Official title
Ventricular Fibrillation and Electrocardiographic Rhythm vs Echocardiographic Rhythm During Cardiac Arrest
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to measure survival rates associated with patients presenting in cardiac arrest based on their electrocardiographic rhythm and their echocardiographic rhythm. Electrocardiographic rhythm is defined as the rhythm on the ECG and echocardiographic rhythm is the rhythm visualized on bedside ultrasound. Specifically, we will categorize patients based on identical rhythms and dichotomous rhythms with an interest in outcomes in the patient group where their echocardiographic and electrographic rhythms do not match. This is important as current ACLS protocols use electrocardiographic rhythms to determine therapy but limited research implies that therapeutic decisions based on echocardiographic rhythm may produce increased survival. This study will occur during emergency department resuscitation of patients presenting in cardiac arrest. Patients presenting to the emergency department after cardiac arrest will undergo standard resuscitation based on ACLS protocols. Ultrasound imaging will be performed as soon as possible after the patient arrives and digitally recorded, as is currently the standard of care at the institute. Simultaneous recording of the ECG rhythm strip will occur as well. This will be repeated for as many pauses in CPR as is warranted. Each site will record data based on the Utstein nomenclature including patient demographics, arrest details and survival outcomes. Ultrasound images and ECG recordings will be de-identified and submitted to a central database. Data will be uploaded into a centralized database. Statistical analysis will analyze outcomes based on echocardiographic and sonographic findings. Our aim is to measure the survival benefit of treating out of hospital cardiac arrest using echocardiographic rhythm instead of electrocardiographic rhythm.
