Doctor insights on:
Single dose: Adenosine is given as a single dose that may be repeated once. It is extremely short acting but has side effects. You may feel short of breath, hot and flushed, nauseated, dizzy, get a headache, have chest pain, or feel like you're going to have diarrhea. The side effects all improve in about 1 minute and generally are gone in ...Read more

Rash and skin reacti: Allergic reaction are different then side effect. Skin reactions and rash are the most common. Wheezing and shortness of breath are side effects and could've serious.

What medication does the ER administer during a severe episode of SVT caused by WPW syndrome? Adenosine is contradicted with WPW right?
WPW: Procainamide (pronestyl) given intravenously has been successfully used in such cases. Adenosine can be given as long as the qrs is narrow. Electric cardioversion can also be performed. Beta blockers can also be tried iv. In my experience, procainamide has been quite effective although it is an older medication. Ideally a cardiologist would be available to treat such a patient. ...Read more

No interaction..: Not sure if this is what you meant to ask. But there is no known interaction between the two medicines. Also, the half-life (time it takes for half to disappear) of Adenosine is less than 10 seconds and thus not likely to cause much problem even if it does. Adenosine is usually given via IV push hoping to correct a specific heart arrythmia n it is gone in seconds/minutes. Ask again if u need to.. ...Read more
Cardiac arrhythmias?: I assume you're asking about cardiac arrhythmias? Lidocaine affects ventricular ectopy and has no effect on av conduction. It's was used for ventricular tachycardia and has largely been supplanted by amiodarone. Adenosine has no effect on the ventricles. It blocks av conduction. It's used to terminate supraventricular tachycardias. ...Read more

Mitochondria: Rare genetic mitochondrial diseases can result in defects in ATP synthesis, resulting in muscle weakness and other symptoms. Nutritional supplements have been tried and some people think they help but there is very little evidence for this treatment. A good source of info is at http://www. Mda.

MPS: I believe you are referring to a myocardial perfusion scan, where technitium sestamibi 99 is the radioactive isotope that is injected intravenously so that images can can be taken of the heart at rest and 'stressed' or exercrsing -which brings us to the adenosine: a pharmacological agent used to 'stress' the heart instead of walking on a treadmill. Lexiscan is the stress agent of choice now. ...Read more
Local: Adenosine has a very short half life (only a few seconds). It is not in that sense a "circulating hormone". It's effects are mainly local and produced by cells, including heart muscle. It's production increases when there is need for increased circulation and blood flow to the heart, such as physical stress. ...Read more

I'm having an MRI adenosine stress test for my heart. Should I be worried about the risks? How often do you see serious problems with this?
MRI stress test: As long as he will kidney function, lung function and ECG conduction are reasonable there should be very minimal worry of bad effects, adenosine can cause transient breathlessness, headache, abdominal distress typically self limiting for a few minutes. Check with the ordering physician if you should hold your diltiazem. Good luck ...Read more
If adenosine help to treat heart issues, why was it used to "stress" my heart during cardiac MRA?
Different doses: Adenosine dilates blood vessels (which is the basis of its use for stress testing - it can show a "steal" away from a blocked artery) and it slows conduction thru the AV node (the basis of terminating certain arrhythmias). Beyond those 2 uses, it doesn't otherwise "treat heart issues". ...Read more
Adenosine In ER for emergency treatment of severe SVT episode. Could it not work and/or cause cardiac arrest/death?
Adenosine is useful: For the treatment of a certain type of SVT but not all SVTs. In addition, it is not always affective with an initial dose and requires second higher doses to be administered. It is unlikely but not impossible to cause cardiac arrest and/or death. Most SVTs are curable by radio frequency ablation in the hands of a qualified Electrophysiologist. Make an appointment for evaluation. ...Read more
How to choose the best hospital and the best cardiac electrophysiologist in nyc for cardiac ablation is the procedure ever life threatening? I do get SVT 4-5 times a year and have to go to the hospital for an adenosine shot. Is this procedure life threat
Hard. And no.: Svt is never fatal (with ultra-rare exceptions you almost certainly don't have) and is treated for symptoms. You're wise to look for someone good, but it isn't always easy to find the top folks. I can give you some names, but I won't do it in broad forum; to do so would be an insult to the many other excellent eps also in the area. Nyc is awash in excellent ep and you have several options. ...Read more

There are none...: Even the strongest opiates only "take the edge off" for people in chronic pain. Meds are only one part of dealing with the pain. A useful tool, but pain is so necessary for survival that we are not "allowed" to monkey with it much. In acute pain, the transition from miserable to less miserable can be great. In chronic pain, it's just part of the plan. ...Read more
