Hi, CardiologyForum.ORG ( http://cardiologyforum.org ) is an exclusive next generation social networking service for Cardiologists & CardioSurgeons....
I may have asked this a long while back, but.. I am trying to understand how Amiodarone does what it does. Is the intention of prolonging deploarization to...
Hey Jon, Great question... I am getting rusty on pharmaceuticals but here goes... amiodarone is in a class of sodium channel blockers. Sodium is moved in and ...
Nick, Wow this is making me think back into the fuzzy gray area of my brain..... I was under the impression that the sodium-potassium pump works in only one...
Hey Brian, We could compare fuzziness... think of the transmembrane potentials as being a magnet (think North and South or Positive and Negative). First the...
This is working from memory as well. But that is my impression also. In phase 0 the sodium channels open allowing sodium to move into the cell via their...
Robert, I agree with your explanation more than with Nick's, although this may be do to my interpretation of Nicks description, not his knowledge! Nick are you...
Ok I went to THE source for all things worth knowing: http://en.wikipedia.org/wiki/Amiodarone and http://en.wikipedia.org/wiki/Cardiac_action_potential In a...
Today's NEJM has a great review article on thrombus formation. I've heard electrophysiologists, interventional cardiologists, and others in industry with...
I would like a copy. The link requires membership dd From: ekg_club@yahoogroups.com [mailto:ekg_club@yahoogroups.com] On Behalf Of Nikiah Nudell Sent:...
Hi Nick! Â If you could forward me a copy of the article that would be great. We now have our 12 lead program in service, this would be a good teaching tool. ...
I too would appreciate a copy if possible. Thanks ... -- Harvey Conner, AS, NREMT-P Chairman, Oklahoma Regional ECC Committee Professor of EMS Oklahoma City...
Tried to send a pdf of the article to this list, but wonderful yahoo groups is rejecting. Although I can certainly send to anyone directly if you contact me...
Nick, Â I would like a copy of it for our training program. It sounds like an informative piece. Â Thanks, Thom Seeber, CCEMT-P CES Manager, South Divison ...
Another nice summary from Wilkipedia.....  http://en.wikipedia.org/wiki/Antiarrhythmic_drugs#Vaughan_Williams_antiarrhythmic_classification  ... From:...
In case anyone is interested, I think this is going to be the next great treatment out there... Â http://www.medscape.com/viewarticle/567980 Â Â Â In case...
I recently had an interesting conversation with a true expert in cardiac signal measurement and think this will make for interesting discussion. What causes...
My understanding of Q wave development is that the death of myocardium (transmural) causes an area that is like a window. The Positive Lead does not see a...
Q-waves aere caused by seeing the signal through electrically silent tissue. You are actually seeing the signal as it travels through normal tissue from inside...
Hi Hank, Qwave myth is busted. Although this is probably the most common explanation given, it is physiologically incorrect. Rwave myth is... I'm not sure that...
Hi Jason, Qwave myth is busted. Although this is probably the most common explanation given, it is physiologically incorrect. Rwave myth... not attempted. ;-)...
Re: Q wave: isn't the vector still heading the same direction, even if passing "through" dead tissue? Thus, it would still generate a positive deflection (if...
Hi Jon, The cause is actually at a level much smaller than the overall vector. That is a hint, so I'll give folks a little more time to think... Any cerebral...
R-wave progression is easy to understand. The limb leads form a frontal plane hexial system. The normal QRS vector in this plane is down and to the left. The...
