#CARDIAC MONITOR THAT CONTIUSLY MONITY ST ELEVATION SKIN#

You may use alcohol if the skin is oily, but be aware that alcohol can dry the skin and increase electrical resistance. At each electrode site, clean the patient’s skin with soap and water, rubbing the area slightly with a washcloth or gauze pad.To help ensure accurate monitoring, take these steps when placing electrodes: helping predict failure to wean from mechanical ventilation.Ĭonsistent placement of electrodes and leads is crucial for accurate monitoring, because improperly placed electrodes can contribute to false alarms.helping to differentiate cardiac and noncardiac chest pain.detecting abrupt closure and reocclusion of the affected vessel after PCI.

detecting perioperative ischemia in patients with a cardiac history who are undergoing other surgical procedures.Other uses of continuous ST-segment monitoring include: It also may benefit patients experiencing coronary vasospasm or ischemia related to hypoxia, as well as those recovering in the intensive care unit after cardiac surgery and other procedures. Generalized ST-segment deviation across several leads rather than isolated to a group of leads suggests postoperative pericarditis.Ĭontinuous ST-segment monitoring may reveal the extent of tissue injury in patients undergoing transmyocardial laser revascularization. In patients who’ve undergone cardiac surgery, continuous ST-segment monitoring yields information about graft patency and the occurrence of perioperative MI. For instance, it helps them assess patency of the infarct-related vessel after thrombolytic therapy and detects recurrent ischemic episodes after a PCI or infarct extension. Early identification of ischemic events gives caregivers the opportunity to initiate early reperfusion and take other actions to help keep the involved artery patent. In the ED, these patients initially may have a nondiagnostic ECG, but continuous ST-segment monitoring shows that a certain percentage have ST-segment changes within minutes to hours.Ĭontinuous ST-segment monitoring also contributes to improved survival rates in AMI patients. Detecting myocardial ischemia early allows the healthcare team to reverse ischemia and thus prevent or interrupt myocardial cell death. The best candidates for continuous ST-segment monitoring are patients with ACS who have unstable angina or acute myocardial infarction (AMI) with or without ST-segment elevation. The information in this article reflects that standard. In 2004, the American Heart Association (AHA) published a standard that provides guidelines for continuous ST-segment monitoring to help improve outcomes for patients with ischemia. Continuous ST-segment monitoring, in contrast, reveals ischemic events over time, providing a more accurate and complete picture of the patient’s myocardial physiology. The standard 12-lead ECG captures only a small snapshot (approximately 10 seconds) of the myocardial electrical cycle-a period too brief to show the waxing and waning of ST segments. By revealing changes in the ST segment (the component that immediately follows the QRS complex on the ECG), continuous ST-segment monitoring can reveal both the severity and duration of ischemia, giving early warning of ischemic events. About 80% to 90% of ECG-detected ischemic episodes are clinically silent.

Jenkins and other patients with acute coronary syndrome (ACS) might easily go undetected until irreversible myocardial damage occurs. Without continuous ST-segment monitoring, the silent ischemia suffered by Mrs. Within minutes, she’s taken to the catheterization lab for a percutaneous coronary intervention (PCI). A repeat 12-lead ECG confirms anterior-wall ischemia. Jenkins says she’s short of breath and her chest feels tight again. She’s started on supplemental oxygen at 4 L/minute and connected to a cardiac monitor blood is drawn for cardiac biomarker testing.Īpproximately 45 minutes later, the ST-segment alarm on her cardiac monitor rings, and the nurse detects ST-segment elevation in the anterior leads (V2, V3, and V4). An electrocardiogram (ECG) recorded within 6 minutes of her arrival shows normal ST segments in the meantime, she reports that her chest discomfort has subsided. Anita Jenkins, age 54, arrives at the emergency department (ED) complaining of shortness of breath and chest tightness.
