心电图对某些心脏病的诊断有着特殊的重要意义。例如心肌梗塞,它有独特的圈型变化,据此可以对心肌梗塞定位。又如心律不齐,可以从心电图精确地了解紊乱的异位起搏点等。但是心电图记录不出解剖上的变化。有些病人临床上已经诊断出风心病、二尖瓣狭窄,杂音很明显,但心电图还可能正常。因此心电图正常却不能肯定病人没有心脏病。反之,由于一些原因引起心电改变,出现不正常图型,并非就是心脏病。有些病已经痊愈,但心电图可能遗留不正常。有些心电图虽有改变,但临床参考意义不具体。因此绝不能认为有了心电图就可以代替临床或其它检查。关于心电图的实用价值,根据临床的大量实践,大致可以分为三大类。1.有决定诊断的价值。2.对诊断有较大的价值。3.有一定程度的辅助诊断价值或参考价值。
ECG for the diagnosis of certain heart disease has a special significance. For example, myocardial infarction, it has a unique change of the ring, according to which myocardial infarction can be located. Another example is arrhythmia, ECG can accurately understand the disorder of ectopic pacemaking and so on. However, the electrocardiogram did not record anatomical changes. Some patients have clinically diagnosed rheumatic heart disease, mitral stenosis, murmur is obvious, but the ECG may also be normal. Therefore, normal ECG can not be sure that the patient has no heart disease. On the contrary, due to some causes ECG changes, abnormal patterns appear, it is not a heart attack. Some diseases have been cured, but ECG may be left abnormal. Although some ECG changes, but the clinical significance of the reference is not specific. Therefore, we must not think that with the ECG can replace clinical or other tests. About the practical value of ECG, according to a large number of clinical practice, can be broadly divided into three categories. 1. Have a diagnostic value. 2. The diagnosis of greater value. 3. A certain degree of auxiliary diagnostic value or reference value.
