After NO-synthase inhibition, the hypotensive response induced by OEMV was attenuated significantly as compared to control; however, the bradycardic
effect of OEMV was not changed (Fig.
One ETT was replaced following intubation due to a suspected leaking cuff--this polytrauma patient became bradycardic
following positive pressure ventilation; paramedics instituted two minutes of cardiopulmonary resuscitation, and began an adrenaline infusion before handing the patient over to helicopter staff.
The reflex bradycardic
sensitivity was also significantly higher in TH than SH (p < 0.
Ten minutes into the procedure the pulse oximetry readings decreased from 96 to 80%, and the patient became profoundly hypotensive (40/25 mmHg) and bradycardic
On examination he was afebrile, hypertensive (blood pressure of 189/78 mm Hg), bradycardic
(heart rate of 46 beats per minute) with a normal respiratory rate (20 breaths per minute), and had a normal arterial oxygen saturation (SpO2 of 100% on 2 L/min nasal cannula).
and hypothermic effects of perfluoro-n-decanoic acid in rats.
The maintenance of intact ATP molecules in solution is critical for the unique bradycardic
effects of ATP, in particular its blockade of atrio-ventricular nodal conduction.
Soon after, the patient became significantly hypotensive (70/40) and bradycardic
with a heart rate in the 30s.
Upon arrival to the NTSICU, the patient's GCS score was 5 (1 = eye opening, 1 = verbal, 3 = motor) and he was becoming more bradycardic
, from 45-55 beats per minute.
The experiments of the hemodynamic effect of isoproterenol after pretreatment with the triterpenoids, pointed out that the vasodepressor and bradycardic
effects of the test compounds may be due to [beta]-blocking activity, similar but less potent to that of propranolol.
New directions in antiarrhythmic therapy being explored for AF include novel formulations of class I antiarrhythmic agents, coupling agents that act upon connexins, specific bradycardic
agents, and serotonin receptor antagonists.
Experimental studies using l(f) channel blockers, which have pure bradycardic
effects, have shown different results, according to the HF model used, and the clinical effects of long-term HR altering on HF are unknown (6).
