Five patients are reported, admitted to the hospital, with diseases predominantly of the cardio-vascular system. During the electrocardiographic examinations bundle branch block was established, depending on heart rate. It fluctuated within the physiological limits from 50 to 90/min. In three of the patients, the bundle branch block appeared with the quickening of the heart rate (tachycardia-depending bundle branch block) and in two of the patients--the bundle branch block appeared during the slowing down of the heart action and disappeared with its quickening (bradicardia-depending bundle branch block). A brief literature review is presented and attention is paid to the possible diagnostic errors and the treatment mode of those patients with cardiac tonic and antiarrhythmic medicaments.
本文报告了5例主要患有心血管系统疾病并入院治疗的患者。在心电图检查过程中，根据心率确定存在束支传导阻滞。心率在50至90次/分钟的生理范围内波动。其中3例患者的束支传导阻滞随着心率加快而出现（心动过速依赖性束支传导阻滞），2例患者的束支传导阻滞在心率减慢时出现，并随着心率加快而消失（心动过缓依赖性束支传导阻滞）。本文还进行了简要的文献综述，并关注了这些患者使用强心和抗心律失常药物时可能出现的诊断错误及治疗方式。
