摘要：
Embodiments of the present invention concern the timing of sending one or more commands to control circuitry of a multi-electrode lead (MEL). In one embodiment, the one or more commands are sent to control circuitry within the MEL during a predetermined portion of a cardiac pacing cycle to avoid potential problems of prior systems that were not synchronized with the cardiac pacing cycle. In one embodiment, the one or more commands are sent when cardiac tissue is refractory from a cardiac pacing pulse, to prevent the command(s) from potentially undesirably stimulating cardiac tissue. The command sending can occur such that the one or more commands are sent between instances when sensing circuitry of the implantable cardiac stimulation device is being used to obtain one or more signals indicative of cardiac electrical activity, to prevent interference between the one or more commands with the signals indicative of cardiac electrical activity that are sensed.
