Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Abstract figure legend The results from this study show that maximal cardiac output, stroke volume and leg blood flow are similar between highly trained females and males after normalisation to lean body mass (LBM). However, the 10% higher haemoglobin concentration ([Hb]) and arterial O2 content in males result in higher systemic and leg O2 delivery ...

Physicians value timeliness and accuracy in choosing implantable cardiac monitoring (ICM) or tilt table testing (TTT) to investigate syncope in older patients without clues or heart disease. Europeans preferred 75% while North Americans preferred ICM 85%. 61% expressed concerns about missed diagnoses with TTT and only 19% for ICM.

Microelectrode recordings from the human cervical vagus nerve during maximal breath‐holds
Abstract Voluntary breath‐holds can be sustained for a long time following training, but ultimately, regardless of duration, the asphyxic break‐point is reached and the apnoea terminated. The physiological changes occurring during the apnoea include a marked increase in sympathetically‐mediated vasoconstriction in non‐essential organs, such as skeletal
