By following the guidelines andd recommendations presented in this conclussive guidee, clinicians, technichines, biomedical conterners, and their healthcare professionals can ensure that their ECG systems are configulie to capture the full spectrem of cardicac electrical activity necesary for create diagnosis andd monitoring. Thi attention to technical detail, combinad witch clicical expertise and patient- centered care, forms thee foredation of highquality cardicardivasculair medicine.
