Abstract
Management of the patient without inducible arrhythmias is dictated by the clinical setting in which the arrhythmias occur. Decisions must be based on whether the patient is being treated for symptomatic arrhythmias, or is undergoing evaluation of risk for potentially lethal arrhythmias. The management is influenced by the anatomic substrate, as well as the clinical presentation. As with all diagnostic tests, the significance of the electrophysiology study depends on the clinical context, and this type of test reflects but one mechanism for tachycardia. Finally, it is critical to remember that the results of published clinical trials can be used to guide management decisions, only when the same stimulation protocol utilized in the trials is employed, and the patient has the same characteristics as those enrolled in the trial.

I did not have that information when I answered, but this is a complex case because arrhythmias have many causes.

The patient was cured. Again, this is new territory for me, but it looks like they're talking about radioablation to treat cardiac arrhythmias ... http://my.clevelandclinic.org/heart/services/tests/procedure...

And after the treatment, if "the patient is noninducible", it means that the arrhythmia has been successfully treated. The arrhythmia can't be produced/induced when the cardiologist tests the outcome of the procedure.

En otras palabras: "Una vez realizada la ablación de las células defectuosas, el médico intenta inducir o provocar de nuevo la arritmia. Si no es posible inducir la arritmia, la ablación produjo el efecto deseado. Pero si la arritmia comienza de nuevo, es probable que sea necesaria una ablación adicional.

Procedures "The patient underwent electrophysiology study and radiofrequency ablation of all 4 pulmonary veins, the posterior wall of the left atrium and fractionated electrograms along the left atrial septum. The superior vena cava was isolated. Electrograms were mapped to the left atrial septum and the base of the left atrial appendage, and radiofrequency energy was applied with elimination of potentials. At the end of the case, the patient was noninducible for arrhytmia

Thanks I didn't think they would try to induce arrhythmia in a patient. Let me check to give you more context

Joseph Tein Sep 26, 2011:

More context? Hi Yvonne,

For me (with limited knowledge of cardiology), more context of the patient's history and condition, and any procedures performed would help. However, I think that -- in this awkward English -- it means that cardiac arrhythmia could not be induced, could not be made to appear. Sometimes during a diagnostic procedure, it seems that the physicians try to deliberately induce arrhythmia in a patient -- see: http://europace.oxfordjournals.org/content/early/2011/07/14/...

¡Espero que ayude a tu compañera!
