Causes of an irregular heartbeat

Arrhythmia is known medically as arrhythmia, as a group of conditions in which the heartbeat is irregular, or very slow, or faster than normal, and accordingly, arrhythmia can be divided into several sections, namely: bradycardia Tachycardia, an irregular heartbeat, which includes flutter or tremor and early contractions, and it can be said that most cases of arrhythmia are not dangerous, but some of them can increase the chance of a stroke or cardiac arrest, and in fact the symptoms associated with arrhythmia vary accordingly. Irregular type; For example, tachycardia may cause shortness of breath, dizziness, fainting, chest flutter, feeling chest pain, lightheadedness, and sudden weakness, while bradycardia may cause angina, difficulty concentrating, confusion, difficulty exercising, dizziness, fatigue and fatigue, lightheadedness, and palpitations. Heart failure, shortness of breath, fainting, and sweating.

Causes of an arrhythmia:
 The heart rate can be regulated through a complex and elaborate electrical system, so that it ensures the contraction of the different heart chambers in a coordinated manner, completely. The heart rhythm is greatly efficient, and as a result of this complex and delicate system of heart electricity, any malfunction or defect in the electrical system of the heart can cause an irregular heartbeat, and the following is a detail of the various causes of arrhythmia:

Imbalance of the autonomic nervous system:
As the autonomic nervous system controls bodily functions that we do not think about, such as: breathing, sweating, and heart rate, and in fact, tachycardia may arise from hyperstimulation of the sympathetic nervous system, and severe tension or sudden fear leads to an increase in the secretion of the hormone adrenaline, This causes tachycardia, while bradycardia can be caused by hyperstimulation of the vagus nerve, and factors that stimulate the vagus nerve include vomiting, severe constipation, and urethral obstruction.

Some cases of arrhythmia are common in people under general anesthesia, for many reasons, including the effect of the substance itself, electrolyte disturbances and metabolic disorders that may occur during anesthesia, fluctuations in blood pressure that may occur during anesthesia, and heart damage. And blood vessels during surgery, especially heart surgery.

Heart disease:
Different types of heart disease can affect the heart's electrical system, causing an irregular heartbeat, and functional heart disease is the most common cause of serious heart rhythm disturbances. Examples of these diseases are coronary artery disease, cardiomyopathy, and heart valve disease, It is worth saying that the risk of sudden death is high for people who have had a heart attack or heart failure as a result of the irregular heartbeat caused by these two problems.

Genetic disorders:
Many genetic mutations can cause arrhythmias that are known to be hereditary. Examples of genetic arrhythmias are: long QT syndrome, Brugada syndrome, and sick sinus syndrome.

 Aging and aging can cause myocardial fibrosis, leading to an irregular heartbeat. Metabolic or electrolyte disturbances: Electrolyte disturbances or acidity of the blood can cause an irregular heartbeat, especially in patients who have kidney disease, diabetes, or are taking certain medications, such as: diuretics, are dehydrated, or are ill Severe, examples of these disorders are hypokalemia, hyperkalemia, hypomagnesemia, hypocalcemia and acidosis, and increased alkalinity of the blood.
