Abstract
In many cases, failure to perform an electrocardiogram according to established standards can lead to incorrect diagnosis. When this error involves a disease that can result in sudden death such as Brugada syndrome, diagnostic procedures are not without risk for the patient.A 20year-old man visited his family doctor for atypical chest pain some time before. Electrocardiography (ECG) showed sinus rhythm of 47bpm with striking ST-elevation in V1–V3 suggestive of the Brugada pattern. Sometimes, the different low-frequency components of the ECG, such as the ST segment, may be distorted by high cutoff filters resulting in diagnostic errors [Am J Cardiol 2012;110:318–320]. Faced with an apparent Brugada syndrome pattern on ECG, clinicians should ensure the recording was correctly made.
