The Electrocardiogram after Mastectomy

T HE CHARACTERISTICS of the electrocardiographic tracing are determined by three independent variables. The first of these involves the potentials generated by the myocardium during depolarization and repolarization. These potentials can be altered by a wide variety of physiologic states, as well as by intrinsic disease of the myocardium. The second factor relates to the properties of the extra...

Dyspnoea after pneumonectomy.

We report the case of a 61 yr old male, who developed a severe right-to-left shunt through a patent foramen ovale, in the absence of elevated right-sided heart pressures, two months after a left-sided pneumonectomy. This is considered to be a rare complication after pneumonectomy. However, taking into account the approximately 20% incidence of patent foramen ovale in the general population, we ...

Respiratory function after pneumonectomy.

Regional lung function after pneumonectomy.

Hail, D. R. (1974). Thorax, 29, 425-431. Regional lung function after pneumonectomy. Regional lung function was studied with xenon-133 in 10 patients with bronchial carcinoma before and again three to six months after pneumonectomy. It was found that ventilation and perfusion were often considerably reduced in the tumour-bearing lung and that the greater part of the cardiac output had apparentl...
