Abstract

Cardiovascular disease is one of the most prevalent causes of death which has a high mortality rate. If identified early and treated appropriately, the mortality in patients with cardiovascular disease can be hugely reduced. For several decades, 12-Lead ECG has been the standard technique used to identify ischemia, and recent studies have shown that intracardiac electrogram has many benefits over external monitoring such as holter. ST Monitoring feature has been added to St. Jude Medical intracardiac cardioverter defibrillators (ICD) to leverage the ECG technology for identifying cardiovascular disease. This algorithm monitors the intracardiac electrogram to detect and report patterns which could be related to ischemic events. This feature is expected to enhance the process of identifying ischemia and infarction, and provides long-term management of the disease.

In order to support the new implantable devices with ST Monitoring capability, the programmer software was updated to support this new feature in the device. This thesis discusses the work on the programmer. Chapter 1 begins with a background of how monitoring technology in an implantable device can benefit the patients facing high risk of myocardial infarction. Chapter 2 states the objective for the work on the programmer. Chapter 3 describes the implementation and the application of this feature. Conclusion and future development are discussed in Chapter 5.
