R wave incremental adverse pathological aspects consider the possibility of coronary heart disease, myocardial infarction, lung disease; physiological factors consider excessive fatigue, mental stress, sleep deprivation and so on. 1. Pathological factors: for patients with combined hypertension, hyperglycemia and hyperlipidemia, consider the possibility of coronary heart disease and myocardial infarction. Comprehensive diagnosis of electrocardiogram, cardiac enzymes, coronary artery imaging is recommended. Patients presenting with pulmonary diseases such as pneumothorax, severe pleural adhesions, etc., may also present with poor D-wave progression. 2. Physiological factors: most often seen in excessive fatigue, mental stress, lack of sleep, etc. It is recommended to give standardized treatment, as well as lifestyle changes, and pay attention to dynamic monitoring of ECG changes. Normal R wave in the chest lead from V1 to V6 should be gradually rising, S wave gradually becoming shallow, R/S ratio gradually increasing. Poor ECG R-wave progression means that the R-wave on the ECG is in the V1~V6 leads and does not show a gradual increase in the degree of the R-wave. If the patient usually does not have any other discomfort, there is no need to worry too much, pay attention to regular physical examination and follow-up observation. If the patient is suffering from serious cardiac diseases that lead to R-wave dysplasia, he should be hospitalized in time for observation and dynamic monitoring of electrocardiogram and cardiac enzymes.
