The long-term effect of pacemakers in the management of bradycardic heart failure with or without syncope was tested on 337 patients. The cumulative survival rate of patients with Adams-Stokes attacks without heart failure (group I) was 91% at the end of one year, 73% at the end of three and 35% at the end of eight years. Among patients with Adams-Stokes attacks and accompanying heart failure (group II) 81% survived one year, 64% three and 46% five years, but only 25% eight years. Among patients in whom heart failure was the only indication for pacemaker implantation (group III), 70% were still alive after one year, 56% after three and 17% after five years. Related to the severity of heart failure before and after pacemaker implantation, most of the patients of group II (mild or moderately severe failure) had definite improvement, while of those in group III (mainly severe failure) only about half had less cardiac failure. In patients with severe heart failure and bradycardia (without syncope) long-term results are not likely to be very good, as regards both duration of survival and physical capacity.
对337例患者进行了起搏器治疗伴或不伴晕厥的缓慢性心力衰竭的长期疗效测试。无心力衰竭的阿-斯发作患者（第一组）的累积生存率在1年末为91%，3年末为73%，8年末为35%。伴有阿-斯发作和心力衰竭的患者（第二组）中，81%存活1年，64%存活3年，46%存活5年，但8年末仅25%存活。在因心力衰竭是植入起搏器唯一指征的患者（第三组）中，1年末70%仍存活，3年末56%仍存活，5年末17%仍存活。与起搏器植入前后心力衰竭的严重程度相关，第二组（轻度或中度严重心力衰竭）的大多数患者有明确改善，而第三组（主要是严重心力衰竭）中只有约一半患者心力衰竭减轻。对于严重心力衰竭和心动过缓（无晕厥）的患者，就生存时间和身体能力而言，长期结果不太可能很好。
