It was recognized many years ago that the form of the electrocardiogram could be modified by a voluntary increase of breathing pressure, as during the Valsalva manceuvre (Kahn, 1909). During the early part of the second world war further studies were undertaken by German workers (Zettel and Fink, 1939; Muller, 1941), and it was found that it was altered even by the small fluctuations of breathi...

THE electrocardiographic pattern of 164 patieuts with head injury was studied and compared with two control groups: 100 patients with limb trauma aud 164 healthy subjects. In the group with the head injury the electrocardiographie findings were correlated with the level of consciousness. The possible relationship between head trauma and eleetrocardiographic changes was first suggested by Bramwe...

background: there is evidence that electrocardiographic (ecg) changes occur during elective cesarean section in parturients. these changes, mostly in the form of st-segment depression, have been noted in either regional anesthesia or general anesthesia. we performed this study to compare hemodynamic variables and electrocardiographic changes suggestive of myocardial ischemia following administr...

LEOPARD syndrome is an autosomal dominant hereditary disease, which is characterized with cutaneous pigmented patches, electrocardiographic changes, ocular hypertelorism, retarded growth, pulmonic stenosis, genital abnormalities and congenital deafness. The gene of this disease have high penetrance but expression is varied and incomplete forms may be seen. We report a 23 year-old woman wi...

By causing numerous changes in the cardiovascular system, ageing leads to a decreased threshold for clinical manifestation of heart disease. The aim of this study was to define the existence of cardiac structural and functional changes in healthy dogs of different age. Radiographic, electrocardiographic (ECG) and echocardiographic examinations of 20 clinically healthy German Shepherd dogs were ...

background: preeclampsia is a condition observed during pregnancy and threatens the life of both mother and fetus. there are studies which suggest that preeclampsia play a major role in the left ventricular mass. the aim of this study is to compare the electrocardiographic changes in normal pregnant and preeclamptic women. methods: the studied groups consisted of 48 mild preeclamptic, 33 severe...
