Cardiac Arrhythmia – What it is, Symptoms and Treatments

Cardiac Arrhythmia – What it is, Symptoms and Treatments The symptoms of cardiac arrhythmia usually only arise when it is a malignant disease. In addition, it causes tiredness and a feeling of weakness, dizziness, malaise, fainting, fast or slow heartbeat , feeling of a lump in the throat, shortness of breath, chest pain, paleness and cold sweat.

These symptoms can affect people with a healthy heart or those with established heart disease, such as high blood pressure or heart failure , when symptoms can be more pronounced.

Causes of Cardiac Arrhythmia:

  • The causes of cardiac arrhythmia are diverse. Among them, it can be highlighted.
  • High pressure.
  • Coronary disease.
  • Thyroid problems such as hyperthyroidism.
  • Chemical imbalances in the blood such as altered sodium, potassium or calcium concentrations.
  • Some medications such as beta-blockers, psychotropics and amphetamines.
  • Birth diseases of the heart .
  • Vigorous physical exercise.
  • Complication after cardiac surgery.
  • Heart failure or history of heart attack.
  • Chagas disease.
  • Anemia.
  • Aging.

Other factors such as excessive consumption of caffeine, alcohol, drugs, cigarettes, anxiety and stress can also precipitate a cardiac arrhythmia .


  • To prevent cardiac arrhythmia , one should try to reduce stress and risk factors for heart disease:
  • Do not smoke
  • Eat a well-balanced, low-fat diet
  • Exercise regularly
  • Try practicing stress management techniques like yoga, tai chi, or meditation
  • Make sure your blood pressure and cholesterol level are under control.

Beware of Caffeine:  Coffee, tea, chocolate and soda contain caffeine and are known for their stimulating effects on our nervous system. Caffeine can also cause the heart to contract and beat faster, and is not recommended for those who suffer from Arrhythmia . The ideal is to ingest up to 300 ml per day, if everything is fine. Under suspicion, the ideal is to ask the cardiologist if there is a need to interrupt consumption.

Alcohol in Moderation:  Excessive consumption of alcoholic beverages is directly associated with Cardiac Arrhythmia . Atrial fibrillation is the most common arrhythmia in these cases. Excessive alcohol intake stimulates the adrenergic system (formed by brain receptors responsible for producing adrenaline), which will increase the heartbeat and worsen an arrhythmia.

Escape the “Fad  Diets: Very high calorie restricted or liquid-only diets can lead to metabolic disorders, nutrient deficiencies and dehydration – all of these conditions can alter your heart rate , both higher and lower. , generating or worsening a picture of Cardiac Arrhythmia . According to Jéferson, a diet low in vitamin E , C and B complex can interfere with blood pressure, raising the heart rate and causing arrhythmias.

Treatment:  There are two types of heart rhythm changes that require treatment. The first is the bradycardic syndrome in which there is a disturbance in the formation or conduction of the electrical impulse, such that the heart rate is always inappropriately low. When it is well established that this condition is transient and reversible (often caused by medication use), it does not deserve definitive treatment.

However, when there is no possibility of recovery, the only way to restore the proper heart rate is to place a pacemaker, that is, a microcomputer that has the ability to form electrical impulses and stimulate the heart chambers.

Another type of Cardiac Arrhythmia  that requires treatment is characterized by the occurrence of short circuits in the heart , which increases the number of beats. These episodes may be isolated (extrasystoles) or represent tachycardia attacks. The heart races, people experience palpitations, a feeling of discomfort, and sometimes presyncopal symptoms.
