Clinical application of electrocardiogram

Time : 2022-12-02

The most important function of the electrocardiogram is to take an electrocardiogram when we are feeling uncomfortable, to provide very important objective evidence for us to rule out heart disease, whether it is myocardial ischemia or arrhythmia, and provide a basis for our next treatment.

Electrocardiogram can assist in the diagnosis of myocardial ischemia, arrhythmia, heart size, lung disease, pulmonary embolism, high voltage, increased cardiac load, pneumothorax and other diseases. Most importantly, myocardial infarction can be clearly diagnosed. site of infarction.

The significance of the electrocardiogram lies in dynamic observation, especially when judging myocardial ischemia, we need to observe the dynamic evolution of the electrocardiogram, that is, we have an electrocardiogram when we are good, and an electrocardiogram when we are uncomfortable, and compare the changes. Significant, in order to diagnose myocardial ischemia.

Electrocardiogram is a very commonly used and very important tool in hospitals.

It is easy to operate, affordable, and can be judged quickly, especially in the diagnosis of acute myocardial infarction and arrhythmia. It is of great value. To save time for our rescue of acute myocardial infarction, it is an indispensable examination for cardiologists, or hospitals.

For example, if we diagnose an acute myocardial infarction, we need to meet 2 of 3 conditions to make a diagnosis:

1.Typical symptoms of persistent angina pectoris; 2. Electrocardiogram showing myocardial infarction; 3. Elevated myocardial enzymes. However, when acute myocardial infarction occurs, the patient must have symptoms before seeing a doctor, but this is only a condition, and it is a subjective condition, that is, the patient's self-perception, and errors may occur. We cannot just diagnose acute myocardial infarction based on the patient's symptoms and persistent chest pain, and give the patient thrombolysis or stent. But with acute myocardial infarction, every second counts, and we dare not waste a single minute. At this time, the help of electrocardiogram is needed. If the electrocardiogram shows ST-segment arched elevation or T wave peak, we can diagnose acute myocardial infarction, and we can perform thrombolysis or angiography. The detection of myocardial enzymes generally takes 30-40 minutes. At this time, we cannot wait for myocardial enzymes, waiting is a waste of time. Therefore, in the rescue process of acute myocardial infarction, the electrocardiogram has played the greatest value. Therefore, if the electrocardiogram is used well at critical moments, it can really save lives!
