Palmar sweating as an indirect but non-invasive measure of sympathetic activity was estimated by means of a unique hygrometer under right ventricular (RV) rapid pacing (up to 150 beats min-1) replicating VT, and concurrent monitoring of aortic blood pressure in five patients with various kinds of cardiac arrhythmias in our electrophysiological laboratory. The peak palmar sweating rate in arbitrary units was augmented as the RV pacing rate increased and was proportional to the pacing-induced fall in systolic blood pressure (SBP), with a correlation coefficient of more than 0.903 (P<0.006). The slope of linearity between the sweating rate and the fall in SBP varied among individual patients, with greater sweating amplitude in the younger patients even with the same extent of fall in SBP. This preliminary study suggests sympathetic acceleration caused by haemodynamic deterioration under simulated VT, and therefore this protocol may be able to predict the haemodynamic tolerability of sustained monomorphic VT.","PeriodicalId":77071,"journal":{"name":"Clinical physiology (Oxford, England)","volume":"20 2","pages":"85-8"},"PeriodicalIF":0.0,"publicationDate":"2000-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1046/j.1365-2281.2000.00219.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21587346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationship between decreased complexity of heart rate dynamics and sudden cardiac death has been documented. An understanding of circadian variation in the complexity of cardiac dynamics may be important to predict and prevent sudden cardiac death. Dynamic 24-h electrocardiographic recordings were obtained from 30 healthy ambulant subjects aged 41-50 years, and the digitized data were partitioned into sections of 30 min duration. For each section, four indexes obtained from separate algorithms of non-linear dynamics of the RR interval--modified correlation dimension, Lyapunov exponent, approximate entropy, and fractal dimension--were calculated. Normalized low-(0.04-0.15 hertz) and high-frequency (> 0.15 hertz) components were also calculated. All four indexes of non-linear dynamics showed a remarkably similar circadian rhythm: a prominent morning dip preceded by a steep decline during the late night, a recovery during the evening and a peak around midnight. In the morning, the low-frequency component rose rapidly with concomitant reduction in the high-frequency component. The complexity of cardiac dynamics decreases significantly in the morning, and this may contribute to the ominously increased rate of cardiac death in the morning hours.","PeriodicalId":77071,"journal":{"name":"Clinical physiology (Oxford, England)","volume":"19 1 1","pages":"56-67"},"PeriodicalIF":0.0,"publicationDate":"1998-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4070/KCJ.1998.28.3.382","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70442544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whole body energy expenditure was measured by the open circuit ventilated hood system. Forearm blood flow was measured by venous occlusion strain-gauge plethysmography. The uptake of oxygen in the forearm was calculated as the product of the forearm blood flow and the difference in arteriovenous oxygen concentration. The glucose-induced thermogenesis in the 120 min following the glucose load was significantly reduced by beta-adrenergic inhibition with approximately 50% from 63.9 +/- 5.8 kJ 120 min-1 (mean +/- SE) to 27.8 +/- 9.8 kJ 120 min-1 (P < 0.01). Almost the entire reduction took place from 60 to 120 min (P < 0.005). The integrated glucose-induced forearm oxygen uptake in the period 60-120 min following the glucose load was significantly reduced after beta-adrenergic inhibition from 103 +/- 28 mumol 100 g-1 60 min-1 to 29 +/- 29 mumol 100 g-1 60 min-1 (P < 0.05). The noreadrenaline concentration in the arterial blood was not increased in the baseline period compared to healthy elderly; it increased following the glucose load while there was no demonstrable increase in adrenaline concentration in the two experiments. It is suggested that these patients have increased sensitivity of the beta-adrenergic receptors and an early facultative component of the glucose-induced thermogenesis in part takes place in the forearm.","PeriodicalId":77071,"journal":{"name":"Clinical physiology (Oxford, England)","volume":"14 5","pages":"489-99"},"PeriodicalIF":0.0,"publicationDate":"1994-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1475-097x.1994.tb00408.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18819659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were no significant differences with regard to basal levels of circulating CGRP between women with PRP and the control group; median 15.5 (range 10-48) vs. 14 (range 10-69) pmol l-1, respectively. However, treatment with MgSO4 infusion significantly decreased circulating CGRP in women with PRP only from median 15.5 (range 10-48) to 10 (range 10-110) pmol l-1) (P < 0.05). On the other hand 14 days of treatment with nifedipine did not affect circulating CGRP in either of the investigated groups. Erythrocyte magnesium (ery-Mg) levels increased significantly after MgSO4 infusion in women with PRP (2.43 +/- 0.13 vs. 2.52 +/- 0.15 mmol l-1, P < 0.05) but not in the controls (2.51 +/- 0.24 vs. 2.57 +/- 0.28 mmol l-1, ns).

Thigh muscle + bone cross-sectional area (CSAM+B) and lower limb muscle plus bone volume (LLVM+B) of the GHD patients were 66.1 +/- 13.7% and 47.6 +/- 6.8% of those recorded in the controls (P < 0.01), whereas no difference in CSA/height2 was found between the two groups.

Quadriceps MVC increased by 9.8 +/- 12.0% (P < 0.02), differences from the controls being still significant, whereas the F/CSA and F/BM did not change. A right shift of the integrated EMG/Force relation, with no change in the maximal integrated EMG (iEMG) activity, was observed in the patients after treatment.
