Understanding Sinus Arrhythmias, Heart Disorders Without Symptoms

Sinus arrhythmias are changes in the heart's rhythm to be faster or slower. This condition is generally harmless and is not a sign of serious heart problems.

Sinus arrhythmias are closely related to sinus function which refers to a part of the heart called the sinoatrial node, which is a natural pacemaker found in the wall of the right atrium of the heart. Sinuses control the rhythm of the human heart. Under normal conditions, the heart should have a stable sinus rhythm.

Sinus Arrhythmias Rarely Cause Symptoms

Sinus arrhythmias are related to the heart and respiratory system. A person's heart rhythm increases when he inhales and decreases when he exhales. Sinus arrhythmias can occur in the form of sinus bradycardia or a slow heart rhythm, which is below 60 beats per minute, and sinus tachycardia or a fast heart rhythm, above 100 beats per minute.

The cause of sinus arrhythmias is still unknown. Most sufferers also rarely complain of heart problems, as in other heart diseases. Although it can occur for no apparent reason, there are several things that can affect the onset of sinus arrhythmias.

For example, sinus bradycardia can occur in:

  • People who exercise regularly. With excellent physical condition, generally the heart does not need to work hard to pump blood throughout the body, so the heart rate tends to be slower.
  • People who are taking certain medications, such as drugs for heart and blood vessel disease.
  • People with heart block, low blood sugar levels (hypoglycemia) or sleep apnea.

While sinus tachycardia can occur when a person:

  • Exercising, or doing strenuous activities
  • Feeling excited, painful, or anxious
  • Have fever, hypoxia (lack of oxygen), excessive thyroid hormone production (hyperthyroidism)
  • Consuming caffeine.

Sinus arrhythmias are generally discovered incidentally when a doctor performs an examination or diagnosis when a patient complains of a heart problem.

One of the medical procedures that can assist doctors in diagnosing sinus arrhythmias is an electrocardiogram (ECG). This tool serves to read the electrical signals of the heart, so that any abnormalities related to heart rhythm can be detected.

The Right Way to Handle Sinus Arrhythmias

Sinus arrhythmia is not a dangerous disease that requires special treatment. This condition is a sign or symptom of a physical condition that can be normal due to various factors, although in some cases it may indicate heart disease.

Doctors will provide treatment if this condition is influenced or occurs in conjunction with certain heart diseases. Treatment efforts are carried out depending on the type of heart disorder that causes sinus arrhythmia.

Sinus arrhythmias generally go away on their own without special treatment. In many cases, people with this condition can also live a normal life without experiencing heart problems. Even so, you should consult a doctor if you feel other symptoms, such as shortness of breath, chest pain, dizziness, and fainting.

Sinus arrhythmia is not a condition to worry about. However, if there are disturbing symptoms, you should consult a doctor. In addition, try to maintain a healthy heart, by exercising regularly and eating healthy and nutritious foods, such as green vegetables, whole grains, avocados, fish, or whole grains.
