heart arrest/scopolamine

Several specific and sensitive new methods for determining atropine and its metabolites in biological fluids have increased the possibility to characterise the pharmacokinetic properties of this antimuscarinic agent. Following i.v. injection, atropine disappears very quickly from the circulation,

A 43-year-old male with history of recurrent episodes of syncope, non-sustained wide complex tachycardia and structurally normal heart was studied. Syncope was induced with upright tilt provocation, while monitoring cerebral blood flow velocity with Doppler ultrasound, concurrently with invasive

The purpose of this study was to define the history and prognosis of 12 patients (8 males, 4 females) with syncope of unknown origin (5 to 15 episodes), who developed prolonged asystole or complete AV block during the upright tilt test (UTT). The mean age (+/- SD) of the patients was 29 +/- 7.4

The objective of this study was to investigate the protective effects of scopolamine and penehyclidine hydrochloride on acute cerebral ischemia-reperfusion injury after cardiopulmonary resuscitation, and the effect on cytokine levels. Eighty patients with cardiac arrest admitted to our hospital from

The types of cardiac rhythm in patients with sudden death may vary considerably, depending on the underlying cardiac disease. Although ventricular tachyarrhythmias are likely to be the most common causes, a significant proportion of patients may die suddenly due to asystole, electromechanical

Vasovagally mediated cardiac asystole has been proposed as a potential cause of sudden cardiac death. To assess this possibility and identify characteristics that define patients with vasovagally mediated asystole, head-upright tilt-table testing was performed in 50 consecutive patients (26 women
