If a patient currently has sinus rhythm ST segment changes, the need for treatment also needs to be considered in the context of the patient’s actual current clinical symptoms and what form of ST segment changes are currently present. For example, sinus rhythm is a normal rhythm, which means that the current heart rate is paced by the sinus node, while ST-segment changes, if the current elevation is arch-back upward, are highly considered to be an acute ST-segment elevation myocardial infarction, and such patients should undergo urgent coronary intervention. If the patient currently has only mild ST-segment depression, it may be due to coronary atherosclerotic heart disease. If the patient is not obviously symptomatic, he can combine oral aspirin, atorvastatin, metoprolol and other drugs for improvement. In other patients, there are non-specific ST-segment changes, that is, without any significance, in which case treatment is often not required.
