I am a clinical electrophysiologist and visited Washington University for 1 year. Remarkable advances of diverse therapeutic modalities in fields of electrophysiology have been made over the past decade. Various arrhythmic diseases including Atrial Fibrillation, Paroxysmal Supraventricular Tachycardia, Ventricular Tachycardia and Ventricular Fibrillation are now treatable with catheter ablation or implantable devices, rather than pharmacological agents. Currently, our clinical electrophysiologists are making multiple ablation lines on the heart with new technology until the arrhythmia disappears. Aren’t we simultaneously creating substrate of another arrhythmia? The electrical shocks that devices deliver stop arrhythmias, yet simultaneously often bring unintended hazardous consequences, such as heart failure aggravation and increased mortality, in addition to infection. Ironically, our struggle to conquer arrhythmias often gives another new assignment to us. Our attempts to maximize omnipotent-like device/ablation technology are now threatening ourselves. What therapeutic strategy should we head to? One possible solution would be to head to the “minimization” strategy. Will minimal pacing (already tried), minimal ablation, minimal shock, invisible wire, and minimal device be new solution to release from our distress? My research focused on the relationship of sinus exit pathways and sinus node, and the new minimized treatment for sinus node-related diseases.
