... and Ranolazine ameliorated the phenotype. Understanding the insecticides’ impacts upon electromechanical properties of the heart is important for the development of therapeutic approaches to treat cases of pesticides intoxication. β-Cyfluthrin arrhythmias INa-L insecticide pyrethroid ranolazine...

...-C1 neurons were selectively ablated using cell-specific immunotoxin (dopamine-β hydroxylase saporin [DβH-SAP]) and measures of cardiac autonomic tone, function, and arrhythmia incidence were evaluated. Cardiac autonomic imbalance, arrhythmogenesis and cardiac dysfunction were present in HF rats...

... to troponin C, secondary to cross-bridge formation. Thus, during positive inotropy, EMD 57033 is unlikely to provoke arrhythmias due to effects on SR Ca 2+ handling. In intact cells, its effects on Ca 2+ handling would be expected to protect against arrhythmias. Correspondence : Dr J. A. Lee (e...

... of training may be of relevance to individuals with elevated sympathetic activity who may be at risk of myocardial ischaemia, serious ventricular arrhythmias or sudden cardiac death. Clinical Science (1992) 82,357-362 (Printed in Great Britain) Exercise training reduces the sympathetic component of the blood...

... by an effect on MAP duration rather than on local conduction time. After /3-adrenoceptor blockade the effect of a bolus injection of potassium chloride on MAP duration was greater and conduction time was increased. Key words: arrhythmias, electrocardiogram, hyper- kalaemia, intraventricular conduction...

... when breaths were shorter: always at about 2 s after the start of inspiration. 4. An autonomic reflex mechanism, equivalent to that causing sinus arrhythmia, appears to be the most likely explanation. 12 12 1983 7 2 1984 © 1984 The Biochemical Society and the Medical Research Society...

... ischaemic perfusion such hearts showed a more marked rise in resting tension and decline in heart rate than hearts from normally fed animals. Such hearts also had an increased incidence of arrhythmias and a slight reduction in developed tension. The initial responses of these hearts from fat-fed rats...
