Patients often ask their doctors this question: I already had an ECG last time, why does the doctor want me to have an ambulatory ECG? What is the difference between this dynamic ECG and the previous one? Today, let’s discuss why doctors recommend that certain patients have an ambulatory ECG. As we all know, a usual EKG is actually done for only ten seconds or so, which means that your doctor will only be able to understand your heartbeat a dozen times, and if the arrhythmia doesn’t show up in those ten seconds or so, then he or she can’t detect the problem. But that doesn’t mean there’s nothing wrong with your heart. The primary use of an ambulatory electrocardiogram is to monitor a variety of arrhythmias, including bradycardia and tachycardia, which don’t last all day in a person, but rather are episodic in nature, where you may have been fine just a few seconds ago, and then all of a sudden develop a significant tachycardia, and then by the time you think to go to the hospital it’s gone before you get out of the house. This is well avoided by continuous and prolonged monitoring with an ambulatory electrocardiogram. When do you need to have an ambulatory ECG? 1.If you have experienced discomfort such as chest tightness, panic, dizziness, blackness in front of your eyes, etc., and a routine ECG is done but suggests that it is in the normal range, then you need to have an ambulatory ECG to monitor the changes of the ECG over a long period of time, and record the time when you experience discomfort, so that you can accurately find out what is going on with the ECG at the time of the discomfort, to discover the evidence of the clinical diagnosis. 2.Sometimes you don’t feel uncomfortable with your heart, but when you sleep at night or other times when you don’t feel anything special, your heart is quietly enduring discomfort, occasional palpitations, and stuffiness, you may need to have an ambulatory electrocardiogram (ECG) to monitor your heart’s dynamics, especially if people under 45 years old have problems with their conventional ECG, it is best to use an ambulatory ECG to look at the dynamic changes in your heart. 3. If there is a problem with the ECG after the routine ECG is done, such as premature beats, if the doctor needs to see how many episodes of premature beats there are in a day, are the episodes of premature beats in the same pattern? Are the episodes of premature beats affecting the blood supply to the heart? These are all things that should be shown on an ambulatory electrocardiogram. Clinicians can analyze and intervene based on the results of the ambulatory ECG monitoring in conjunction with the patient’s condition. 4. When myocardial ischemia is detected by routine electrocardiography, ambulatory electrocardiography is needed to show the time period, duration, frequency, degree of ischemia, and its relationship with the patient’s activities and symptoms, so as to provide a more comprehensive, practical and reliable objective basis for the diagnosis and treatment of ischemic heart disease. 5, some less easy to find heart problems, can also do dynamic ECG monitoring. Paroxysmal atrial fibrillation is one of the risks of stroke, but it is not easy to be detected and most of the patients have no obvious symptoms, the use of dynamic electrocardiogram continuous monitoring has a chance to find out, and it takes a longer time to find out this paroxysmal atrial fibrillation. 6. Some patients with heart disease need to observe whether their heart condition has improved after a period of treatment, and the same test can be used for comparison. Or compare whether the organism is not sensitive to drugs, to assist the doctor to assess in order to develop the next stage of treatment program and so on all need dynamic cardiac monitoring. 7, found in patients with hereditary arrhythmias, dynamic electrocardiography can be used to monitor the electrocardiogram for malignant conditions. 8.When considering sudden death-related arrhythmia, repeated ECG or ambulatory ECG or ultra-long range ambulatory ECG should be performed as much as possible to detect abnormal ECG conditions in time, which will help clinicians to make intervention as early as possible to protect the patients’ life safety. 9.Evaluate whether patients with heart disease need to install pacemakers or clinical pacemakers. The process of ambulatory electrocardiography covers both day and night, and can also observe neurofunctional cardiac changes. Ambulatory electrocardiography is an important medical tool to observe changes in the heart. After reading today’s content, I believe you have a more in-depth understanding of the dynamic electrocardiogram examination, whether you need to perform dynamic electrocardiogram examination suggests that you still listen to your doctor’s words, for your disease diagnosis and treatment will be more helpful!
