Normally, cardiac arrhythmia is considered a type of heart disease. It occurs when there are some points or positions in the heart that generate an abnormal electric current or there is a small short circuit in the heart. Because such abnormalities are tiny, it does not affect the heart function, which is different from other heart diseases with large pathology, like heart valves, heart muscle, or coronary artery, which occur with abnormal heart function.
Symptoms of cardiac arrhythmia
• Slow heart rate lower than 60 beats/minute. Symptoms include feeling confused, light headedness, flashing, and low blood pressure. If serious, fainting and unconsciousness may occur. In those with minor symptoms, they may only feel fatigue or tired easily.
• Fast heart rate more than 60 beats/minute. If minor, you may get tired easily and have fast heartbeat. If serious, there will be chest pain, wooziness, low blood pressure, heart attack, or sudden death. If you suspect you have an abovementioned symptom, see a doctor to check your history and have a thorough physical check-up. In case of feeling flashing, fainting, or unconsciousness; having severe palpitations; or being out of breath, see a doctor immediately.

Main causes of cardiac arrhythmia
• Heredity, which is an abnormality of the heart circuit since birth
• The deterioration of the heart electrical system, which often occurs in elderly people and is the cause of slow heart rate. Because the heart has been working for a long time, it deteriorates with age. The energy level that stimulates the heart becomes less, which leads to abnormally slow beating of the heart.

• Some types of disease cause arrhythmia, such as coronary artery disease, high blood pressure, dyslipidemia, diabetes or in those with abnormal function of thyroid gland.
• Taking some types of medication or addictive substances can cause arrhythmia. For example: Common cold medicine, bronchodilators, or medication that stimulates the heart.
Diagnosis of cardiac arrhythmia
• Electrocardiogram is used to detect the electric current that is released from the heart. Our heart consists of the strong heart muscle that works all the time. The contracting of the heart relies on electricity. This electricity comes from the heart, which will be released rhythmically from the right atrium to the ventricles. While the electricity flows through the heart muscle, the heart muscle will contract and loosen. The heart will squeeze the blood from the atriums to the ventricles together. When placing the electrical receptor near the heart, it can record the electricity that is released from the heart.
• 24-Hour Holter Monitoring is a 24-hour electrocardiogram to diagnose cardiac arrhythmia and find out the cause of the palpitations and flashing. The 24-hour electrocardiogram can be done by installing the 24-Hour Holter Monitoring device with the patient to take home or go to work as normal without being admitted in the hospital. When completing 24 hours, the doctor will remove the device and diagnose the result. This method is suitable for patients who occasionally have abnormal palpitations or always feel like fainting or dizzy, or whose heart always beats abnormally fast. Sometimes, these symptoms are not found in the electrocardiogram. When there are no symptoms, everything looks normal. Therefore, it is not known whether the palpitation occurs from the cardiac arrhythmia or not.

The treatment is divided into 2 groups
The treatment can be done by making the heart beat normally again by using medication, electricity, or radio waves. Moreover, treatment by medication may be considered to control the heart from beating too fast only. In some cases, thrombolytic drugs are needed. Hence, the treatment in each case will depend on the nature of the patient and doctor performing the treatment. However, there are many different treatment methods for cardiac arrhythmia. Try to avoid stimulants that cause cardiac arrhythmia, such as stress, some types of medication, tea, coffee, and alcohol.
