Abstract:
Background: Bradycardia occurring during laparoscopic surgery potentially leads to cardiac arrest and adverse outcomes. Apart from the vagal reflex for its genesis, the knowledge on frequency and risk factors is limited. 
 Objectives: To identify the bradycardia frequency and time points for its occurrence during laparoscopic surgeries.
 Methodology: In this hospital-based cross-sectional study, anaesthesia-related incident reports on bradycardia were collected from January to December 2019. Bradycardias (heart rate less than 60/minute) that occurred during laparoscopic surgeries wer

Abstract:
Hallmarks of the mammalian diving response are protective apnea and bradycardia. These cardiorespiratory adaptations can be mimicked by stimulation of the trigeminal ethmoidal nerve (EN5) and reflect oxygen-conserving mechanisms during breath-hold dives. Increasing drive from peripheral chemoreceptors during sustained dives was reported to enhance the diving bradycardia. The underlying neuronal mechanisms, however, are unknown. In the present study, expression and plasticity of EN5-bradycardias after paired stimulation of the EN5 and peripheral chemoreceptors was investigated in the in situ wo

Abstract:
Neonatal rodents deficient in medullary serotonin neurons have respiratory instability and enhanced spontaneous bradycardias. This study asks if, in Pet-1−/− mice over development: 1) the respiratory instability leads to hypoxia; 2) greater bradycardia is related to the degree of hypoxia or concomitant hypopnea; and 3) hyperthermia exacerbates bradycardias. Pet-1+/+, Pet-1+/−, and Pet-1−/− mice [postnatal days (P) 4–5, P11–12, P14–15] were held at normal body temperature (Tb) and were then made 2°C hypo- and hyperthermic.

Comorbid diabetes and depression constitutes a major health problem, worsening associated cardiovascular diseases. Fluoxetine’s (antidepressant) role on cardiac diabetic complications remains unknown. We determined whether fluoxetine modifies cardiac vagal input and its serotonergic modulation in male Wistar diabetic rats. Diabetes was induced by alloxan and maintained for 28 days. Fluoxetine was administered the last 14 days (10 mg/kg/day; p.o). Bradycardia was obtained by vagal stimulation (3, 6 and 9 Hz) or i.v. acetylcholine administrations (1, 5 and 10 μg/kg).

Abstract:
Cardiovascular self-organized criticality (SOC) has recently been demonstrated by studying vasovagal sequences. These sequences combine bradycardia and a decrease in blood pressure. Observing enough of these sparse events is a barrier that prevents a better understanding of cardiovascular SOC. Our primary aim was to verify whether SOC could be studied by solely observing bradycardias and by showing their distribution according to Zipf’s law. We studied patients with vasovagal syncope. Twenty-four of them had a positive outcome to the head-up tilt table test, while matched patients had a negati

Abstract:
Microinjection of increasing doses of L-glutamate (L-Glu, 0.03-5.0 nmol/100 nl) into the nucleus tractus solitarii (NTS) produced a dose-related pressor and bradycardic response. Prazosin virtually abolished the pressor response but produced no changes in the bradycardic response to L-Glu, indicating that bradycardia is not reflex in origin. The bradycardic response was blocked by atropine. In three different groups of rats, excitatory amino acid receptors in the NTS were blocked by increasing doses of kynurenic acid (0.5, 2.0, and 10.0 nmol/100 nl) and the pressor and bradycardic responses to

Bradycardia, frequently observed in preterm infants, presents significant risks due to the immaturity of their autonomic nervous system (ANS) and respiratory systems.

Chronic dosing of Ringer and ZD7288 changed neither eye diameter nor development rate. Chronic dosing of ZD7288 did not significantly alter CAM vessel density close to the embryo (2, 3 and 4 mm) but

Bradyarrhythmias can be benign, requiring no treatment; however, acute unstable bradycardia can lead to cardiac arrest.

Abstract:
BRASH syndrome is an acronym that stands for bradycardia, renal failure, AV node blocker, shock and hyperkalemia. The syndrome is precipitated by synergism from AV nodal blocking agents and hyperkalemia. The combination of the AV nodal blockade and renal failure leads to a cycle of severe bradycardia and hyperkalemia. We will discuss a case of BRASH syndrome with a 68 year old female who presented with generalized weakness and was found to be hypotensive, bradycardia, in acute renal failure with hyperkalemia likely related to metoprolol and amlodipine use.

Here we present the case of a male in his 70’s who presented with diarrhea and a syncopal episode and was ultimately diagnosed with BRASH syndrome. The acronym BRASH is a novel way to describe the constellation of symptoms that result in unfortunate synergistic affects that can result in profound bradycardia. In the setting of hyperkalemia and concurrent use of atrioventricular nodal blockers, there is potential for a worsening bradycardia and inevitable cardiovascular collapse if not identified.

Abstract:
Currently, several studies and experiments are being done to create a new generation of ultra-low-power wearable sensors. For instance, our group is currently working towards the development of a high-performance flexible pressure sensor. However, with the creation of new sensors, a need for a standard test method is necessary. Therefore, we opted to create a standardized testbed to evaluate the pressure applied to sensors. A pulse wave is generated when the heart pumps blood causing a change in the volume of the blood vessel. In order to eliminate the need of human subjects when testing press

Abstract:
Background/Purpose: Post-operative delirium leads to significant morbidity in elderly patients, yet there is no regimen to prevent POD. Opioid use in the elderly surgical population is of the most significant risk factors for developing POD. The purpose of this scoping review is to recognize that Dexmedetomidine mitigates cognitive dysfunction secondary to acute pain and the use of narcotic analgesia by decreasing the amount of norepinephrine (an excitatory neurotransmitter) released during times of stress. This mechanism of action also provides analgesia through decreased perception and modul
