12-Lead EKG is Upgraded
While limb and chest leads have been traditional components of the 12-lead ECG, it has long been recognized that additional electrodes can provide information that is poorly or not seen at all on a traditional 12-lead ECG, says Joris van den Hurk, vice president of cardiology programs for Philips Healthcare.
The standard 12-lead ECG has a blind spot on the right side of the patient's chest that limits the ability to detect right ventricular myocardial infarction. (MI), which Philips may not have detected with a 12-lead ECG, says Debbie Heinecke, RN, manager of non-invasive cardiology at Blessing Hospital in Quincy, IL, an early user of the new technology. Philips' new DXL Algorithm technology addresses this issue by using electrodes placed on the right side to provide incremental capabilities not available with previous programs.
Gender-specific Criteria for Women's Heart Health
Women often present cardiac symptoms differently from men and have a higher mortality rate from cardiovascular disease.
Confirming Philips' commitment to developing technologies for women's health, the DXL algorithm applies new gender, age and lead-specific STEMI (ST-segment Elevation Myocardial Infarction) criteria to detect acute MI in women as well as men.
A widespread pattern of ST depression often reflects global ischemia due to left main coronary obstruction, multi-vessel obstructions, or microvascular disease, which is more prevalent in women.
The DXL Algorithm incorporates new criteria for these conditions and provides a "Critical Value of Global Ischemia" to highlight when prompt intervention may be needed. The new algorithm also builds upon Philips' long use of gender and age-specific criteria, left ventricular hypertrophy and prolonged QT interval.
Philips PageWriter TC70 Cardiograph provides innovative platform for new DXL Algorithm
In addition, the PageWriter TC70 cardiograph not only incorporates the new DXL Algorithm, but also improves workflow and enables faster clinical decision-making making.
ECG reports are quickly taken and transferred to the TraceMasterVue ECG management system with the click of a single button. Bedside decision-making is enhanced with the automatic retrieval of the previous ECG, allowing for immediate clinical serial comparison.
The new PageWriter includes technologies that are especially useful in the Emergency Room, where ECG reports can highlight test results that may warrant immediate clinical attention. When used with the DXL 16-Lead Algorithm, the PageWriter TC70 provides a powerful tool to reduce a hospital's door-to-balloon times.
