13. Left ventricular fibre architecture in man.
In order to investigate the possibility of regional variation of ventricular structure, 25 normal postmortem human hearts were studied by inspection of cavity shape and subepicardial fibre orientation, by dissection, and by the histology of sections in two orthogonal planes. Ventricular architecture was complex. Inlet and outlet long axes were separated by 3

14. Ultrasound assessment of normal hemidiaphragmatic movement: relation to inspiratory volume.
BACKGROUND--Traditionally the radiological assessment of diaphragmatic movement has relied on fluoroscopy. Ultrasound scanning has recently been shown to be a sensitive and reproducible method of assessing hemidiaphragmatic movement in normal subjects. A study was undertaken to examine how movement of the diaphragm measured by ultrasound scanning relates to

15. Movement of the Feline Esophagus Associated with Respiration and Peristalsis. AN EVALUATION USING TANTALUM MARKERS
The outer, lateral esophageal walls in the distal half of the esophagus in each of five cats were labeled with small tantalum wires. About 8 wk later, esophageal motion associated with respiration and peristalsis, induced by injecting barium boli (5 ml each) into the proximal esophagus, was recorded on cine and serial biplane roentgenograms while recording i

16. Myocardial perforation by flexible Elema endocardial pacing catheters 1
Hurwitz, B. J., Zion, M. M., and Promund Obel, I. W. (1974).Thorax, 29, 678-684. Myocardial perforation by flexible Elema endocardial pacing catheters. Myocardial perforation as a complication of permanent endocardial pacing with flexible Elema catheters is described in nine patients. In eight patients pacing failed, but there were no other serious ill-effec

17. Changes in ventilation and its components in normal subjects during sleep.
Non-invasive measurements were made of ventilation, its derivatives, the contributions of abdomen and rib cage and arterial oxygen saturation in six healthy normal men whilst awake and during sleep. Minute ventilation fell significantly during slow wave (SW) sleep and rapid eye movement (REM) sleep (awake = 6.3 1 min-1, SW sleep = 5.7 1 min-1, REM sleep = 5.

18. Hypoxia and hydrothoraces in a case of liver cirrhosis: correlation of physiological, radiographic, scintigraphic, and pathological findings
Stanley, N. N., Williams, A. J., Dewar, C. A., Blendis, L. M., and Reid, Lynne (1977).Thorax, 32, 457-471. Hypoxia and hydrothoraces in a case of liver cirrhosis: correlation of physiological, radiographic, scintigraphic, and pathological findings. A case is reported of liver cirrhosis complicated by cyanosis and recurrent right hydrothorax. A diagnostic pne

19. Unilateral magnetic stimulation of the phrenic nerve.
BACKGROUND--Electrical stimulation of the phrenic nerve is a useful non-volitional method of assessing diaphragm contractility. During the assessment of hemidiaphragm contractility with electrical stimulation, low twitch transdiaphragmatic pressures may result from difficulty in locating and stimulating the phrenic nerve. Cervical magnetic stimulation overco
