Apparatus for controlling tachyarrhythmia confirmation in response to patient history

摘要

A method and apparatus for delivering electrical therapy to the heart are disclosed. The apparatus detects and confirms the arrhythmia. However, during confirmation, if the arrhythmia is present but not too severe, it is allowed to continue in the hope that it will spontaneously revert. The arrhythmia is reconfirmed later and, if it is still present, electrical therapy is delivered to the heart. Thus, for mild arrhythmias, electrical shock therapy is withheld for a specified time period in the hope that the arrhythmia will revert spontaneously. More severe arrhythmias which are not hemodynamically sustaining are immediately electrically shocked in an effort to revert the heart back to normal sinus rhythm. IMAGE
