Methods, systems and computer program products for cardiac pacing are provided. A defibrillation shock is applied to a heart of the patient and a pacing stimulation signal is automatically applied to the heart of the patient subsequent to termination of the delivery of the defibrillation shock. The pacing stimulation may be applied to the heart of the patient within about two seconds of termination of the defibrillation shock. The pacing stimulation signal may be applied to the heart of the patient subsequent to termination of the defibrillation shock irrespective of a characterization of electrical activity detected in the heart. The pacing stimulation may be single and/or paired pacing stimulation.
