Supraventricular tachycardia - Either an independent disease that occurs due to abnormalities in the structure of the heart, or a consequence of other diseases for which a negative effect on the heart. In this form of tachycardia heart abnormal rhythm of the heart is not formed above the ventricles, ie at the level of the atria.

With Ventricular tachycardia and   more frequent source of rhythm is already in the ventricles. This condition is considered serious enough violation of the heart.

Ventricular tachycardia is sometimes seen as an anomaly inherent nature and consequence of diseases affecting the heart muscle. Most often this form of tachycardia is a consequence of cardiac ischemia   or cardiomyopathy . Manifestations of ventricular tachycardia pose a risk to the patient because of the potential disruption of the heart rate and, as a consequence, the possibility of sudden cardiac arrest.

Sinus tachycardia

Sinus tachycardia   - A condition in which the acceleration of the heart rate is due to external displays. Thus, it may be strong stress , Physical activity, and others. In this case, it is important to know what is the cause of such a state. That's the reason you need to remove in the first place, so the manifestations of sinus tachycardia requires a comprehensive examination of the body.

The cause of this condition - an increase of automatism sinoatrial node, which is the main pacemaker. If a person is completely healthy, the phenomenon may occur as a result of strong physical or emotional stress.

There are several types of sinus tachycardia. Pharmacological sinus tachycardia   arises as a consequence of influence on the sinus node adrenaline . noradrenaline . isoproterenol . alcohol . caffeine . Nicotine   and other substances. Provided as adequate and inadequate forms of abnormal sinus tachycardia. The appropriate form   tachycardia occurs as a consequence of increase in body temperature . hypertension . anemia . hypoxemia . thyrotoxicosis . For an inadequate form of sinus tachycardia is characterized by a persistent increase in the frequency of symptomatic sinus rhythm. The heart rate in this case is more than 100 per minute, both at rest and at least exertion. This state lasts for at least three months without any apparent reason.

Inadequate form   sinus tachycardia is relatively rare and is poorly understood disease. Typically, the disease occurs in young adults, in most cases, manifested in women. Patients complain shortness of breath , Persistent palpitations, a feeling of weakness and constant dizziness .

Also tachycardia may occur as a consequence of the treatment of certain medications.

There is also a tachycardia arising due to the presence of disease of the heart muscle or due to irregularities in the electrical conduction of the heart. Tachycardia heart - this is the first sign of cardiac decompensation.

Also, such a state is a result of shock or collapse (which may be fainting, bleeding etc.), As a result of the reflex to the lowering of blood pressure.

The tendency to tachycardia is a common symptom in people with vascular dystonia . Typically, in this case of younger patients. Palpitations observed in patients neuroses .
