caffeine, nicotine, alcohol, stress and anxiety, anemia and dehydration can cause tachycardia.
Q: How do I treat tachycardia?
A: The treatment of tachycardia varies depending on the cause and the seriousness of the symptoms. Mild tachycardia can be improved by removing the cause (reducing caffeine intake, stress management, etc.). For drug therapy, beta blockers, calcium passage blockers, and anti -arcent agents are used. If it does not respond to serious tachycardia or medication, procedures such as high frequency electrode pottery, heart rhythm switching (electric shock), and heart rate tuning insertion may be required.
