Key Points 1. Cardiac patients presenting for emergency noncardiac surgery have higher risk for perioperative morbidity and mortality. Emergency surgeries are associated with two to five times the risk of major adverse cardiac events compared with elective procedures. Preoperative evaluation…
Key Points 1. Tachyarrhythmias result from one of three mechanisms (reentry, automaticity, and triggered activity), with reentry being the mechanism most commonly treated in the electrophysiology (EP) laboratory. 2. Anesthetic agents influence cardiac conduction and arrhythmogenesis and can adversely affect…
Key Points 1. Intraoperative hemodynamic instability may be associated with increased cardiovascular complications and represents one of the most common findings associated with mortality. 2. Phenylephrine can be used for the treatment of intraoperative hypotension through an increase in stroke…
