परिभाषा

Tachycardia is a rapid heart rate of more than 100 beats per minute. Sinus tachycardia, from the heart’s sinus node, is a normal response to exercise, illness, or stress.

There are several types of abnormal tachycardias or arrhythmias. These can come from two places:

  • Atria (the two smaller chambers on the top of the heart)—called supraventricular tachycardias
  • Ventricles (the lower chambers of the heart)—called ventricular tachycardia

This condition can be life-threatening. But, it can be treated. If you think you or someone you know has this condition, get emergency help.

tachycardia

का कारण बनता है

This condition is caused by abnormal electrical impulses that control the heart.

जोखिम कारक

These factors increase your chance of having tachycardia. Tell your doctor if you have any of the following:

  • Heart disease, especially a prior heart attack
  • Cardiomyopathy —damage to the muscle wall of the lower chambers of the heart
  • Electrolyte abnormalities—too much or too little calcium, sodium, magnesium, and potassium in the blood
  • Myocardial ischemia—insufficient blood flow to heart muscle tissue
  • Hypoxemia—not enough oxygen in the blood
  • Acidosis—too much acid in the body’s fluids

लक्षण

If you have any of these symptoms do not assume it is due to this condition. These लक्षण उत्पन्न हो सकते हैं अन्य शर्तों द्वारा. यदि आपके पास इनमें से कुछ है तो अपने डॉक्टर को बताएं:

  • दिल की घबराहट
  • तेज़ हृदय गति
  • चक्कर आना
  • चक्कर
  • Fainting or near fainting
  • छाती में दर्द
  • सांस लेने में कठिनाई

निदान

  • Your doctor will ask about your symptoms and medical history. You will also have an exam. Tests may include the following:
    • Electrocardiogram (ECG, EKG) —a test that records the heart’s activity by measuring electrical currents through the heart muscle
    • Holter monitor or event monitor —an ambulatory monitor to record your heart rhythm that can be worn from 1-30 days to detect arrhythmias and correlate symptoms with the heart rhythm
    • Exercise test —particularly if the symptoms occur during physical activity
    • Electrophysiology study —an invasive test where monitoring wires are placed inside the heart and the heart’s conduction system is tested directly
    • Cardiac catheterization —a tube-like instrument inserted into the heart through a vein or artery (usually in the arm or leg) to detect problems with the heart and its blood supply

उपचार

अपने चिकित्सक के साथ बात के बारे में सबसे अच्छा उपचार योजना के लिए आप. उपचार के विकल्प में निम्न शामिल हैं:

दवाएं

The following medications are used to treat this condition:

  • Beta-blockers (eg, atenolol, metoprolol, bisoprolol)
  • Calcium channel blockers (eg, diltiazem, verapamil)
  • Anti-arrhythmics, such as flecainide (Ambocor), procainamide (Procanbid), amiodarone (Cordarone), and sotalol (Betapace)

पृथक करना

Ablation is done during an electrophysiology study. Radiofrequency energy or cold energy is used to destroy the abnormality and possibly cure the problem.

Cardioverison

An electric shock is applied to the heart to stop the abnormal rhythm. This treatment may be done for life-threatening rhythms, such as ventricular tachycardia orventricular fibrillation. It is also done for milder arrhythmias, such as atrial fibrillation.

Implantable Cardioverter Defibrillator (ICD)

An ICD can be surgically placed into your body. This device monitors your heartbeat. It can apply a shock to correct an irregular heartbeat.

रोकथाम

Reducing risk of heart disease is the best way you can prevent this condition. Take the following steps:

  • Maintain a healthy weight
  • Begin a safe exercise program with the advice of your doctor
  • If you smoke, quit
  • Eat a healthful diet, one that is low in saturated fat and rich in whole grains, fruits, and vegetables
  • Manage stress
  • Avoid or limit the intake of caffeine and alcohol
  • Have regular physical exams
  • Treat underlying medical problems (eg, high blood pressure, cholesterol problems)
