BACKGROUND Accurate measurements for determining cardiac index can be obtained while patients are supine in bed at various backrest elevations. It is not clear if these measurements are accurate when patients are in a bedside chair. OBJECTIVE To determine if cardiac index based on measurements obtained with the patient in a chair is similar to cardiac index based on measurements obtained with...

Perioperative cardiac morbidity is the leading cause of death following the administration of general anesthesia. With the aging of the population, the number of patients at significant cardiac risk for noncardiac surgical procedures is expected approximately to double over the next 30 years. Assessing cardiac risk will assume increasing importance in surgical decisions. Historical predictors, ...

Introduction Robotic-assisted surgery is increasingly being used in various surgical specialities to decrease blood loss, surgical stress and to improve cosmesis. Over past two decades it has become popular in cardiac surgery as well. Various cardiac surgical procedures like valve surgery, coronary artery surgery and congenital repair procedures can be done with robotic help. Anaesthetic manage...

BACKGROUND Cardiac perforation is a recognized complication of catheter ablation procedures, most commonly encountered during ablation of atrial fibrillation. The study aims to investigate the incidence, management, and hospital outcomes of cardiac perforation complicating catheter ablation for ventricular arrhythmias. METHODS AND RESULTS Consecutive patients undergoing catheter ablation for ...

OBJECTIVE We studied the variable effects of norepinephrine infusion on cardiac output in postoperative cardiac surgical patients in whom norepinephrine increased mean arterial pressure. We hypothesized that the directional change in cardiac output would be determined by baseline cardiac function, as quantified by stroke volume variation, and the subsequent changes in mean systemic filling pres...

t-wave oversensing occurs when the counter starts giving dual beeps for every cardiac cycle instead of one. this usually happens when the monitoring lead displays a tall t wave, which is also sharp. r wave sensing algorithms of the devices do not sense t wave because the slow rate of the t wave is much less than that of the r wave. but the slow rate of t waves may change with time and also beca...
