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

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

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.

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
