Supraventricular tachycardia (SVT), the most common sustained symptomatic arrhythmia of childhood, is often supported hy a manifest or concealed accessory pathway. Permanent interruption of the accessory pathway usually ...
Cardiac controlled release for arrhythmia therapy: Lidocaine-polyurethane matrix studies
(Elsevier, 1988-12)
Cardiac arrhythmias are the principal cause of sudden death due to heart disease, and current therapy is inadequate. A novel approach for formulating a lidocaine-polyurethane controlled release matrix and implanting this ...
