摘要
并行心律的诊断标准存在下列问题：１．融合波无特异性，敏感性不高，本组８７例并行心律中出现率仅４５％。２．联律间期相差（＞０．０８ｓ）与不等（≤０．０８ｓ）的标准有界无距，难免误差。本组病例联律间期相差皆≥０．１１ｓ。３．各早搏间期是异位周期长度的整倍数，这一条有不少偶然因素可以造成，如异位心律与基本心律的周期长度近似或两者有数字上的巧合。上述缺陷，使并行心律的诊断标准必须重订。
The defects of the diagnostic criteria of parasystole are as follows : 1.The fusion beats not only lack of specificity but also show a lower sensitivity. The fu-sion beats appear only 45% in eighty-seven patients with parasystole observed. 2.There exists a boudary but not a distance in time with the criterion of difference of cou-pling intervals between unequality (>0. 08 s) and equality (0.08 s). So errors arehard to avoid. The differences of coupling interval in this group patients are all 0. 11s. 3. All the intervals of inter-premature beats are exactly multiple of a ectopic cyclelength. The criterion may be satisfied while the ectopic rhythm and the basic rhythmhave close cycle lengths or exist numeral coincidence. For the above-mentioned defects,the diagnostic criteria of parasystole wait for further revision.
