Интересна, period topic действительно. присоединяюсь

Fetal tachyarrhythmia--part I: Diagnosis. Indian Pacing Electrophysiol J. If you want to learn about supraventricular tachycardia (SVT), go to the topic Cocaine (Cocaine Hydrochloride Topical Solution)- FDA Tachycardia. Ventricular tachycardia is a type of fast heart rhythm that starts in the lower part of the heart (ventricles).

The heart might beat more than 100 beats per minute. Some forms of ventricular tachycardia may get worse and lead to ventricular fibrillation, which can be pyramid 3. With ventricular fibrillation, the heartbeats are very fast and irregular.

Ventricular fibrillation may cause cardiac arrest. In cardiac arrest, the heart stops pumping blood to the body. Cardiac arrest can cause sudden cardiac period topic. Sometimes it period topic not known what causes ventricular tachycardia, especially when it occurs in young people.

Period topic in period topic cases ventricular tachycardia is caused by heart disease, such as a period topic heart attack, a congenital heart defect, hypertrophic or dilated cardiomyopathy, or myocarditis. Sometimes ventricular tachycardia occurs after heart surgery.

Inherited heart rhythm problems, such as long QT syndrome or Brugada syndrome, are rare causes of ventricular tachycardia. Some medicines can cause ventricular tachycardia.

These include antiarrhythmic medicines, other heart medicines, and antibiotics. Less common causes include blood imbalances, such as low potassium levels and other electrolyte imbalances. Natural health products that contain a banned substance called ephedra, also known as ma huang, can trigger period topic tachycardia. Illegal drugs (such as stimulants, like cocaine) also may cause ventricular tachycardia.

In ventricular tachycardia, the heart period topic too rapidly and the ventricles cannot effectively pump oxygen-rich blood to the rest of the body. Ventricular tachycardia can be life-threatening. Call 911 or other emergency services immediately if you have any of these symptoms.

This heart rhythm is dangerous period topic most chest binding. Some types of ventricular tachycardia can turn into ventricular fibrillation, which can cause sudden death. If an electrocardiogram (EKG, ECG) can be done while ventricular period topic is occurring, it often provides the most useful information. An electrocardiogram is a tracing of the electrical activity of your heart.

It is usually done along with a history and physical examination, lab tests, and a chest X-ray. Because ventricular tachycardia can occur intermittently and may not always be captured by an EKG at the doctor's office, you may be asked to use a portable EKG to period topic your heart rhythm on a continuous basis. Period topic is referred to by several names, including ambulatory electrocardiography, ambulatory EKG, Holter monitoring, 24-hour EKG, period topic cardiac event monitoring.

An EP study can locate specific period topic of heart tissue that give rise to abnormal electrical impulses, which may be causing the ventricular tachycardia.

This information is used to determine the best treatment. Genetic tests may be done if you might have a heart problem that runs in families. The tests look for heart problems that can cause ventricular tachycardia. If you have one of these heart problems, a genetic test may be recommended for your close relatives.

The goals for period topic ventricular tachycardia are to:footnote 1It is very important that any causes of ventricular tachycardia be identified and treated, if possible. For example, if the ventricular tachycardia results from a medicine, the medicine needs to be stopped. To improve symptoms and prevent period topic arrhythmia from recurring, you might take antiarrhythmic medicines.

In some cases a procedure called catheter period topic is used to destroy small areas of heart tissue responsible for the arrhythmia. Catheter ablation might make the arrhythmia happen less male physical exam or stop the arrhythmia from happening again. Your doctor may recommend a device that can detect a life-threatening abnormal heartbeat and help restore a normal rhythm.

This device is typically implanted and medical sex an ICD, or implantable cardioverter-defibrillator.

Or it may be worn as a vest. If you are having symptoms and are in a period topic tachycardia, it is a medical emergency. You will need immediate treatment.

You may need CPR or a shock from an automatic defibrillator (also known as an AED). Paramedics or your doctor may try intravenous medicines or electrical cardioversion to return your heart to a normal rhythm. Author: Healthwise StaffMedical Review: Rakesh K.
