The data displayed by the electrocardiograph is okay, does it mean that the heart is okay?
After reading this title, many people will surely have false data displayed on the electrocardiograph? But the results of conventional electrocardiograph inspection sometimes "lie". Let's follow the editor of the electroencephalograph to find out.
Electrocardiogram is a technique that uses an electrocardiograph to record the changes in electrical activity generated by the heart during each cardiac cycle. It is the simplest, fastest, and most economical way to check whether the heart's electrical activity is normal. The diagnosis of acute myocardial infarction has important clinical value. At the same time, other pathological changes in the system other than the heart can be prompted by ECG, such as pulmonary embolism, hyperkalemia, and hyperthyroidism. However, conventional ECG is an immediate and short examination, and the result is to reflect the ECG condition at the time of examination. Therefore, in view of the arrhythmia phenomenon, if the electroencephalogram machine is under examination, the heart does not have an arrhythmia attack, it cannot be detected.
In addition, the conventional electrocardiogram is not very sensitive and specific for the diagnosis of structural heart disease. Partial ischemic heart disease, especially non-acute ischemia, may also have no special abnormalities in the electrocardiogram. Therefore, some patients have electrocardiograms No obvious abnormalities were found on the examination, but she did have organic heart disease.
It is recommended that if the ordinary ECG is normal, but in daily life, symptoms of suspected heart disease such as palpitation, chest tightness, and chest pain occur from time to time, especially if the above symptoms are related to the amount of exercise and emotional excitement, you can do a treadmill exercise test or dynamic ECG to confirm Heart problems.
Of course, the heart examination is much more than that. In addition to the treadmill exercise test and dynamic ECG observation, the EEG machine also has some auxiliary examinations, such as the dynamic changes of myocardial enzyme spectrum, coronary CT, and coronary angiography.
