Schrumpf (1920) was the first to describe a clinical electrocardiogram assumed to represent atrial dissociation. He figured a curve apparently normal with a series of rhythmic and independent deflections resembling auricular waves superadded to it. In his case these independent deflections were ineffective to evoke ventricular responses, their rate was not rapid, and they fell in varying time-relation with the waves of the fundamental rhythm which they failed to affect.Since then a number of electrocardiograms showing essentially the same events have been published by Bay

After removal of artefacts, the mean monitoring time was 22 h08 (8 h54). All patients had impaired cerebral autoregulation during their monitoring time. The mean IAR index was 17 (9.5) %. During H 0 H 6 and H 18 H 24 , the majority of our patients; respectively 53 and 71 % had an IAR index > 10 %. Conclusion According to our data, patients with septic shock had impaired cerebral autoregulation within the first 24 hours of their admission in the ICU. In our patients, we described a variability of distribution of impaired autoregulation according to time.

Provocation tests have a high sensitivity and specificity for the diagnosis of vasospastic angina. Although it is rare, these tests have the potential risk of irreversible spasm leading to arrhythmia and death.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
