Median HRPO was <100 bpm the first 2 min after which it rapidly increased. HRECG remained stable at 150–160 bpm (table).ConclusionHR measured by PO is significantly lower compared to ECG, which has important implications for clinical care in the first minutes after birth....

Heart rates (HRs) vary considerably, not only with exercise and fitness levels, but also with age. Newborn resting HRs may be 120 bpm. HR gradually decreases until young adulthood and then gradually increases again with age. Maximum HRs are normally in the range of 200–220 bpm, although t...
9. 心率(heart rate: HR) 心率储备(heart rate reserve)是指最大运动后心率的可增加程度,心率储备=最大预测心率﹣最大运动时测得的心率,最大预测心率=220﹣年龄(岁)或者=210﹣0.65×年龄(岁)。HHR对不同疾病的诊断有帮助,正常情况下,HRR≤15次/分,在临床症状较轻的...

查体:T36.7℃,P90bpm,R20bpm,BP135/90mmHg,神志清楚,消瘦,口唇黏膜苍白。入院后抽取血型和血交叉标本以备血,已知既往患者血型为A型RhD阳性。患者在输注血液制品过程中,突然出现皮肤瘙痒,单纯荨麻疹,给予抗组胺药物后,上述症状得以缓解。可能是什么原因引起的 A. 红细胞血型不合 B. 白细胞抗体 C. 血小板...
METHODS AND RESULTS: Adult dogs underwent left bundle-branch ablation and either right atrial pacing (190 to 200 bpm) for 6 weeks (DHF) or 3 weeks of right atrial pacing followed by 3 weeks of resynchronization by biventricular pacing at the same pacing rate (CRT). Isolated left...
在预测低血压时,对照组最小SBP前最大心率的AUC-ROC为0.76(95% CI. 0.59 to 0.0.93)(p=0.002)(图3)。当基于Youden指数的HR临界值为103.5次/分时,敏感性为76.9%,特异性为76.9%;当HR为85 次/分时,敏感性为100%,特异性为0%;...
