Vulpian in France and Hoff and Ludwing in Germany first studied atrial fibrillation in experimental animals. In clinical medicine, de Senac and others, first observed irregular and fast pulse. Hering in 1903 described "pulsus irregularis perpetuus" as a distinct arrhythmia. ⋯ Mackenzie was another British author who played an important role in the clarification of atrial fibrillation, particularly after Cushny convinced him, that the so-called nodal rhythm was atrial fibrillation. Einthoven reported the first ECG of atrial fibrillation without recognizing its true nature. Finally in 1909 and 1910 Lewis in London and, Rothberger and Winterberg in Vienna established atrial fibrillation as a clinical entity.

[Importance of the ECG for evaluation of severity of pulmonary embolisms].
To evaluate whether it is possible on the basis of ECG examination to judge the haemodynamic impact of pulmonary embolism. ⋯ The absence of ECG changes does not rule out serious pulmonary embolism. The finding of typical ECG changes is very frequently associated with pulmonary hypertension, right ventricular dilatation and a serious haemodynamic finding.
