心律失常的临床治疗（Clinical treatment of arrhythmia） Clinical treatment of arrhythmia Arrhythmia (arrhythmia) can be seen in all kinds of organic heart disease, among which coronary heart disease is more common. Surgical patients with coronary heart disease, cardiomyopathy and rheumatic heart disease are increasing, and all kinds of arrhythmias can occur during the perioperative period. In recent years, because of the deepening of basic research and the advent of new drugs, great progress has been made in the clinical treatment of arrhythmia. 1 kinds and mechanism of arrhythmia 1.1, the types of arrhythmia, clinical classification of arrhythmia are more, in general can be divided into sinus, atrial, supraventricular, ventricular and conduction block and other arrhythmias. Sinus arrhythmias include sinus tachycardia, sinus block, sinus quiescence, and sick sinus syndrome. Escape rhythm can be divided into: atrioventricular junctional escape, ventricular and atrial escape. Premature beats are mainly divided into atrial premature beat, atrioventricular junctional premature beat and ventricular premature beat. Heart conduction disorders mainly include sinus block, atrial conduction block, atrioventricular block and ventricular block. 1.2 the mechanism of arrhythmia can be divided into fast and slow two kinds, the former because of impulse conduction abnormalities, self-discipline increases, or because of sinus pathology, sinoatrial node damage and cause the self-discipline of the sinoatrial node or atrioventricular node dysfunction triggered arrhythmias induced by abnormal activities. In general, the mechanism of arrhythmias can be divided into autonomic abnormalities and conduction disturbances. 1.2.1 abnormalities of autonomic automaticity include abnormalities of sinoatrial node automatic pacing, increased automaticity of ectopic pacemaker sites, and focal re excitation. The sinoatrial node is affected by the autonomic nervous system and is also affected by the vasoactive sub
