Arrhythmia is mostly caused by heart disease, especially coronary artery disease, heart valve disease and heart failure. Some arrhythmias are caused by congenital defects. This article focuses on the causes of arrhythmias.
What is arrhythmia
Arrhythmia is caused by abnormal activation of the sinus node, that is, impaired activation of the conduction, resulting in abnormal heart beat frequency and rhythm. Arrhythmia can occur alone or sometimes concurrently with other diseases. The prognosis of arrhythmia has a lot to do with the cause, inducement, evolution trend, or whether it leads to more serious blood flow disorders. therefore. Arrhythmia can lead to sudden sudden death, or continuous involvement of the heart eventually leads to heart failure.
Why does arrhythmia occur
(1) Heart problems
Coronary artery disease, stenosis of the heart arteries, heart attack, abnormal heart valves, heart failure, cardiomyopathy, and other myocardial damage can all cause arrhythmia. In addition, patients with congenital heart disease and heart abnormalities at birth can also affect the rhythm of the heartbeat.
Some other prescription drugs are likely to cause arrhythmia. If such drugs include drugs for the treatment of heart diseases, they may cause arrhythmia.
(5) Electrolyte imbalance
The blood contains electrolytes such as potassium, calcium, sodium and magnesium, which help the conduction of electrical impulses in the heart. Electrolyte imbalance can cause arrhythmia.
Caffeine, nicotine, and other stimulants will speed up the heartbeat of the patient, and will further cause arrhythmia. There are also some illegal drugs, such as amphetamine, cocaine, etc., which can affect the heart and cause arrhythmia.
(7) Lack of sleep
Endocrine disorders can also cause arrhythmia. Under normal circumstances, various hormones maintain balance through feedback regulation mechanisms. For example, if this balance is broken for some reason (too much, too little, or hormone resistance), it is called endocrine disorders. Among them, lack of sleep will increase the body’s burden and cause endocrine disorders. Decreased heart function can also cause arrhythmia. In this regard, patients should adjust their endocrine function in their daily lives to avoid arrhythmia caused by endocrine disorders.
(8) Other reasons
Exercise or emotional stress may also cause arrhythmia. In addition, excessive drinking can affect the heart and cause atrial fibrillation. Arrhythmia caused by overstimulation of the vagus nerve is generally accompanied by symptoms such as pain, hunger, fatigue, and digestive disorders, such as diarrhea and vomiting. The arrhythmia caused by this condition usually goes away on its own. Obstructive sleep apnea caused by interrupted breathing during sleep increases the risk of bradycardia, atrial fibrillation, and arrhythmia.
Modern medicine believes that when people are emotionally excited and mentally excited, the sympathetic nerves are often more excited. At this time, it is very easy to have problems such as increased heart rate and increased blood pressure. At the same time, it may be accompanied by a shortened diastolic period, which may cause Arrhythmia. Promote the increase of cardiac contractility, thereby increasing the amount of myocardial oxygen consumption, making the heart beat faster and accompanied by arrhythmia.
There are many reasons for arrhythmia, most of which are related to our living habits. People should develop good habits in daily life to avoid the occurrence of arrhythmia.
