A Case of New Electrocardiographic Changes During a Routine Health Checkup Requiring Urgent Cardiologist Consultation

Acute coronary syndrome (ACS) is a clinical condition associated with a high mortality rate, necessitating prompt and accurate diagnosis and immediate treatment. We present a case in which ACS was accurately identified during a routine health checkup, leading to an urgent consultation with a cardiologist. In this case, the electrocardiogram (ECG) revealed new ST-T changes and abnormal Q waves, contrasting with the results of a routine ECG conducted during a health checkup one year prior. For an effective diagnosis of ACS, it is crucial to compare the current ECG with a previous ECG obtained during routine health checkups. In conclusion, during medical health checkups, ACS, a potentially life-threatening condition, should be considered in individuals with risk factors or symptoms, and any new ECG changes, particularly ST-T alterations, should prompt immediate referral to cardiologists.
