title: [How to treat arrhythmias in thoracic surgery].
abstract: After major noncardiac thoracic operations, various types of arrhythmia would occur. Particularly atrial fibrillation (Af), have remained one of the most frequent complications. In the literatures, risk factors for post operative Af have identified age, male, extent of pulmonary resection and mediastinal lymph node dissection. When we would meet the patients complicated with arrhythmia, the etiology of it must be identified and treated before operations. If accidental arrhythmia occurred during or after operations, the etiology of arrhythmia as hypoxia, hypercapnea, electrolyte disorder, overhydration and cardiac ischemia would be checked and cleared at first. Then appropriate drugs should be considered to use due to the type of arrhythmia. In supraventricular tachyarrhythmia, especially Af, landiolol and verapamil would be effective for the rate control and disopyramide and procaineamide for the defibrillation. Lidocaine and propranolol would be an appropriate choice for ventricular tachyarrhythmia during operations. For ventricular tachyarrhythmia related with acute myocardial infarction, lidocaine and mexiletine would be proper. In bradyarrhythmias a temporary pacing should be the first choice for urgent therapy. A prompt assessment and an adequate therapy must be mandatory for the arrhythmias after major noncardiac thoracic operations.
