Heart diseases



tachyarrhythmia photo Tachyarrhythmia - a pathological heart rhythm disorder, which is characterized by a significant increase in heart rate, while a violation of their periodicity.If tachyarrhythmia heart rate ranges from one hundred to four hundred beats per minute, and pathologically rapid heart rate can be observed in the lower chambers of the heart (ventricular fibrillation), and the upper chambers (atrial fibrillation).

Tachyarrhythmia reasons

abnormally rapid heart rhythm may develop due to various diseases of the heart.Most often the development of this pathology provoke following heart diseases: infectious and neoplastic lesions of the heart muscle, cardiomyopathy, heart failure, atherosclerosis (coronary artery disease), high blood pressure and heart valve disease.

addition to the causes of tachyarrhythmias include some lung disease, thyroid disease, hyperthyroidism, electrolyte imbalance, congenital WPW-syndrome, heart surgery, the use of drugs and alcohol.

Tachyarrhythmia manif

ests itself in the event that shortens the heart muscle impulse arrives before it assumes a normal heart rhythm.This abnormal rhythm of the heart may begin in the lower and in the upper heart chambers.

Tachyarrhythmia symptoms

This state can be divided into chronic and paroxysmal, with chronic tachyarrhythmias can be constant and continuous-recurrent.The clinical picture is variable enough, from mild palpitations to severe weakness, breathlessness, fainting, arrhythmic shock and pulmonary edema.Often, there is shortness of breath and dizziness.

addition to tachyarrhythmia characterized by symptoms of so-called "vegetative storm", often with a shiver, fever, urgency to urinate, with the release of a large number of urine.

sinus tachyarrhythmia

One of the common types of cardiac arrhythmia is sinus tachyarrhythmia.This condition is characterized by rapid heart rhythm, above eighty beats per minute.

When this increase in heart rate observed during physical exertion, anxiety, stress or excitement - this is normal.But if this situation is evident at rest, should be wary, becauseoften it is the first manifestation of sinus tachyarrhythmia.

In most cases, this type of arrhythmia indicates the presence of problems in the thyroid gland, the autonomic nervous system, blood circulation.In this case, the appearance of palpitations should seek the help of a cardiologist, who after the necessary investigations prescribe appropriate treatment or refer to another medical specialist (endocrinologist phlebologist etc.).

sinus tachyarrhythmia is very dangerous because when the hard work, the heart is not filled with the right amount of blood, which entails as a worsening of blood supply to the heart muscle itself, and other organs and tissues.Consequently, it may initially develop myocardial ischemia, and later myocardial infarction.

Tachyarrhythmia in children often is neparoksizmalnuyu and paroxysmal tachycardia.These states require mandatory treatment or sometimes even emergency care.Paroxysmal tachyarrhythmia starts suddenly as a result of pre-excitation syndromes or after the beats.Most often, the attack lasts seconds, but can sometimes be delayed for two or three hours, then just as suddenly come to an end.During the attack, the heart rate exceeds the age limit is usually two-fold.

Neparoksizmalnaya tachyarrhythmia in children develops as a result of the activity of heterogeneous foci of automatism.The attack in this form of the disease has been delayed for a long time, began his slow heart rate can reach 160 beats per minute, in the end there is no compensatory pause.In the case of frequent prolonged attacks may develop heart failure.

Tachyarrhythmia treatment

diagnosis and subsequent treatment of tachyarrhythmia holds a cardiologist.Tactics of treatment depends on the underlying pathology diagnosed which caused the violation of cardiac rhythm.

If tachyarrhythmia not lead to an acute circulatory disorders and there is no immediate threat to his appearance, carrying emergency antiarrhythmic therapy is not carried out, asin such cases, attempts to normalize emergency rate may be much more dangerous than the arrhythmia.
