TL;DR: Ondansetron given intravenously attenuates the fall of systolic and mean blood pressure, but does not have an influence on diastolic blood pressure or heart rate.

TL;DR: It is concluded that promethazine induces significant QTc prolongation but the lack of influence on transmural dispersion of repolarisation makes the risk of its torsadogenic action very low.

TL;DR: Administration of intravenous ondansetron prior to spinal anesthesia in geriatric patients attenuates the drop in the diastolic and mean arterial pressure without substantially affecting the systolic blood pressure.

TL;DR: Reversible blockade of preganglionic sympathetic fibres to the heart, achieved by thoracic epidural anaesthesia, results in a reduction in QTcb, as well as the TDR, which may explain the anti‐arrhythmic action seen with central blockade.

TL;DR: The vagotonic action of remifentanil does not appear to be related to baseline autonomic tone in adult patients, and baseline heart rate was the only independent predictor of rem ifENTanil‐induced bradycardia.
