Cardiac resynchronization therapy is a well-established treatment of heart failure with reduced left ventricular ejection fraction and a wide QRS complex. Cardiac contractility modulation therapy is an emerging electrical treatment indicated for use in patients with symptomatic heart failure caused by moderate-to-severe systolic left ventricular dysfunction (left ventricular ejection fraction ranging from 25% to 45%), with no indication for cardiac resynchronization therapy. Cardiac contractility modulation therapy improves functional status, exercise capacity, quality of life, and possibly prevents hospital admissions in indicated patients. An algorithm for patient selection for these two forms of electrical therapy for heart failure is presented.
心脏再同步治疗是一种成熟的心力衰竭治疗方法，适用于左心室射血分数降低和宽 QRS 复合物的心力衰竭患者。心脏收缩力调节治疗是一种新兴的电治疗方法，适用于由中度至重度收缩性左心室功能障碍（左心室射血分数在 25%至 45%之间）引起的有症状心力衰竭且不适合心脏再同步治疗的患者。心脏收缩力调节治疗可改善患者的功能状态、运动能力、生活质量，并可能预防有适应证的患者住院。本文提出了这两种心力衰竭电治疗方法的患者选择算法。
