Ventricular tachycardia (VT) is a life-threatening, fast heart rhythm that starts in the lower chambers of the heart (the ventricles). This fast heartbeat is caused by abnormal electrical pathways located in the heart tissue. A standard procedure called a catheter ablation has been used for several years to help correct these abnormal pathways and, in some cases, improve or even eliminate the ventricular tachycardia. During a VT ablation it is routine to monitor your vital signs (blood pressure, heart rate, and oxygen saturation in your blood). If you choose to participate in this study we will also monitor your cerebral oximetry, the amount of blood flow and oxygen saturation to your brain during the ablation. By doing this study, we hope to have a better understanding of patients' blood and oxygen flow to their brain during an episode of Ventricular Tachycardia (VT).
Study Type
OBSERVATIONAL
Enrollment
11
Participants will be asked questions relating to pre-procedure items and be asked to complete an MMSE. Subjects receive standard of care surgery. Data collected from procedures before, during and after surgery.
University of Kansas Medical center
Kansas City, Kansas, United States
Identify clinical, EKG and EGM characteristics of hemodynamically unstable VT
The investigator will be evaluating the relationship of the oxygenation level of the brain during a Ventricular Tachycardia ablation.
Time frame: Change from Baseline to 24-48 hours after surgery
MMSE to determine cerebral function before and after VT ablation
The use of the Mini-Mental Status Exam prior to the ablation will serve as a reference point and will be repeated 24 hours post exam.
Time frame: 24 hours after surgery
