Signs of this pathological condition found among the elderly and young people.Cardiac arrhythmia, symptoms that bother many people, basically a violation of myocardial function as automatism, excitability and conductivity.The reasons for this may be different.Primarily, this organic and functional changes in the heart and the conduction system.For example, myocardial ischemia, infarction, cardio, inflammatory changes of the myocardium and valves, heart disease, myocardial, pulmonary heart.
can lead to arrhythmias and dysregulation of the heart.They are associated with psycho-emotional stress, diseases of the autonomic or central nervous system, endocrine glands and other organs.For example, beats often in menopause;paroxysmal tachycardia uncommon in diseases of the thyroid gland.
Arrhythmias may occur under the influence of drugs (digitalis, beta-blockers, and others.) And toxic substances.
cardiac arrhythmia, symptoms of various forms that are often similar in origin divided into different forms:
- related disorders myocardial automaticity.These include sinus bradycardia and tachycardia, respiratory arrhythmia of the heart and some other types of violations.
- related to violation of excitability.They are represented by premature beats and paroxysmal tachycardia.Available in
- based cardiac conduction disorders.These types of arrhythmias are Sino-auricular, intraatrial, incomplete and complete atrioventricular and intraventricular blocks.
- cause disturbances and irritability, and conductivity: fibrilloflutter and ventricles.
- caused by disturbance of cardiac contractility: alternating and paradoxical pulse.
several dozen kinds of cardiac arrhythmias.We shall touch upon those features that occur most frequently.
With such diseases as cardiac arrhythmia, the symptoms are as fast or slowing its rate, violating their correct sequence.Sometimes patients do not feel them, they are only detected on an electrocardiogram.However, in some cases, they represent a danger to the state and even the life of the patient.
When tachycardia pulse quickens.If normal heart rate is 60-80 beats per minute, when he can paroxysmal tachycardia to 160-200 more frequent and more punches.It violated the right rhythm.The patient appears the fear of death.
If bradycardia heart rate, on the contrary, is slowing.
When respiratory arrhythmia heart rate slows inspiratory and expiratory quickens.
When arrhythmia patients complain of shortages in the heart and a sense of his fading.They are associated with the occurrence of an extraordinary reduction in the atria or the ventricles and the following so-called refractory, period.
With heart block heart rate slows down, there is a sensation of fading heart.Depending on the extent of the blockade, these symptoms can be added dizziness, fainting, darkening of the eyes.
few words about what is dangerous cardiac arrhythmia.As already mentioned, it has different causes and is often indicative of severe lesions of the heart or other body systems.
In addition, sometimes there is an arrhythmia of the heart, symptoms of which may be life threatening.So, ventricular premature beats or ventricular fibrillation can cause cardiac arrest.Atrial fibrillation can lead to heart failure and pulmonary edema.Some forms of arrhythmias become a cause of sudden death.
In each case, questions to diagnose and treat arrhythmias should decide cardiologist.Be attentive to your health!
