Clinical Case Report
This educational clinical case examines ECG artifacts and their clinical implications, focusing on the critical importance of acquisition parameters and filtering settings in electrocardiographic signal processing. The case demonstrates how filtering artifacts can lead to diagnostic misinterpretations and highlights the need for standardization in electrocardiography.
The article presents a case of a 25-year-old endurance athlete undergoing medical certification for military service, whose ECG showed abnormal biphasic T waves in the right precordial leads, emphasizing the potential pitfalls in clinical interpretation when technical factors are not properly considered.
