Central hemodynamic responses to Electrical Stimulation (ES)-induced contractions were compared with voluntary contractions of the lower limb muscles in twenty subjects (legs). All subjects were healthy volunteers with normal venous capacitance and no reflux. Exercise protocols consisted of static and continuous loaded and unloaded lower leg muscle contractions produced by: 1) voluntary contrac...

Introduction: It is well known that the tendency toward thrombosis is increased in cancer patients. The increase in cancer procoagulant and tissue factor levels, endothelial damage, and stasis due to compression are among the most accused causes of thrombosis in cancer patients. Hypereosinophilia is a rare condition that causes endothelial damage leading to thrombosis. <s...

FISHER, MICHAEL L., AND DONALD 0. NUTTER. Cardiovascular reJlex adjustments to static muscular contractions in the canine hindlimb. Am. J. Physiol. 226(3) : 648-655. 1974.-The cardiovascular response to 30-s tetanic muscular contractions was studied in the anesthetized dog. A significant systemic pressor reflex occurred during handlimb contractions evoked by both spinal ventral nerve root (Ls L...

turkmen horse is one of the oldest and purest breeds in the world, but there is no information on doppler echocardiographic parameters in this horse. in the present study, pulsed-wave (pw) doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing turkmen horses. no cardiac disease was detected with two-dimensional (2-d) real-time, m-mode, and colour flow mapping. d...

introduction the sensation of palpitations may either be the initial or the only symptom of cardiac arrhythmia. we describe a case of a visible clear temporal relationship between standard doses of oxazepam and palpitation. case presentation a 48-year-old man presented to the cardiac care unit with systolic heart failure. he was commenced on a medication regimen of routine drugs of patient’s he...

In various kinds of cultured cells, it has been reported that the membrane potential exhibits fluctuations with long-term correlations, although the underlying mechanism remains to be elucidated. A cardiac muscle cell culture serves as an excellent experimental system to investigate this phenomenon because timings of excitations can be determined over an extended time period in a noninvasive ma...

OBJECTIVE The aim of this study was to evaluate whether frequent premature ventricular contractions originating from the right ventricular outflow tract remodel the cardiac structure and function in patients with a "seemingly normal heart" and whether radiofrequency ablation can reverse this remodeling. METHODS Sixty-eight patients with idiopathic frequent premature ventricular contractions o...
