Official Title: Double-Blind, Randomized, Single-Dose Study to Evaluate the Atrial Selectivity and Safety of BMS-394136 in Patients With Implanted Dual-Chamber Pacemakers or Defibrillators

Further study details as provided by Bristol-Myers Squibb:

Primary Outcome Measures:
  • Effect of BMS-394136 on atrial refractoriness (atrial effective refractory period)
