Aetiology: why slows the heartbeat

Bradycardia refers to one of the human heartbeat – arrhythmia. The term itself means “slow or infrequent heartbeat”: doctors use this term as a clinical (when describing the condition of the patient), and in the interpretation of electrocardiogram (ECG). In bradycardia the heart rate is below 60 in 1 minute: suspect bradycardia can be counted pulse.

Why the heartbeat may slow: causes of bradycardia

Bradycardia may be physiological or pathological: physiological bradycardia often occurs in people who actively physically training. Also at rest, during sleep, the heartbeat slows down because the body’s need for oxygen at rest is reduced.

Pathological bradycardia develops in diseases of the heart (hypertension and atherosclerosis to coronary heart disease, myocarditis, heart attack, etc.), congenital heart disease. Also the slow heart rate may occur when taking some medicines, an increase in intracranial pressure, and certain diseases – influenza, hepatitis, hypothyroidism, in a state of shock after experiencing stress or fear, when fasting.

Symptoms of bradycardia: to what doctor to address

For bradycardia with a heart rate above 40 per minute, the person experiences dizziness, sweating, shortness of breath, weakness, aggravated by physical exertion. If more pronounced bradycardia may experience fainting due to oxygen starvation of the brain as the arrhythmia and slow the heart, the brain is insufficiently supplied with oxygen.In congenital abnormal heart rhythm without treatment in children can cause the formation of bodies, to slow down growth.

If you experience slow heart rate, you should see a cardiologist. If the doctor finds no pathology, then you will need to consult a neurologist to rule out or confirm autonomic disorders. Depending on the cause of bradycardia and the degree of its manifestation, the specialist will prescribe treatment. With frequent fainting and pronounced bradycardia discusses the implantation of a pacemaker. Initially, as you will undergo a number of diagnostic procedures.

That prescribed by a doctor and whether it is possible to avoid the development of bradycardia

To determine the slowness of the heartbeat will help elementary counting the pulse and diagnose the disease ECG. Also to clarify disease that caused the bradycardia, your doctor may prescribe echocardiography, stress test, Holter (daily) ECG mounting and other studies.

To reduce the risk of bradikardii means to reduce the risk of heart disease. Therefore, the prevention of cardiovascular disease, and bradycardia in particular, are:

  • avoiding harmful habits, especially Smoking
  • control of blood sugar levels, especially in diabetes
  • avoiding obesity and control over its own weight
  • physical activity
  • reducing the impact of stress
  • proper nutrition.

To reduce the risk of bradycardia in people who have heart problems will help doctor: there must be not only medication, but also special therapeutic exercise, diet.
