Skin impedance measurements used for early onset of hypoglycaemia in diabetic patients

No.98CH36286), None

Hypoglycaemia is a common danger in patients with diabetes, particularly in Type I insulin dependent diabetes mellitus (IDDM). During hypoglycaemia, physiological parameter changes occur in patients, due to the sympathetic nervous system, of which the most predominant parameter is sweating. This paper describes the development of a skin impedance meter used to analyse sweating from Type I IDDM patients and ...

Curve registration for study of P-wave morphing during exercise

The P-wave shape analysis remains an interesting objective in various situations. In this paper, the aim is to investigate how the P-wave morphology changes during time-varying effort. To perform this task, a method, Self- Modeling Registration (SMR), derived from the Curve Registration (CR) theory is used. This method permits to link different shapes by mean of time warping functions. First, ...

E. van der Wall'}] Proceedings of Computers in Cardiology Conference, None

Magnetic resonance imaging (MRI) of the heart precludes dynamic exercise. Therefore, stress MRI is accomplished by pharmacological stimulation, e.g., by the synthetic adrenergic agent dobutamine. With dobutamine stress, an autonomic defense (a shift of the sympathovagal balance towards vagal predominance) is to be expected. To assess this, the authors measured heart rate (HR) and the percentage 0.07-0.14 Hz low-frequency heart ...

Experimental &#x2018;jet lag&#x2019; causes sympathoexcitation via oxidative stress through AT<inf>1</inf> receptor in the brainstem

Circadian disruptions through frequent transmeridian travel, rotating shift work, and poor sleep hygiene are associated with an array of physical and mental health maladies, including the abnormal autonomic nervous system. We have demonstrated that the oxidative stress through AT1 receptor in the brain activates sympathetic nervous system. The aim of the present study was to determine whether experimental `jet lag' ...

Children with severe motor and intellectual disabilities (SMID) find it almost impossible to communicate whether they are feeling comfortable or uncomfortable. Most of the children with SMID rely on medical care involving disposable-type life support devices such as tracheostomy tubes or gastric tubes. It is believed that the insertion and removal of these medical devices could cause extreme physical pain ...

  • Excitable Tissue

    The nervous system includes voluntary and autonomic (sympathetic and parasympathetic) systems. This book is devoted almost entirely to the voluntary system. The system consists mostly of excitable tissue¿¿-¿¿sensory receptors, neuron cell bodies, axons, and muscle fibers. If you step on a sharp object, it stimulates sensory receptors that in turn stimulate neurons; the latter send action potentials (APs) via axons to interneurons and motoneurons in the spinal cord. The motoneurons send APs to the appropriate muscles, which contract so as to make you jump off the object. Some of the activity involves atomic dimensions and, because distances are so small, time intervals are correspondingly small. It takes a factor of about 107 to transform atomic distances into dimensions that are familiar to us. For example, most atoms and simple compounds, if magnified by 107, turn out to be 3 mm (0.12 in.) in diameter. One centimeter multiplied by 107 equals 100 km (62 mi.). In time, one second multiplied by 107 is almost equal to 4 months. Sensory receptors are usually at rest when they are unstimulated. Neuron cell bodies are at rest when they are not generating APs, while muscle fibers and axons are at rest when they are not carrying APs (that is, no APs are propagating along the muscle fiber or axon). Body tissues are bathed in fluid that has an excess of sodium and chloride ions. Internally, excitable tissue at rest has an excess of potassium and large organic negative ions. This external-internal combination forms a battery that makes the inside of the tissue 60 to 90 mV more negative than the outside. The electric field across the membrane is very high¿¿-¿¿up to 12,000 V/mm. The physiologically compatible ionic concentrations are maintained by sodium and potassium pumps.
