There are many clinical causes of arrhythmias, which can be seen in normal people without any etiology, but arrhythmias occur on the basis of abnormal impulse generation, abnormal conduction, and the coexistence of abnormal impulse generation and conduction. The common clinical triggers are as follows: 1, normal people: fatigue, strong tea, strong coffee, emotional excitement, insomnia, etc., often cause arrhythmias. 2, various organic heart disease.
Such as coronary artery disease, cardiomyopathy, myocarditis and wind heart disease. As the sinus node and conduction system are infringed by lesions, the basis of arrhythmia exists, and arrhythmia occurs under suitable conditions 3, phytonadic dysfunction: disorders in the regulation of the neuroendocrine system of the heart cause an imbalance in the ion balance of the heart, which induces the occurrence of arrhythmia 4, systemic or other systemic diseases: such as neurological diseases, endocrine system diseases generation, trauma, surgery, Cardiac catheterization can also induce arrhythmias. 5, drug effects: such as various anti-arrhythmic drugs, digitalis, epinephrine, norepinephrine, isoprenaline, dopamine, dobutamine, amrinone and milrinone can cause serious arrhythmias. Severe electrolyte and acid-base balance disorders: such as severe hyperkalemia and hypocalcemia can weaken myocardial contraction, produce intraventricular conduction block and lead to cardiac arrest. Severe hypokalemia can cause ventricular arrhythmias leading to ventricular fibrillation. Severe acidosis can directly inhibit myocardial contractility and reduce responsiveness to catecholamines, leading to cardiac arrest.
