为分析室性早搏(VPBs),以动态心电图(DCG)监测169例老年人(包括健康者及心脏病者),并以老年前期158例作对照。发现老年期心脏病者频发VPBs(≥100/24h)检出率高于健康者;老年前期频发及复杂VPBs检出率心脏病者高于健康者;心脏病者老年前期复杂VPBs及Ⅴ级VPBs检出率均高于老年期;健康者老年前期VPBs情况与老年期相比则差别不著。还发现健康者VPBs数并无昼夜之差。并讨论了上述结果的可能机制及临床意义。
To analyze ventricular premature beats (VPBs), 169 elderly people (including healthy and heart disease) were monitored by dynamic electrocardiogram (DCG), and 158 were used as controls in the pre-senile period. Found that the detection rate of frequent VPBs (≥100 / 24h) in elderly patients with heart disease was higher than that in healthy subjects; the detection rate of frequent and complicated VPBs in elderly pre-elderly patients with heart disease was higher than that in healthy people; heart disease was complicated VPBs and Ⅴ Grade VPBs were higher than the detection rate of the elderly; healthy pre-elderly VPBs compared with the elderly are not the difference. Also found that the number of healthy people VPBs no difference between day and night. And discussed the possible mechanism and clinical significance of the above results.
