Background:
The case of 30 years-old patient with recently diagnosed dextrocardia is discussed hererin.

Material and methods:
Dextrocardia, a specific anomaly of heart position in the chest, usually associated with situs inversus and sometimes by Karteneger’s syndrome was diagnosed in the patient by careful physical examination proven by electrocardiography and imaging.

Results:
Specific ECG changes were crucial to recognize the syndrome. The patient presented total situs inversus in physical examination. The case is a good exemplification of frequent dextrocardia oversight, since it has not been found during previous 30 years by medical professionals, including both pediatrician and occupational medicine specialist.

Conclusions:
The attention should be always turned to make a proper diagnosis because it allows to recognize properly additional diseases as well as avoid misdiagnosis in future.
