I feel sick to my stomach. I need to do an electrocardiogram.
Toothache, I need to do an electrocardiogram first.
Diarrhea, it is recommended to do an electrocardiogram.
My left hand is numb. Let’s do an electrocardiogram first.
Teachers in the electrocardiogram room often hear "complaints" from those being examined: Did the doctor make a mistake? I don’t feel sick about my heart, why do I need an electrocardiogram? Faced with the above common confusion among everyone, the editor must do some popular science.
Heart sound recording - electrocardiogram
Electrocardiogram (ECG) is a technology that uses an electrocardiogram machine to record the electrical activity changes produced by the heart in each cardiac cycle from the body surface.
The moment before each heart beat, it will emit a set of very regular weak electrocardiographic currents. The currents are transmitted to the surface of the human body, and after being received and converted, an electrocardiogram pattern is formed. And by understanding these graphics, you can understand the "voice of the heart."
Understand the graphics and decipher the voice
The electrocardiogram examination is very simple and can be completed with only 6 electrode balls and 4 electrode clips. However, it is also the most sensitive examination method. Doctors can learn from your ECG waveform how much your heartbeat is, whether your heart rhythm is regular, whether you have myocardial ischemia or arrhythmia and other conditions.
ECG examination can be performed at any time, and diet will not affect the examination results. We only need to wear loose clothes during the examination, cooperate with the doctor to expose the skin at the corresponding location, keep the limbs relaxed, have a calm mind, do not be nervous or excited, and maintain calm breathing.
Myocardial infarction
Doctors can observe the location and severity of myocardial infarction through electrocardiogram. However, myocardial infarction is sometimes extremely cunning. Not only does it not have its most typical clinical symptom - chest pain, but it develops various atypical symptoms, such as stomach pain , toothache , shoulder pain, and back pain.
If the above-mentioned pain occurs due to this, the doctor will recommend the patient to undergo an electrocardiogram at his or her discretion. Not only is this not an "excessive examination", but it is the optimal choice to "fully weigh the pros and cons."
Diarrhea
Patients with persistent diarrhea will have electrolyte imbalance in severe cases, especially hypokalemia, which can be clearly reflected by electrocardiogram examination.
Patients who are taking related drugs
Doctors use electrocardiogram to monitor the impact or effect on the heart during the medication, such as digitalis, codalone, etc., so as to adjust the dosage of the medication in a timely manner.
For patients equipped with pacemaker and other cardiac implantable devices
use electrocardiogram to check whether the device is working properly.
Pregnant women
During pregnancy, as the gestational age increases, the burden on the heart will also increase. Regular electrocardiogram examinations can help doctors understand whether pregnant women have any abnormal changes, such as sinus tachycardia , arrhythmia and other cardiac conditions.
In addition, if the electrocardiogram indicates abnormalities, doctors often recommend cardiac examinations such as 24-hour dynamic electrocardiogram or cardiac color ultrasound. An electrocardiogram can only reflect your heart rhythm at that moment, and sometimes cannot capture intermittent arrhythmias.
and dynamic electrocardiogram monitors the rhythmic movement of the heart within 24 hours, which can further understand whether there is arrhythmia .The items of cardiac ultrasound examination are even more different. It mainly observes the structure, size, movement, function, etc. of the heart, and then comprehensively judges the function of the heart to determine whether there is organic heart disease.
The editor has reached this point. I believe that everyone has a better understanding of "Decrypting Voices", has more trust in clinicians, and will no longer complain about undergoing electrocardiogram examinations!
