For what reasons does the heart fail with a normal rhythm, varieties of arrhythmia
Almost all people in old age and often even young ones experience heart rhythm disturbances, which can occur in different ways. What causes contribute to the violation of the rhythm, as classified and treated, read in this article.

Types of arrhythmias
The following types of arrhythmias are distinguished:
- Atrial fibrillation.
At a ciliary arrhythmia there can be sensations of that the heart trembles: that is accelerated, it stops. Frequent symptoms - dizziness, oxygen deficiency (the patient can even cough) and pain in the chest..
Important!The flow of atrial fibrillation without symptoms does not mean that it is safe for health.
At flickering, cardiac contractions increase to 120-150 beats per minute or more. This causes overload in the work of the heart, which can be complicated before a stroke or myocardial infarction. The disease proceeds stably or in the form of paroxysms (severe contractions).
Causes of atrial fibrillation may include the following:
- Heart defects.
- Thyroid gland disorders.
Often attacks of atrial fibrillation occur with hypertensive crisis or during an attack of myocardial infarction. Sometimes the cause is chronic stress or alcohol abuse, leading to disruption of the vegetative-nervous system of the heart.
The symptom of tachycardia is a rapid heartbeat. At the same time, the heart rate does not go astray, it is simply accelerated. In a healthy person, normal heart rate is within 60-80 beats per minute. Each individual rhythm is individual, determined by age, physiological parameters, way of life. If the heart rate exceeds 90 beats per minute, then this is a tachycardia.
It would seem that the rhythm simply accelerated, and the heart works more actively, but it does not bode well, since the ventricles suffer from a lack of blood supply. This can lead to heart failure. In connection with the deterioration of blood circulation, the organs will not have enough oxygen, including myocardium, which can even lead to a heart attack.
Tachycardia occurs for simple reasons. Often overburdened physical exertions lead to strong heartbeats, as if jumping out. Stressful situations and being at high temperatures can cause heart palpitations. For example, when the body is heated by 1 degree, the heart gives 10 additional cuts per minute. It is not necessary to reject the possibility of influencing infectious diseases, including those accompanied by fever.
Diseases of the thyroid gland, which lead to hyperthyroidism, also cause tachycardia. If the body has a higher calcium content, then there is an increase in the pulse, since its free ions are responsible for the transmission of nerve impulses between the cells of the myocardium.
Attention!Bradycardia and tachycardia are different manifestations of arrhythmia. If tachycardia causes an increase in heart rate, then bradycardia - a decrease. You can not confuse these concepts..
If the heart rate has dropped below 55 beats per minute, then a bradycardia is diagnosed. Because of insufficient circulation, oxygen deficiency of the brain, heart and other internal organs occurs. With a rare heartbeat, dizziness occurs until loss of consciousness.
The causes of bradycardia are inflammation of the gallbladder and abnormalities in the work of the stomach. If there are no problems with these organs, then the occurrence of bradycardia can be associated with angina or inflammatory processes in the myocardium. Hereditary heart defects can also cause a bradycardia. Often cicatricial changes in the cardiac tissue after necrosis of the myocardium cause bradycardia, since transmitted impulses can not reach the ventricles in full.
There is a kind of arrhythmia, which differs from others in that the violation of the heartbeat does not occur by accelerating or slowing the existing rhythm. The reason lies in the "wedging" of contractions in the normal rhythm caused by extraneous impulses.
During the extrasystole, jerking sensations in the chest and heartbeats are felt. In some cases, the heart seems to freeze for a second, after which the heart rate is greatly accelerated. Because of the occurrence of extrasystole, the ventricles can not be filled with the necessary amount of blood. This is due to the absence of rest breaks between cuts.
Often the causes of extrasystole are chronic fatigue and accumulated stress. They do not pose a threat to life, but they still need to be damped, so that complications do not arise due to worsening of blood circulation.
In this case, it can be noted that extrasystole is considered normal if there are no more than a thousand extrasystoles per day. If extraordinary cuts appear very often, this is already a threat. To calm and suppress extraordinary impulses, you need to drink a sedative, for example, 10-15 drops of valerian tincture with water.
Many patients with irregular heartbeats who are asymptomatic are diagnosed with a "blockade". What does this mean? The fact is that the contraction of the ventricles is caused by impulses that come from the driver of the rhythm (sinoatrial node) located in the atrium.
The generated impulses are transmitted to the ventricles along the AV node, which can partially or completely block. When an incomplete blockade occurs, only a part of the impulses do not reach the ventricles. A complete blockade blocks the way to all impulses. Against this background, a bradycardia develops, which almost imperceptibly passes for a person.
There is a blockade for many reasons:
- Angina pectoris.
- Myocardial infarction.
- Excessive stress on the heart.
Why rhythm is lost, and how the arrhythmia is distinguished into several types, look at the video:
Treatment: what to do if the heart rate is lost
If a patient has a cardiac rhythm disorder, the doctor prescribes electrocardiography to clarify the reasons and confirm the diagnosis. To determine the localization of pathologies that caused a rhythm disturbance, ultrasound of the heart is performed.
If a normal ECG does not detect a violation, daily monitoring using the Holter method is performed. This is because the attack occurs periodically, especially in the early morning or at night.
Since all the processes taking place in the body are interconnected, the cardiologist can send in addition to other specialists. For example, with stomach ulcers or pancreatic ailments, the heart often gets knocked off the rhythm.
If the arrhythmia is caused by other serious diseases, then you need to treat them. Eliminating or coping the underlying ailment, it will be possible to restore the heart rhythm. If you do not approach treatment in a complex way, and try to eliminate only the symptoms with antiarrhythmic drugs, complications may appear..
Important!Medication should be taken strictly according to the doctor's prescription..
Sometimes antiarrhythmic medicines have a short and unstable effect, which is followed by subsequent malfunctions. Possible side effects. For example, the common remedy for atrial fibrillation "Cordarone" can harm the thyroid gland.
Among the drugs used in arrhythmia, in particular, at ciliary, means are found to reduce the viscosity of the blood. In this case, when passing therapy aimed at reducing the risk of thromboembolism Warfarin, you need to monitor the INR index. It should be within 2-3. At an intoxication prepaatom it is possible a hemorrhage in a brain.
After a successful arrest of the disease and for preventive purposes, a lifestyle must be reconsidered. First of all, it is recommended to exclude conflict and stressful situations. Doctors do not recommend tedious activities. It is necessary to spend more time in the fresh air, to make up for the deficiency of oxygen in the body.
Favorable for blood circulation is influenced by physical therapy. People suffering from tachycardia are not recommended to drink coffee, strong tea and other beverages that stimulate the heart.
To eat it is necessary measuredly and often, that the stomach did not test strong loads. Every year, a sanatorium treatment is recommended where you can undergo therapeutic procedures or take an active and wellness vacation... .
