REVIEW
Akiko Kojima, Hiroshi Matsuura
Although various general anaesthetics affect the heart rate in clinical settings, their precise mechanisms remain to be fully elucidated. Because the heart rate is determined by automaticity of the cardiac pacemaker sinoatrial node and its regulation by autonomic nervous system, it is important to clarify the effect of anaesthetics on sinoatrial node automaticity. The spontaneous electrical activity of sinoatrial node is generated by a complex but coordinated interaction of multiple ionic currents, such as the hyperpolarisation-activated cation current (If), T-type and L-type Ca(2+) currents (ICa,T and ICa,L), Na(+)/Ca(2+) exchange current (INCX), and rapidly and slowly activating delayed rectifier K(+) currents (IKr and IKs)...

Perioperative/postoperative atrial fibrillation and flutter( POAF) is one of the common complications after pulmonary resection and the frequency is reported as 12.6% according to Society of Thoracic Surgeons general thoracic surgery database. We usually observed POAF 2~3 day after operation. While the etiology remains uncertain, the left atrial overload by the refilling from the 3rd space or systemic inflammation after surgery could raise this complication in addition to the right atrial overload following pulmonary resection and postoperative hypoxia status...

Terumoto Koike, Masanori Tsuchida
For general thoracic surgeons, perioperative management for prevention of cardiac complications is important because patients undergoing general thoracic surgery often have risk factors for cardiac disease. Sever cardiac failure should be detected and treated prior to surgery, and coronary artery may be examined in patients with risk factors for ischemic heart disease. Pulmonary resection sometimes causes right-sided heart failure due to reducing pulmonary vascular bed. In high-risk patients for rightsided heart failure, pulmonary artery pressure monitoring by right heart catheterization should be considered in addition to blood pressure and central venous pressure monitoring, and precise fluid management is required...

Brugada syndrome (BrS) is an arrhythmogenic disease reported to be one among the leading causes of cardiac death in subjects under the age of 40 years. In these patients, episodes of lethal arrhythmias may be induced by several factors or situations, and for this reason, management during anesthesia and surgery must provide some precautions and drugs restrictions. To date, it is difficult to formulate guidelines for anesthetic management of patients with BrS because of the absence of prospective studies, and there is not a definite recommendation for neither general nor regional anesthesia, and there are no large studies in merit...

BACKGROUND: The reported incidence of AF after CABG surgery varies from 20 to 40%, with the arrhythmia usually occurring between second and fourth postoperative days. Postoperative AF after CABG was associated with greater in-hospital mortality and worse survival at long-term follow-up. Therefore, intensive attention has focused on the prevention of AF in high-risk patients. Many perioperative factors have been suggested to increase the incidence of postoperative AF after conventional CABG...
