Falls are one of the most common reasons for patients to present to the emergency department. Syncope is a common cause of falls, which disproportionately affects older people. In most cases, syncope can be confirmed with a detailed history and simple bedside tests, but tilt table testing remains an invaluable diagnostic adjunct in more complex cases. Often misunderstood, the tilt table test is a useful way to reproduce a patient's symptoms in a safe and controlled environment. The tilt table test is considered positive if the patient experiences symptoms associated with a drop in blood pressure or postural tachycardia. The test can support a diagnosis and can direct therapeutic interventions.

The aim of this study was to evaluate the feasibility of using a biofeedback-enhanced robotics-assisted tilt table (RATT) to investigate time- and intensity-dependent changes in heart rate variability (HRV) at rest and during heart rate-controlled exercise in patients recovering from a stroke. Twelve patients (age 55.3 years ± 15.

Background: Arterial gas embolism (AGE) may occur while breathing compressed air and failing to exhale during ascent to compensate for gas expansion as pressure decreases. Trauma to the lungs from over-pressurization may result in air bubbles entering the pulmonary veins and subsequently the systemic circulation, causing obstructed blood flow and inflammatory cascades. AGEs are known to always manifest within 10 min of surfacing from depth.

Background: Syncope is a common medical condition. The reflex or neurally mediated syncope (NMS) is the most frequent type. The tilt table test (TTT) helps distinguish syncope from other common causes of complete loss of consciousness, such as epilepsy, define syncope subtypes and guide management.

The head-up tilt (HUT) test assesses both cardiovascular autonomic regulation and cerebral autoregulation. This exploratory study examined age-related changes in cardiovascular and cerebrovascular responses during the HUT test in three healthy cohorts (young, middle-aged, and elderly). We recruited 2342 neurologist-diagnosed 'normal' individuals from 18 June 2014 to 25 February 2022.
