Researchers have studied the effect of CRT on cardiac remodeling in HF using a canine model of HF with 3 to 4 weeks of 240 bpm right ventricular pacing and left-ventricular diastolic end pressure of 30 to 45 mm Hg. Electrical changes included prolonged action potential duration, a hallmark of HF, and increased difference between the longest and shortest action potentials at slower rates.</style></abstract><number><style face="normal" font="default" size="100%">3</style></number><volume><style face="normal" font="default" size="100%">12</style></volume></record></records></xml>
