Comparing two different protocols for tilt table testing: sublingual glyceryl trinitrate versus isoprenaline infusion.
OBJECTIVE To assess the diagnostic value and safety of sublingual glyceryl trinitrate tilt testing compared with isoprenaline infusion in patients with unexplained syncope. DESIGN Glyceryl trinitrate and isoprenaline tilt tests were performed in two successive days on a random basis in cases and controls. SETTING Outpatient cases with syncope referred to Shahid Rajaii Heart Hospital. SUBJ...

متن کاملAdministering a glyceryl trinitrate infusion: big is not always best.
With the use of some simple calculations it can be demonstrated that the choice of cannula and initial glyceryl trinitrate (GTN) infusion rate for patients with acute left ventricular failure (LVF) requires some careful thought. If a GTN infusion is commenced at a rate of 1 ml/h, a critically unwell patient with a large cannula--for example, a grey cannula--will have to wait over 6 min for the ...
متن کاملComparison with glyceryl trinitrate
The coronary haemodynamic effects of nifedipine and glyceryl trinitrate were compared in 22 patients undergoing investigations for suspected coronary artery disease. Myocardial blood flow was estimated by the coronary sinus thermodilution technique. In sinus rhythm nifedipine increased mean coronary sinus flow from 135 ml/min to 152 m/min, and reduced arterio-coronary sinus oxygen difference fr...
