[Research Poster] Purpose: The American Heart Association (2004) released Practice Standards for Electrocardiographic Monitoring, making recommendations for arrhythmia, myocardial ischemia and QT interval monitoring. Nurses are knowledgeable and practice arrhythmia and myocardial ischemia monitoring, however QT interval monitoring is not reliably or consistently performed. Importantly prolongation of the QT interval has been linked to an increased risk for Torsades de Pointes. The purpose of this research was to pilot an instrument tool evaluating nurse's QT interval related knowledge.

Design: Non-experimental, cross sectional survey.

Setting: Major academic university.

Sample: 33 graduate nursing students (31 female, 2 male) aged between 24-54 years (mean 34.4yrs) with 7.6 mean years of nursing experience (range 1.5-25years) completed the instrument. Majority of students worked in critical care areas (n=16 Intensive Care, 8 Coronary Care, 5 Emergency, 3 Step Down Unit, 1 Ambulatory Care). IRB approval was obtained for this research.

Methodology: Students within the adult Critical Care track Master's program where invited to complete a demographic form and complete the QT Interval Monitoring Survey; a 12 question, researcher developed instrument, assessing nurses knowledge of the AHA practice standards, QT interval monitoring and their ability to identify, measure and perform a QT interval correction. Thirteen students chose not to participate.

Results: 72.7% stated that they monitor the QT interval. No participants correct for heart rate or were able to state a correction formula. Mean knowledge test score was 6.3 out of a possible 12 (range 0 -10). 63.6% correctly marked the QT interval on an ECG example, 4 made no attempt. 60.6% measured the QT interval correctly, 8 made no attempt. 97% made no attempt to apply a QT interval correction, 1 incorrect attempt was made. Only 1 student was able to correctly identify 4 patients, out of a 12-patient group, who are most indicated for QT interval monitoring. 20/33 students were able to correctly state the measures of a small and large box on standardized ECG paper

Conclusions: 24 participants stated that they monitor the QT interval, yet no one stated that they corrected for heart rate. Participants were unable to state a QT correction formula or perform a QT interval correction. Nurse's knowledge of QT interval monitoring within this sample was poor. QT interval education is needed to improve nursing knowledge and patient safety.
