Vagal Maneuvers in SVT: Give ’em a Leg Clinical development success rates for investigational drugs pdf! ED, and how effective are vagal maneuvers in converting SVT to normal sinus rhythm? SVT can be broken down both by site of origin and regularity.
Regular rhythm tachycardias originating from the atria include sinus tachycardia, atrial tachycardia, atrial flutter, and sinus node reentrant tachycardia. People with pre-existing heart disease, such as CHF or CAD, have increased chance of SVT as both ischemia and stretching of the myocardium increase the risk of arrhythmias. Seventy-five percent of patients with SVT are female. When patients present with new palpitations and tachycardia, the first step is to determine stability. If the patient is hypotensive, they need to be treated with synchronized cardioversion immediately. If the patient remains normotensive, with or without the above mentioned symptoms, he or she can be initially treated with vagal maneuvers, as they are less invasive and cause less discomfort than chemical or electrical cardioversion. A second vagal maneuver is ice water immersion of the face, which stimulates the human diving reflex and acts via the vagal nerve as well to slow heart rate.
Its efficacy negatively correlates with increasing age. There are multiple variations on the Valsalva maneuver, all of which attempt to increase intrathoracic pressure and causing vagal stimulation. This can be as simple as telling a patient to “bear down” as if they are having a bowel movement, having them blow into a straw or syringe, or forcefully cough. The 2015 REVERT trial represents biggest recent update in the world of Valsalva literature. BET 2: ICE WATER IMMERSION, OTHER VAGAL MANOEUVRES OR ADENOSINE FOR SVT IN CHILDREN.

Thank you to all who attended our inaugural EM Social Justice book club on August 2, 2017. For those of you who didn’t have time to read the book, or read it and could not attend, here are some of the highlights from our discussion. Evicted transforms our understanding of poverty and economic exploitation while providing fresh ideas for solving one of the twenty-first-century America’s most devastating problems. To write this book, sociologist Matthew Desomond lived in a trailer park in South Milwaukee, WI for several months in 2008, and then in an apartment in north Milwaukee in 2009.
In the trailer park, most of the residents were poor and white. In the north side, most of the residents were poor and black. In our discussion, it was striking how even among neighborhoods with extreme poverty, racial segregation continued and encouraged by both landlords and the tenants themselves. This book struck a particular chord with me, as I lived in Milwaukee, WI from 2006-2010.
