Decrease of non-responder rate is the main challenge in cardiac resynchronization therapy. The problem could be solved, partly, in the follow-up by consequent individualization of hemodynamic pacing parameters. The esophageal electrogram feature of the Biotronik ICS 3000 programmer was used in the follow-up of 20 heart failure patients carrying implants for cardiac resynchronization therapy. Adverse hemodynamic programming of the sensed and paced AV delay could be easily observed and replaced
