分析一份心电图首先要初步判断有无心律失常存在,其次再确定属于那一类型,是简单心律失常还是复杂心律失常,结合临床有助于鉴别。众所周知,窦房结的激动情况在心电图上不能直接反映出来,正常时窦房结发出的激动都能传到心房产生 P 波,继而传到心室产生 QRS 综合波,即为窦性心律。通常借助P 波的形态与频率来间接了解窦房结的节律性。当心电图见到下列各种改变时,应考虑有心律失常存在。
Analysis of an ECG must first determine whether there is a preliminary determination of arrhythmia, and then determine which type is, simple arrhythmia or complex arrhythmia, combined with clinical help identify. As we all know, the excited state of the sinus node can not be directly reflected in the ECG, the normal sinus node excited sent to the atrium can produce P wave, and then spread to the ventricular QRS complex, which is sinus rhythm. Usually with the help of P wave morphology and frequency to indirectly understand the rhythm of the sinus node. When the electrocardiogram to see the following changes, should consider the existence of arrhythmia.
