Article Synopsis
- QT/QTc prolongation can lead to torsade de pointes, and while 12-lead ECGs are commonly used for assessment, they disrupt patient care; bedside monitors with QT/QTc software have been implemented in the ICU.
- A study assessed the accuracy of QT/QTc measurements from these bedside monitors using four leads compared to standard 12-lead ECGs, involving measurements taken within 30 minutes of each other.
- The results indicated good agreement between the two methods, suggesting that bedside monitor QT/QTc readings could effectively identify at-risk patients without needing as many 12-lead ECGs, though further research is needed with larger and non-ICU patient samples.
Background: In hospitalized patients, QT/QTc (heart rate corrected) prolongation on the electrocardiogram (ECG) increases the risk of torsade de pointes. Manual measurements are time-consuming and often inaccurate. Some bedside monitors automatically and continuously measure QT/QTc; however, the agreement between computerized versus nurse-measured values has not been evaluated.
