Electrocardiograms in Critical Care Cardiology: Is it Acute Coronary Syndrome?

Area of Science:

• Cardiology
• Critical Care Medicine
• Electrocardiography

Background:

• Electrocardiogram (ECG) interpretation is crucial in critical care.
• Distinguishing critical illness-related ECG changes from acute coronary syndrome (ACS) poses a diagnostic challenge for clinicians.

Observation:

• Presents three clinical cases where patients with critical illness exhibit ECG findings that resemble ACS.
• Details the specific ECG characteristics, clinical presentations, and underlying causes for each case.

Findings:

• Illustrates how non-ischemic conditions can manifest with ST-segment and T-wave abnormalities on ECG.
• Highlights key differentiating features between critical illness-induced ECG changes and true ACS.

Implications:

• Enhances physician ability to accurately diagnose ECG abnormalities in critically ill patients.
• Aids in avoiding unnecessary interventions for suspected ACS when findings are due to critical illness.
• Improves diagnostic accuracy and patient management in critical care settings.
