Electrocardiographic changes during injection sclerotherapy.

Electrocardiographic changes during oesophagogastroscopy.

BACKGROUND Oesophagogastroduodenoscopy (EGD) should be very safe, but there are many potential hazards, although the rate of serious complications is small. There are so many complications that can arise during this procedure. Most of these complications involve the respiratory or cardiovascular systems, especially in sick or sedated patients.The aim of this study was to determine the various e...

Electrocardiographic Changes during Lithium Treatment

Electrocardiographic changes have been reported during therapy with psychotropic drugs—such as tricyclic anti-depressants (Schou 1963 ; Burrows et al., 1976 ; Reed and McKim 1978) and lithium (Tilkian et al., 1976a, 1976b; Wren and Dana 1976; Jefferson and Greist 1979). Lithium Carbonate affects ionic fluxes across cell membranes—-particularly those of sodium, potassium, calcium and magnesium (...

Electrocardiographic changes during pressure breathing.

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...

Injection sclerotherapy in portal hypertension.

Mucus synthesis by the human gall bladder EDITOR,-I was interested to read the papers by Rhodes and colleagues concerning mucus synthesis by the human gall bladder, its apparent inhibition by aspirin, and other non-steroidal anti-inflammatory drugs (NSAIDs), and the suggestion that aspirin might prevent cholesterol gall stone formation by this action As gall bladder mucus glycoprotein (mucin) i...
