    Increased myocardial contractility in short-term Type 1 diabetic patients: an echocardiographic study (1985)

    Notes: Summary Cardiac function was investigated by echocardiography in 24 short-term Type 1 diabetic patients with a mean diabetes duration of 7 years (range 4–14 years) during conditions of ordinary metabolic control. Compared to 24 age and sex matched normal control subjects, measurements of myocardial contractility as left ventricular fractional shortening and mean circumferential shortening velocity were increased by 12% and 20% respectively. Another 8 Type 1 diabetic patients were examined during conditions of poor (hyperglycaemia and ketosis) and good metabolic control. Following improved glycaemic control, left ventricular fractional shortening and mean circumferential shortening velocity decreased by 16% and 24% respectively. Our findings show that short-term Type 1 diabetes is associated with increased myocardial contractility. Furthermore, this condition is related to the state of metabolic control.

    Evaluation of a constant-temperature hot-wire anemometer for respiratory-gas-flow measurements (1979)

    Notes: Abstract The performance of a constant-temperature hot-wire anemometer for respiratory-gas-flow measurement has bee investigated. It is shown that the anemometer satisfies common demands with respect to accuracy, response time and to insensitivity to humidity and temperature variations. A calibration method is suggested that permits correction for variation of the flowmeter signal caused by changes of the gas composition. Finally, a procedure for linearisation of the flowmeter signal as a function of flow rate is presented.
