How dangerous tachycardia of the heart?
Faced with the conclusion about tachycardia, many wonder how it is dangerous and what is tachycardia. This increased the number of heart beats in one minute. It is worth noting that the normal number of heartbeats for an adult is 60-90 beats. Tachycardia is not a disease, a symptom of the disease. There are two types of palpitations:
- physiological (normal) is when the heart rate increases during exercise, illness or stress;
- pathological is when a person is in a state of peace and relaxation, and heart rate still higher than normal.
Thus, the first type curing is not necessary, but the second requires a full medical examination to learn about the possible outbreak of a serious disease. To answer the question, what is the danger of tachycardia, you need to determine what are its causes and symptoms.
Experts distinguish several types of tachycardia:
- A hub;
- tahisistolicescie form of atrial fibrillation.
Sinus tachycardia is characterized by a flat heart rate with a frequency of more than 100 beats per minute. This form of rapid heart rate is common among young people and reaches 200 beats.
Atrial tachycardia is characterized by sudden beginning of the attack and the same unexpected ending. During the regular bouts of heart rate varies from 160 to 220 beats a minute, the attack can last from several minutes to several hours.
A-V nodal tachycardia is a common form of supraventricular arrhythmias, it does not depend on the age of the patient, presence of other diseases. However, this form is more common in women. Heart rhythm is correct, and the frequency of beats per minute from 120 to 250.
Ventricular tachycardia is a dangerous form of heart palpitations. Due to the fact that the lower chamber of the heart is shrinking fast, they can’t completely fill with blood. As a result, the heart muscle is inefficient, vital organs do not get required amount of blood. All this leads to complications. The transition of ventricular tachycardia to ventricular fibrillation may cause death.
Tahisistolicescie form of atrial fibrillation – a form of atrial fibrillation, with heart rate over 100 per minute. More common in the elderly and is caused by various cardiovascular diseases such as heart disease, coronary artery disease or heart failure.
Causes of palpitations
The emergence of palpitations (most often sinus tachycardia) when a person is in a state of complete rest, the evidence of such diseases as:
In addition, the development of tachycardia contributes to a strong intoxication from Smoking, excessive alcohol consumption, caffeine, energy drinks.
What are the symptoms of tachycardia?
The main symptom is a rapid heart rhythm, but there are other signs:
- the constant feeling of shortage of air;
- the occurrence of seizures surges in heart rate, after which the rhythm returns to normal;
- unexpected attacks faint and dizzy;
- the sense of panic and fear;
- discomfort and pressing chest pain.
There are the following types of diagnosis of tachycardia:
ECG helps to determine the kind of palpitations, frequency and rhythm. Also, thanks to electrocardiography it is possible to obtain information about possible hypertrophy of the left or right ventricle and myocardial.
Daily ECG monitoring helps to find and analyse any heart rhythm disturbances. In addition, to track changes in the heart muscle during physical or emotional exertion, during rest and sleep.
Intracardiac pathology determined by echocardiography. Using Echo to find out the thickness of the walls of the heart, the condition of the valves and soft tissue, the contractility of the myocardium. Echocardiography allows to visually assess the heart muscle, speed and movement of blood in the Atria and the ventricles.
Using electrophysiological studies of the heart can be learned about possible violations conductivity cardiac muscles and the mechanism of tachycardia.
What is dangerous heart palpitations
Do not leave without attention the attacks of tachycardia, having a systematic. This expression complicates the work of the heart.
So, what is it that dangerous tachycardia? In addition to the unpleasant feelings that accompany the patient, it causes the heart muscle can no longer cope with its function. And becomes vulnerable and wear out.
If the person is a long time suffers from tachycardia, after a time, he has heart failure .
In case of palpitations on a background of chronic heart failure poses a number of serious complications, such as:
- acute failure of the left ventricle, in the form of pulmonary edema or cardiac asthma;
- arrhythmic shock;
- acute insufficiency of brain blood flow may cause loss of consciousness.
In paroxysmal atrial fibrillation the possible complications leading to ischemic strokes. Consequences of ventricular tachycardia, particularly after myocardial infarction can become ventricular fibrillation. This complication tachycardia is the most dangerous as it can cause sudden death.
Prevention and treatment
For the treatment of tachycardia the cardiologist prescribes medicines belonging to the group β-blockers, and calcium antagonists. β-blockers reduce heart rate, so they are often prescribed for tachycardia. Effective especially Propranolol and Bisoprolol.
Calcium channel blockers are used in cardiology for several decades. With palpitations effective drugs Verapamil and Diltiazem.
Sometimes the treatment of tachycardia requires surgery, for example, in paroxysmal tachycardia radiofrequency ablation carried out. Radiofrequency ablation is an effective method for the treatment of heart rhythm disorders. During the operation through a vessel in the cavity of the heart introduce a thin catheter, it is the momentum that destroys the area of the myocardium that is responsible for the abnormal heart rhythm. This type of surgery has no complications, and patients tolerate easily.
As a prevent bouts of tachycardia, the doctors suggest in case of symptoms immediately be examined. And more fresh air, exercise, give up bad habits, follow a proper diet and have good sleep and rest. All this helps in the prevention of heart palpitations and other problems associated with the cardiovascular system.
