POCT是体外诊断按应用场景划分的类别，特点为临床快速诊断、操作便捷、费用低廉。 心肌细胞损伤、心脏功能衰退或心血管炎症会导致细胞膜的完整性改变和通透性增加，使细胞内的物质进入外围血循环，这些可在血循环中检测到的物质被称为心脏标志物。 心脏标志物主要有3大类，具体包括心脏组织损伤类标志物、心脏功能类标志物、心血管炎症类标志物。 已知心血管类疾病（例如，心肌梗死，冠心病，心力衰竭等）均会释放标志物，根据病症类别，心脏标志物POCT检测 …

2024年3月4日 · Acute critical illness: Acute critical cases can be assessed by POCT as follows: pulse oximeter to check oxygen saturation, ECG to assess cardiac rhythm, rate, and acute ischemic changes. POC VBG can be used to assess …

The goals of this paper are a) to facilitate the efficient diagnosis of patients who present with episodes of acute chest pain in rural emergency rooms located in low-resource community hospitals, b) to systematically optimize point-of-care (POC) testing using small-world networks (SWNs) adapted to unique and challenging geographic settings, and...

POCT provides rapid turnaround of test results with the potential for fast clinical action that can improve patient outcomes compared to laboratory testing. Review the advantages of POCT and discuss the factors that are driving the expansion of POCT in modern healthcare.

2021年8月22日 · 目前临床上主要依照临床表现、标准心电图（ECG）以及心肌损伤标志物检查对AMI做出诊断。 胸痛或胸闷不适是最常见的临床表现，但有1/3以上的AMI患者，如老年人、女性和糖尿病患者等缺乏典型症状；传统心电图的诊断敏感度仅有50%，每年约有5%的病人被漏诊，当原有左束支阻滞患者发生心肌梗死时，心电图诊断困难，单次ECG对非ST段抬高的急性冠脉综合征诊断价值有限，需要连续动态监测[6]。 对于这些临床表现和心电图不典型的病人，血清学检查 …

POC test clusters encompass electrolytes (eg, K +, Ca ++), metabolites (glucose, lactate), function monitors (acid-base, hemostasis), and several biomarkers [2]. Hospital penetration of POC cardiac biomarker testing increased from 4% in …

2014年7月18日 · Point-of-care (POC) testing for cardiac markers has been advocated for many years as a way to expedite evaluation and treatment for emergency department (ED) chest pain patients. 1,2 Although it seems intuitive that POC testing should decrease the ED length of stay and improve patient care, there are limited data demonstrating this.

床旁检测 (Pointof care testing,POCT)的出现顺应了现代临床医学高效快节奏的工作方式，缩短了临床实验结果回报时间，使医生和病人能够及时获得检测结果，为病人能够得到及时治疗赢得时间。 因此现在提倡心脏标志物的床旁检测。 目前用于急性心肌梗塞（Acutemyocardial infarction ,AMI）诊断最常用的三个指标：心肌肌钙蛋白（cardiactroponins，cTn）、肌酸激酶MB (creatinekinase MB, CK-MB)和肌红蛋白（myoglobin，Mb）。

2024年7月16日 · An electrocardiogram (ECG or EKG) is a painless, non invasive test that uses electrodes on the skin to measure these small electrical changes and produces a graph showing the electrical changes over a period of time. Commonly, an ECG will use six electrodes (or leads) placed across the chest, as well as one on each arm and leg.

2024年5月14日 · When working in a fast-paced environment, it is helpful to be able to interpret a 12-lead ECG result quickly. If you’re a clinician in urgent care or an emergency department, it’s essential that you know how to identify critical findings from an ECG. Here are some practical tips for evaluating an ECG result in a streamlined process.
