Slow heartbeat

Slow heartbeat's disease overview

What is

What is a slow heart rate?

Normal heart has a pacemaker that helps it work regularly and rhythmically. The rhythm and rhythmic system of the heart includes sinus buttons, atrial buttons, his bundle and Purkinje network. The sinus button controls the rhythm, the impulses from 60-100 times a minute, the impulses are transmitted through the atrial node to the his bundle and the Purkinje network and spreads to the whole heart, resulting in a contracting heart. Some physiological conditions and pathology of the system or the system that affects the rhythm of the heart rate slowing down, which can affect hemodynamics in dangerous cases.

What is

What is the slow heart rate?

In adults, the sinus button clocked at 60-100 times a minute, so the normal heart rate also fluctuated in that range. The heart rate below 60 times is called a slow rhythm. In children and babies, heart rate changes with age. The faster the child's heartbeat, for example, babies with normal heartbeats from 120-160 times a minute. Therefore, it is called a slow heart rate in newborns when the heart frequency is less than 100 times a minute.

What is the effect of

What is the slow heart rate?

Slow heart rate may be physiological as in athletes, sports practitioners but can also be pathological. Slow heart rate will reduce heart supply, reduce cerebral perfusion and organs leading to reducing exertion, fatigue, heart failure, fainting and sudden death.

Causes of Slow heartbeat's disease

There are many causes of slow rhythm:

  • Ischemic heart disease
  • Myocardial disease is not due to anemia
  • Congenital heart disease
  • Degeneration of transmission system

    • Acute myocardial infarction

    Myocarditis

  • Vagus power

    • Due to some drugs: digoxin, sympathetic beta blockers ...

  • Poisoning some plants and herbs
  • Metabolic disorders: acidosis, hyperkalemia, hypothyroidism, hypothermia, hypoxemia ...

    • Symptoms of Slow heartbeat's disease

  • Tired of exertion
  • Dizziness, dizziness
  • Fainting,
  • Difficulty breathing
    • chest pain: may be caused by coronary artery disease, which can also be slow due to other causes of reduced coronary perfusion, causing chest pain

    People at risk for Slow heartbeat's disease

  • Elderly

    • Hypertension

    Diabetes

  • Smoking

    • Alcoholism

    Use some long -term drugs without testing: digoxin, sympathetic beta blockers, anti -arrhyths ...

    Prevention of Slow heartbeat's disease

  • Quit smoking
  • Control of blood pressure, blood sugar
  • Healthy diet: Reduce salt, limit animal fat instead of vegetable oil, eat lots of green vegetables
  • regular exercise; At least 30 minutes a day, 5 days per week

    • Diagnostic measures for Slow heartbeat's disease

  • Electrical electrocardiogram: is a simple means, easy to implement and must be done first. On the electrocardiogram can determine the heart frequency, signs of anemia heart disease, atrial block, signs of Digoxin poisoning ...

    • ECG Holter: Monitor ECG for 24 hours, to identify heart rate abnormalities, diagnosis of sinus impairment syndrome, transmission disorders ...

    Determination: can be diagnosed with some causes such as ischemic heart disease

    Slow heartbeat's disease treatments

    Depending on the patient's condition, may need emergency treatment, temporary pacemaker, permanent pacemaker

  • Hemodynamic disorders: Emergency medications such as atropine, adrenalin, dopamine depending on the case. Then need to place the temporary pacemaker
  • Adjust electrical disorders, alkaline balance, ..

    • Chronic slow rhythms, when symptoms have been related to a slow pace, treatment often requires permanent pacemaker transplanting. You can choose a one -chamber pacemaker, two chambers with different pacing settings. Some cases accompanied by severe heart failure, can implant the cardiac symmetry (CRT) when the heart function is sufficient: the heart function is less than 35%, QRS over 130ms, ...

  • Medical treatment with theophylline can be used in some cases of diagnosis, when signs related to an unclear slow rhythm
