There was a patient who spoke very interestingly today. He is not very old, 62 years old, has a good lifestyle, and has quit smoking and drinking for more than ten years. However, I have been taking antihypertensive drugs for more than ten years with high blood pressure. He is a gardener, because he needs to water the greenery, he has been up very early in the last few days, and he has got up at two or three in the morning. Also in the last few days, I started to experience the sensation of ventilating my heart, which lasted for more than an hour for a long time, and a short ten minutes.

I asked the patient if he had any feelings in his heart when climbing the stairs, and he replied: I got up by the elevator! Also a very real comrade...

Then I asked him to do an electrocardiogram, which showed that there was nothing abnormal, so I asked him to do another stress ecg. He asked: Why do I have to do an ECG twice? Is there any difference? This is also a question that many patients are curious about.

It's like this: Many patients with coronary heart disease have a normal ECG when they are calm. In other words, when they are calm, the blood supply of the heart can meet their own needs. During a certain intensity of exercise, the heart's blood supply is insufficient, and the ECG will be An electrocardiogram with ischemia-like changes appears, and even the patient has symptoms similar to the disease at the same time. Therefore, although the ECG is a very important diagnostic method, only a static ECG can not rule out coronary heart disease if it is normal!

So what is stress ecg? As the name suggests, it is when you exercise (there are programs such as stepping, cycling, running, etc., there are standard exercise programs, exercise end points, etc.) to give you an electrocardiogram, mainly to observe the changes in the electrocardiogram during exercise. Then through exercise, you can cause your underlying myocardial blood supply shortage!

If the stress ecg is not abnormal, the possibility and risk of coronary heart disease is greatly reduced.
