Manucripts submitted for evaluation in the Journal of Cardiac Arrhythmias should consist of themes related to pacemakers, arrhythmias, and related areas and will only be published if approved based on their originality, significance, and scientific contribution. Manuscripts must be submitted electronically by the link: https://jca.org.br. If the authors have not yet registered, it is necessary to do so before submitting the work, following the guidelines that appear on the website. The texts must be edited in Microsoft Word, and the figures, photos, tables, and illustrations must have a jpeg extension and a minimum resolution of 300 dpi. If the work has already been presented at a congress, the title of the congress, place, and date of presentation must be mentioned, and the author must obtain authorization for publication if the congress holds the copyright on the work. The Journal of Cardiac Arrhythmias supports the clinical trial registration policies of the World Health Organization (WHO) and the International Committee of Medical Journal Editors (ICMJE), recognizing the importance of these initiatives for the registration and international dissemination of information on clinical trials in open access. Therefore, it will only be accepted for publication, from 2008, clinical trial articles that have received identification number in one of the Clinical Trial Registries validated by the criteria established by WHO and ICMJE, whose addresses are available on the ICMJE website (http://www.icmje.org/). The identification number should be recorded at the end of the abstract. All works sent to the Journal of Cardiac Arrhythmias will be submitted to peer review by at least three referees who will respond to a questionnaire in which they will classify the manuscript, their rigorous appreciation in all items that should compose a scientific work, noting each of these. In the end, they will make general comments about the work and will inform if it should be published, corrected according to the recommendations or rejected definitively. Once they have obtained these details, the publisher will make the decision. In case of discrepancies between the evaluators, a new opinion may be requested for a better judgment. When modifications are suggested, they will be forwarded to the lead author and then to the reviewers to see if the requirements have been met. After editing, the manuscripts will be sent to the author that can verify that there are no errors. The manuscripts can be written in Portuguese, Spanish, or English, with the current spelling. The editorial team will provide a translation of articles received in Portuguese into English, and both versions will be published on the Journal of Cardiac Arrhythmias website. Authors should mention in the "Methods" section whether the research ethics committee approved the research of the institution they belong to, according to the Declaration of Helsinki (http://www.ufrgs.br/bioetica/helsin5.htm). In experimental animal studies, the norms established in the Guide for the Care and Use of Laboratory Animals (Institute of Laboratory Animal Resources, National Academy of Sciences, Washington, D.C., 1996) and the ethical principles in animal experimentation of the Brazilian College of Animal Experimentation (COBEA) must be respected (www.cobea.org.br/). The manuscripts must obligatorily contain the following sections: a) title in Portuguese and English; b) full name and ORCID of the authors; c) institutional affiliation of all authors with up to three instances; d) city, state, and country; e) abstracts in Portuguese and English with a maximum of 250 words in original articles and 100 in case reports. The abstract should be structured into four sections: objective, methods, results, and conclusion. Abbreviations should be avoided. In the case of reports, the abstract should be unstructured (informative or free). The same for the abstract. Also, three to five descriptors (keywords) should be included, as well as their translation for keywords (descriptors). The descriptors have to be consulted at http://desc.bvs.br/ for terms in Portuguese, Spanish and English or www.nlm.nih/gov/mesh for terms in English only. The text should be structured with the sections: a) introduction; b) method; c) results; d) discussion; e) appreciation; f) contribution of each author; (g) funding agencies; and (h) a list of references. The name of the corresponding author with e-mail must be defined. Tables and figures should be numbered in order of appearance in the text and contain a title. Tables should not contain redundant data already quoted in the text. The Journal of Cardiac Arrhythmias adopts the Vancouver Standards - Uniform Requirements for Manuscripts Submitted to Biomedical Journals organized by the International Committee of Medical Journal Editors - Vancouver Group (www.icmje.org). Thus, references must be numbered sequentially as they appear in the text. Personal communications and unpublished data should not be included in the list of references but only mentioned in the text and footnote on the page where it is mentioned. Cite all authors of the work if they are six or less or only the first six followed by et al. if there are more than six. The abbreviations of the journals must conform to Index Medicus/MEDLINE. The Vancouver Convention sets that duplicate articles in the same or another language, especially in different countries, may be justifiable and even beneficial. Thus, articles published by Brazilian authors in scientific journals from other countries may be accepted if the editor considers relevance and necessity. In a footnote on the first page of the second version should inform the readers and researchers that the article was published in full or in part and present the reference of the first publication. The note should contain "This article is based on a study previously published in (the title of the journal with complete reference)."
