Einthoven's nomenclature remains today with theR waveof the ECG occurring when the heart contracts. Since then five other needle deflections have been detected during a single heart beat, giving rise to the P, QRS, T andU waves(Fig. 24.1). TheP waveoccurs when the two upper chambers of th...
4. Important in the differential diagnosis of QT prolongation and configuration of the T wave is information about the circumstances in which the ECG changes occur. In our patient this is helpful to exclude many of the causes ...
在1991年由Walder和Spodick提出global T wave inversion这一心电图新概念。其心电图特点:全 导联T波倒置;对称型T波倒置占优势,少数为非对 称性T波倒置;QT和QTc间期延长,对称型T波倒 置QTc间期延长较非对称性更显著;Q—T离散度在 正常范围;可与束...
Conclusion For children with T wave changes of ECG, the anal-ysis of T wave changes and premature beat situation, as well as detection of myocardial enzyme spectrum should be strengthened in order to find out the etiology and perform early treatment.%目的 分析小儿心电图T波改变的病因,特点,为...
The incidence of the ECG changes was 71.5% in the group with subarachnoid haemorrhage. The figures for the groups with intracerebral haemorrhage and unclassified cerebrovascular accidents were 57.1 and 41.1%, respectively. Attention has been... KE Kreus,SJ Kemilä,JK Takala - 《Indian Journal of...
Because the ST segment and the T-wave are electrophysiologically related, changes in the ST segment are frequently accompanied by T-wave changes. The term ST-T segment changes (or simply ST-T changes) is used to refer to such ECG changes. ...
The heartbeat is recorded on an electro- cardiogram (ECG) as a characteristic trace determined by changes in the electrical activity of the heart muscle. The T wave is a component of this waveform that is associated with the repolarization phase of the action potentials. It is asymmetrical in...
