Electrocardiographic Changes During Selective Coronary Cineangiography

S ELECTIVE coronary angiography is being used with increasing frequency for clinical diagnosis in several forms of heart disease. Except for the works of Ross,' Hale and Jefferson,2 and Lehman and associates,3 there have been no detailed reports in the literature about the electrocardiographic changes accompanying the injection of radiopaque media selectively into the coronary arteries of man. ...

Magnetic resonance--guided coronary artery stent placement in a swine model.

BACKGROUND Magnetic resonance (MR)--guided coronary artery stent placement is a challenging vascular intervention because of the small size of the coronary arteries combined with incessant motion during the respiratory and cardiac cycles. These obstacles necessitate higher temporal and higher spatial resolution real-time MR imaging techniques when compared with interventional peripheral MR angi...

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 (...
