what is the success rate for a cardio version
"As mentioned above, cardioversion is useful for terminating arrhythmias that arise from a reentry circuit. Cardioversion is tailored for each type of arrhythmia.
Atrial fibrillation — Atrial fibrillation (AF) is a common arrhythmia that may be treated with cardioversion.
The success rate of cardioversion with atrial fibrillation is generally better than 90 percent. Chances of success are lower when the atrial fibrillation has been present for more than several months or when the left atrium is very enlarged.
In general, there are two ways that a cardioversion procedure for AF can fail. In some cases, the energy required to restore the heart to a normal rhythm is higher than the maximum energy that can be delivered by the cardioversion equipment. When this occurs, newer generation equipment that can deliver a more effective type of energy waveform, known as a biphasic waveform, can be used if it was not used initially. Almost all hospitals now have defibrillators that deliver biphasic waveforms. Other potential solutions include applying pressure to the paddles during the shock, and administration of an intravenous medication called ibutilide. Ibutilide lowers the energy required to restore the heart to a normal rhythm and is highly effective in patients who can safely received the medication. When this drug is given, patients must be monitored for at least four hours before going home."
The big question is what is the plan to keep you in NSR after the cardioversion.
