NCT02761031

Brief Summary

This study will record patient electrocardiograms - as well as various other body signals (e.g., blood pressure, pulse wave, peripheral hemoglobin oxygen saturation) - as monitored routinely both during and immediately subsequent to surgical operations performed under general anesthesia. Through retrospective analysis of patients' heart rate variability (HRV), in concert with the other abovementioned parameters, the investigators seek to forward the development of novel mathematical models and tools for on-line detection of cardiovascular and autonomic dysfunction in the perioperative setting.

Outcome Measures

Primary Outcomes (1)

  • Heart rate variability

    The analysis of heart rate variability (HRV) has been used to assess autonomic nervous system responses to therapeutic interventions, and to quantify risk in a wide variety of both cardiac and non-cardiac disorders when combined with other diagnostic tests - though HRV analysis has seen its greatest cardiologic use in post-myocardial infarction risk stratification and in assessing risk for arrhythmic events. HRV analysis has become widespread and relatively simple to perform - however, until now, these analyses have not been performed in detail in the perioperative period.

    During and immediately subsequent to surgery performed under general anesthesia
