The pivotal role of the ECG is to examine cardiac function and can aid in the diagnosis of cardiac diseases such as myocardial infarction or myocardial ischemia. At the same time, the efficacy of drugs such as antiarrhythmics can be judged, but also whether thrombolysis is successful.
Physicians often recommend an ECG if they experience symptoms of cardiac discomfort during the usual hours. However, it is not clear in many patients what the ECG specifically has. So what is the role of the ECG?
1. Examination of cardiac function
ECG can reflect whether there is an abnormal response in cardiac function. The ST segment and T wave of the electrocardiogram were used to determine whether the myocardium had insufficient blood supply and similar injury symptoms, and to determine the atrial and ventricular structure, so that the arrhythmia and the tachycardia and atrial fibrillation could be definitely diagnosed, which could provide a key diagnostic basis for cardiac diseases such as myocardial infarction.
2. Judging drug efficacy
After taking antiarrhythmic and Antimyocardial ischemic drugs for a period of time, it needs to be reviewed by electrocardiogram, so that the performance of drug efficacy can be judged, which can be used as the basis for changing the type and dosage of drugs, and ensure that the drug treatment plays the greatest role.
3. Other roles
Patients with myocardial infarction can be followed by electrocardiography after thrombolysis, mainly to determine whether thrombolysis is successful and whether recanalization is necessary. In addition, it can also be used to diagnose some systemic diseases.
