1. A device for providing stimulating pulses to the heart above and below a stimulation threshold, comprising:
- first and second electrodes adapted to be implanted in the heart, a sensor configured to detect atrial fibrillation;
a processing unit in electrical communication with the first and second electrodes and the sensor, the processing unit being configured to provide first electrical stimulation pulses above the stimulation threshold to the first electrode and second electrical stimulation pulses below the stimulation threshold to the second electrode, the second electrical stimulation pulses being provided in response to a detection of atrial fibrillation.

Abstract
Electrodes can generate electrical stimulation pulses at least one first intensity level and at least one second intensity level. The first and second intensity levels are above and below a given stimulation threshold, respectively. The synchronous or asynchronous delivery of second-level pulses enables the conduction of the atrioventricular node to be modulated by electrotonic effect, for example, to reduce ventricular frequency in the event of atrial fibrillation.
