Brief description of study

What is the purpose of this study?
The purpose of this study is to test the hypothesis that skin sympathetic nerve activity (SKNA) can be used as a biomarker for physiological events including predicting neurological recovery during supportive care for cardiac arrest, and to risk stratify patients for recurrence of atrial fibrillation (AF) following catheter ablation.
 
THIS STUDY IS ENROLLING BY INVITATION ONLY - Potential research subjects will be recruited from the intensive care unit at IU Health Methodist Hospital or from the outpatient cardiology clinic at the Krannert Institute of Cardiology.

Detailed description of study

What will happen during the study?

Skin sympathetic nerve activity (SKNA) recordings will be obtained from ECG electrodes placed on the skin.  Recordings will be obtained from patients who are either undergoing supportive care for cardiac arrest (A); or receiving catheter ablation therapy for AF (B).  The recordings are obtained non-invasively during routine care in a prospective study.  Patients will not be assigned to any intervention.
