Understanding Cardiac Arrhythmia: Symptoms, Causes, and Prevention

Cardiac arrhythmia is a common topic and often surrounded by doubts and concerns. Many people wonder what symptoms may indicate a more serious condition, when it is necessary to take action, and whether treatment or frequent visits to the cardiologist are essential. According to the Israelite Albert Einstein Hospital, in Brazil, there are more than 2 million cases of arrhythmia reported each year.


In simple terms, cardiac arrhythmia is characterized by the sensation that the heartbeats are faster than normal. This sensation can be uncomfortable, and some people also notice the absence or sudden interruption of heartbeats. Arrhythmia can be felt in the neck, chest, or throat.


The Nature of Arrhythmias


In general, most arrhythmias are not considered a serious condition as long as the person is stable. Under normal conditions, the heart beats between 60 and 100 times per minute. People who exercise regularly or use medication to slow down the heart rate may have a heart rate of less than 55 beats per minute.

If the heart rate exceeds 100 beats per minute, this is called tachycardia. On the other hand, a heart rate of less than 60 beats per minute is classified as bradycardia.

It is important to understand that arrhythmia can be a symptom of a physical or psychological problem, or even indicate an imbalance in the heart. People with a family history of cardiovascular diseases are more predisposed to developing arrhythmias.


Causes of Cardiac Arrhythmia


The causes of cardiac arrhythmia can be diverse and vary from person to person. Some of the main causes include:


  1. Use of weight loss pills;
  2. Anxiety, stress, and fear;
  3. Anemia;
  4. Excessive physical exercise;
  5. High fever;
  6. Over-ventilation;
  7. Low blood oxygen levels;
  8. Heart valve diseases, including left atrioventricular valve prolapse;
  9. Overactive thyroid.


Prevention and Risk Reduction


Fortunately, there are ways to prevent and reduce the risk of developing arrhythmias. Some measures include:


  1. Avoiding excessive alcohol consumption;
  2. Quitting smoking;
  3. Maintaining a healthy weight;
  4. Adopting a balanced and healthy diet;
  5. Controlling diabetes and hypertension if these conditions are present in the individual’s life.


Practicing a healthy lifestyle and paying attention to underlying health conditions are important steps to avoid or minimize the risk of cardiac arrhythmias. Additionally, it is essential to regularly consult a cardiologist, especially for individuals with a family history of cardiovascular diseases, to monitor heart health and take appropriate preventive measures.


Preventing Arrhythmias


Cardiac arrhythmia is a common condition that can cause discomfort and concern. However, in most cases, arrhythmias are not serious and can be controlled with simple preventive measures. A healthy lifestyle, quitting harmful habits such as smoking and excessive alcohol consumption, and regular consultations with a cardiologist are crucial factors in maintaining heart health and preventing complications from cardiac arrhythmias.


Those who experience symptoms of arrhythmia or have a family history of cardiovascular diseases should seek medical guidance for an accurate diagnosis and an appropriate treatment plan, ensuring a more peaceful and healthy life. Take care of your heart and live well!
