Qt Monitoring In The Icu: A Benchmark Project, Jeffrey S. Woodward Apr 2020

Qt Monitoring In The Icu: A Benchmark Project, Jeffrey S. Woodward

MSN Capstone Projects

In adult Intensive Care Unit (ICU) patients, does QT/QTc monitoring compared to no QT/QTc monitoring affect mortality or ventricular tachyarrhythmia rates during their ICU stay? Not monitoring changes in the QT interval can lead to poor outcomes since mortality rates are higher in patients with arrhythmias (Uvelin, Pejakovic, & Mijatovic, 2017). Approximately 300,000 sudden cardiac deaths occur in the United States each year with an estimated 15,000 because of a lethal ventricular tachyarrhythmia rhythm called Torsades de Pointes (TdP) that occurs when a QT interval is prolonged (Dave, Bessette, & Setnik, 2017). Some risk factors for developing prolonged QT intervals …
