Using the 12-lead ECG to assess acute coronary patients
1St Georges Hospital, University of London.
Insights
Acute coronary syndromes (ACS) are diagnosed using electrocardiograms (ECG). Advanced ECG interpretation by nurses aids in early detection and management of myocardial infarction (MI) and other ACS conditions.
Area of Science:
- Cardiology
- Medical Diagnostics
Background:
- Acute coronary syndromes (ACS) result from unstable plaque rupture in coronary arteries.
- ACS classifications include unstable angina, non-ST elevation myocardial infarction (MI), and ST elevation MI.
- Electrocardiograms (ECG) are vital for assessing myocardial ischemia, injury, and infarction in ACS patients.
Purpose of the Study:
- To highlight the significance of ECG in diagnosing ACS.
- To emphasize the extended diagnostic capabilities of ECG for right ventricular and posterior wall assessments.
- To underscore the role of critical care nurses in ACS management through ECG interpretation.
Main Methods:
- Review of ECG's role in ACS assessment.
- Discussion of extended 12-lead ECG applications.
- Emphasis on critical care nursing skills in ECG interpretation.
Main Results:
- ECG effectively identifies location and extent of myocardial damage in ACS.
- Extended ECG views provide crucial data on right ventricular and posterior wall involvement.
- Skilled nurses enhance early ACS detection and treatment decisions.
Conclusions:
- ECG is indispensable for ACS diagnosis and management strategy.
- Advanced ECG interpretation, including extended views, improves diagnostic accuracy.
- Critical care nurses equipped with ECG skills are essential for timely and effective ACS patient care.
Abstract:
Acute coronary syndromes (ACS) are characterized by the rupture of unstable plaque within coronary arteries. Depending on the extent of the ensuing occlusion and myocardial damage, ACS can be classified as unstable angina, non-ST elevation myocardial infarction (MI) and ST elevation MI. The electrocardiogram (ECG) is an invaluable tool in the assessment of patients with ACS. It provides evidence for the location of myocardial ischaemia, injury and infarction and is a crucial factor in the decision to administer thrombolytic agents and other management strategies. The 12-lead ECG is limited to a view of the left ventricle, however it can be extended to provide additional information about the right ventricular and posterior walls. Critical care nurses with ECG skills can contribute to the early detection and management of patients with ACS.

Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
