If the ECG of the induction physical examination is not satisfactory, first of all, it is necessary to clarify whether there is organic heart disease. It is recommended to give plate exercise test, cardiac ultrasound and other examinations, and if necessary, coronary artery imaging to clarify whether there is organic lesion. If organic changes are present, systemic related treatment needs to be given. In addition, induction ECG failure may include a variety of conditions that can present with abnormal ECG such as arrhythmia. For arrhythmia, it can be seen in normal people, so if arrhythmia is present, it can still pass the physical examination after systematic examination without organic pathology. In addition, people with obesity and those who are too thin may have conditions such as high left ventricular voltage on the ECG, which is not a diagnostic criterion for specific hypertension and requires a comprehensive judgment combined with blood pressure and cardiac ultrasound to evaluate the presence of cardiac hypertrophy and other conditions.
