Every patient is different and our ECG machines use world-class standards to enhance reading accuracy and diagnostics. The 2009 AHA/ACCF/HRS recommendations have new ST elevation myocardial infarction (STEMI) criteria that now depend on both age and gender. In addition, the patient’s race, medication history, etc. will also affect the results of an ECG interpretation. The physiological structure of newborns and infants is slightly different from that of adults - the right ventricle is larger and thicker than the left ventricle. Therefore, a special algorithm for paediatric use is required to provide more reliable and accurate diagnoses.
