Abstract

In a series of 35 consecutive patients, the presence of a permanent pacemaker appears to be a strong risk factor for developing superior vena cava syndrome after radiofrequency modification of the sinus node. Treatment of this complication with balloon venoplasty is as effective as surgical repair.
