Acute coronary syndrome in Dextrocardia

Area of Science:

• Cardiology
• Medical Diagnostics

Background:

• Situs inversus with dextrocardia poses diagnostic challenges for emergency physicians, particularly in identifying acute coronary syndrome (ACS).
• While dextrocardia doesn't increase coronary artery disease risk, mirrored symptoms necessitate careful evaluation.

Observation:

• A 66-year-old male with dextrocardia presented with shortness of breath and hypotension.
• Classic ACS symptoms like chest pain may present atypically or mirrored in patients with dextrocardia.

Findings:

• A reversed electrocardiogram (ECG), including precordial and limb leads, is essential for evaluating cardiac ischemia in dextrocardia.
• Rapid application of a reversed ECG in this case led to the timely diagnosis of ST-segment elevation myocardial infarction.

Implications:

• This case highlights the importance of considering reversed ECG protocols in patients with dextrocardia presenting with concerning symptoms.
• Prompt diagnosis and intervention, facilitated by appropriate ECG interpretation, can preserve cardiac function and save lives in patients with dextrocardia and ACS.
