A cardiac rhythm management device capable of delivering multiple uni-chamber stimulation pulses to a patient's heart and suitable for verifying capture independently for each uni-chamber stimulation pulse. The uni-chamber capture verification mode of the cardiac rhythm management device may be activated via telemetry or by applying a magnetic field proximate the device. During the capture verification mode, bi-chamber pacing, for example, may precede or follow uni-chamber pacing to allow for pacing support. Also, the energy levels of the pacing stimulus over several beats may be varied, thereby verifying the programmed safety margins.
