Ventrikular Takikardia Refrakter Pada STEMI & Stroke
Get PDFPasien STEMI memiliki resiko 4 kali lebih tinggi untuk mengalami aritmia ventrikel yang umumnya terjadi dalam 48 jam pertama setelah onset. Dengan kondisi penyakit penyerta berupa stroke dengan skor severitas berat atau stroke hemoragik, intervensi koroner perkutan (IKP) atau pemberian obat - obatan anti trombotik tidak dapat dilakukan pada fase - fase awal. Optimalisasi obat - obatan anti-iskemik dan anti-aritmia menjadi strategi utama. Aritmia sendiri cukup sering dijumpai selama fase akut stroke, namun mekanisme aritmia ventrikel pada sindroma koroner akut (SKA) dan fase akut stroke masih diperdebatkan. Terlalu absurd jika hanya memikirkan kelainan jantung sebagai penyebab aritmia, mengabaikan kejadian neurologis yang juga sedang terjadi. Beberapa penelitian menunjukkan STEMI & stroke akut dapat memicu timbulnya aritmia ventrikel melalui mekanisme yang berbeda. Laporan Kasus ini dibuat untuk memberikan contoh praktikal dari ilustrasi diatas. Pada kasus ini pasien memiliki 2 entitas penyakit akut disaat bersamaan, yakni STEMI dan stroke. Pasien juga mengalami aritmia ventrikular yang refrakter. Pada akhirnya, dapat ditarik kesimpulan bahwa aritmia yang timbul bukan hanya diakibatkan oleh kelainan kardiovaskular semata, yang lebih umum dipahami, tetapi juga sebagai komplikasi dari kelainan akut neurologis. Diperlukan penanganan multi-disiplin ilmu dan komperhensif untuk optimalisasi manajemen pasien ini
PERANAN ELEKTROKARDIOGRAFI PADA HIPERTROFI VENTRIKEL KIRI
Get PDFHipertensi merupakan massalah kesehatan global dan faktor risiko utama morbiditas dan mortalitas penyakit kardiovaskular (PKV). Pemeriksaan baku emas untuk mendiagnosis HVK adalah dengan menggunakan ekokardiografi dan magnetic resonance imaging (MRI). Tidak semua fasilitas kesehatan mampu melakukan pemeriksaan ini dan mahal. Elektrokardiografi (EKG) merupakan pemeriksaan yang dimiliki hampir di semua fasilitas kesehatan. Pemeriksaan ini murah dan mudah untuk digunakan. tahun 2009, American Heart Association/American College Cardiology Fondation/Heart Rhythm Study (AHA/ACCF/HRS) mengeluarkan daftar 36 kriteria EKG untuk diagnosis HVK namun sensitivitasnya relative rendah. Tinjauan pustaka ini bertujuan untuk menjelaskan peranan EKG untuk memprediksi hipertrofi ventrikel kiri khususnya pada hipertensi
Perbedaan Akurasi Elektrokardiografi Menurut Kriteria Peguero-Lo Presti Dan Kriteria Tradisional Dalam Diagnosis Geometri Ventrikel Kiri Abnormal Pada Pasien Hipertensi
Get PDFLatar Belakang: Pola geometri ventrikel kiri (VK) adalah pola dimensi ventrikel berdasarkan diameter ruang dan ketebalan dinding. Kedua parameter ini merupakan ekspresi peningkatan beban kardiovaskular secara struktur akibat hipertensi. Ekokardiografi masih merupakan pemeriksaan baku emas, tetapi belum dapat digunakan di semua fasilitas pelayanan kesehatan. Beberapa kriteria elektrokardiografi (EKG) seperti Kriteria Peguero-Lo Presti (PLP) atau kriteria tradisional diduga dapat dijadikan untuk menilai abnormalitas geometri VK dan hipertrofi ventrikel kiri (HVK).
Metode Penelitian: Penelitian ini bersifat retrospektif, observasional analitik dengan desain kasus kontrol, dan dilakukan di Instalasi Pelayanan Jantung Terpadu (IPJT) RSUP Dr M Djamil Padang dari bulan September sampai dengan Desember 2019. Mesin elektrokardiografi menggunakan KENZ Cardio 601 dan ekokardiografi menggunakan Phillips Epic 7. Parameter EKG diukur menggunakan kaliper digital Krisbow KW06-351. Semua data diolah menggunakan SPSS 25
Hasil Penelitian: Geometri VK abnormal menurut Kriteria Peguero-Lo Presti mempunyai sensitivitas 42,1%, spesifisitas 96,1%, NPV 62,6% dan PPV 91,4% dengan akurasi 69,2%, AUC 74,5%. Dalam hal mendiagnosis HVK, kriteria PLP mempunyai sensitivitas 47,5% dan spesifisitas 92,8%, nilai prediksi negative 73,4% dan nilai prediksi positif 80,8%.
Kesimpulan : Kriteria Peguero-Lo Presti mempunyai akurasi yang lebih baik dibanding kriteria tradisional dalam hal mendiagnosis Geometri VK abnormal dan HVK pada pasien hipertensi
Kata Kunci : Kriteria Peguero-Lo Presti, kriteria elektrokardiografi, hipertrofi ventrikel kiri, geometri ventrikel kir
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
