The trigeminocardiac reflex (TCR) is defined as the sudden onset of parasympathetic dysrhythmia, sympathetic hypotension, apnoea or gastric hyper-motility during mechanical/thermal stimulation of any of the sensory branches of the trigeminal nerve. The risk factors that are already known for increasing the prevalence of the TCR include anatomical location, hypercapnia, hypoxemia, light general anaesthesia, age (more pronounced in children), the nature of the provoking stimulus (stimulus strength and duration) and different drugs. Already different potential confounders are also identified. This discussion about risk factors has its importance because of the substantial consequences for functional outcome after intraoperative TCR occurrence. But there remains still a substantial lack of thorough understanding of the TCR, the current treatment options for patients with TCR include a mostly empirical approach: (i) risk factor identification and modification; (ii) prophylactic measures of vital signs and (iii) administration of vagolytic agents or sympathomimetics. In this context, we have now created different thinking models so that we can preoperatively plan a skull base surgery procedure safely in relation to a potential occurrence of the TCR episodes. This chapter provides an overview of this unique reflex that presents a unique interaction between heart and brain. In addition, this also illustrates the mechanism of various cardiac rhythm changes related to the TCR.

We know a lot of things about cardiac rhythms and their abnormalities, but there are some things that are still waiting to be discovered and, therefore, require more study. In this book, the authors put a little light on those matters, which are not well known yet. The authors have exposed some of such cardiac arrhythmias, especially those affecting the atria of the heart (with special emphasis on fibrillation and flutter atria). By means of this book, readers can broaden their knowledge about this specific topic of supraventricular arrhythmias. They can also find a special chapter on Amiodarone as a cardiac antiarrhythmic drug, which is very revealing, even today.

Trigeminocardiac Reflex is a comprehensive tutorial reference to the science, diagnosis, and possible treatment of the trigeminocardiac reflex (TCR) that is usually initiated when the trigeminal nerve is disturbed during intercranial surgery. Since first reported in 1999 by co-Editor Bernhard Schaller, the research focused on TCR is expanding. While its instance is rare, new discoveries are not only increasing diagnosis, but also providing more effective treatment protocols. This text is ideal as a reference for clinical and research neurologists, as a general introduction for clinical presentation, and as a foundation for new research. - Represents the first tutorial reference focused on the Trigeminocardiac Reflex (TCR) - Content organized by two of the leading scientists in the area, Dr. Tumul Chowdhury (University of Manitoba) and Prof. Bernhard Schaller (University of Southampton) - Defines TCR, its onset, and possible treatments - Establishes a knowledge base for the future study of the TCR and treatment protocols

The trigemino-cardiac reflex (TCR) is a well established brain-stem reflex and commonly manifests as bradycardia, asystole, hypotension and / or apnea. This phenomenon was extensively explored in the recent past. However, the area related to its exact bio-physiological mechanism, neuro-anatomical linkages, clinical implications, its role in non neurological events and future directions should need to be further investigated. Therefore, this present research topic on TCR would mainly focus on various aspects of TCR and present a comprehensive and exhaustive overview about a phenomena that gains more and more interest during the last few years. Our goal is to present models about the different aspects of the TCR to develop in-depth understanding of TCR.

This book on the local and systemic manifestations and correlates of temporomandibular joint disorders (TMDs) encompasses the two intertwined facets of translational science – translational research and translational effectiveness – as they relate specifically to TMDs. The first part of the book, on recent translational research, focuses on topics such as the neuroanatomy and neurophysiology of the trigeminal nerve and trigeminal network system, the manifestations of neuroinflammation in TMDs, and the molecular mechanisms underlying TMDs. The second part discusses the clinical effectiveness of treatment approaches from the perspective of evidence-based dentistry, with careful attention to the critical relationships between dental malocclusions, the signs and symptoms of TMDs, and airway/breathing disorders. Interventions to correct for malocclusal conditions that lead to TMDs are examined, with explanation of the ways in which they can ameliorate a variety of local and systemic symptoms. This will be an excellent reference book for established practitioners, residents, interns, and students as well as a powerful cutting-edge document for researchers in the field.
