BEVACQUA, Raúl J.. Chronic ST-segment monitoring via the intracardiac electrogram for implantable cardiac device. Insuf. card. [online]. 2013, vol.8, n.1, pp.31-40. ISSN 1852-3862.

The placement of an implantable cardiac device (ICD), either a pacemaker, an implantable cardioverter defibrillator or a device for cardiac resynchronization therapy is an increasingly common practice in heart failure patients. Within these ICD technological advances is the possibility of monitoring ST segment changes. Continuous ST-segment monitoring via intracardiac electrogram is predicated on the understanding that acute ST changes are frequently correlated with clinically significant coronary events. ST-segment monitoring via Holter ECGs have proven useful for patients who are asymptomatic with coronary syndromes which include coronary artery disease (CAD), acute myocardial infarction, unstable angina, as well as symptomatic patients with a nondiagnostic ECG (no-ST elevation) from standard diagnostic electrocardiograms. Concluding that for patients with CAD, especially post-myocardial infarction, ST segment monitoring can play an important role.
