Anaesthetic management of a patient with sick sinus syndrome for exploratory laparotomy
AbstractSick sinus syndrome is a generalised abnormality of cardiac impulse formation that may be caused either by an intrinsic disease of the sinus node, which makes it unable to perform its pacemaking function, or by extrinsic factors. It commonly affects elderly persons. While the syndrome can have many causes, it usually is idiopathic. Abnormalities encompassed by this syndrome include sinus bradycardia, sinus arrest or exit block, combinations of sinoatrial and atrioventricular nodal conduction disturbances and atrial tachyarrhythmias. Diagnosis of sick sinus syndrome can be difficult because of its nonspecific symptoms and elusive findings on an electrocardiogram or a Holter monitor. Here, we present the perioperative management of an elderly patient with sick sinus syndrome with seminoma of undescended testis posted for exploratory laparotomy.
