Aims and Scopes

International Journal of Arrhythmia aims to introduce new clinical knowledge, basic findings, techniques and cases which are related to arrhythmias, and specific issues of interest to an international readership. In addition, the journal is dedicated to the continuous medical education of physicians.

International Journal of Arrhythmia is a peer-reviewed, open access journal that publishes original research, reviews and case reports related to diagnosis and treatment. The journal welcomes submissions of clinical and basic research related to arrhythmia.

Research and Publication Ethics (Date of enactment)

These policies are legislated to render underlying principles and directions about the role and responsibilities to secure the research ethic through academic activities. All authors are recommended to recognize that truthfulness, veracity, and accuracy are prerequisites for reliability and should observe these policies.

1. All manuscripts must comply with the research and publication ethics guidelines recommended by the International Committee of Medical Journal Editors (ICMJE) for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals (http://www.icmje.org/icmje-recommendations.pdf).

2. In all manuscripts, authors should refer to the principles embodied in the Declaration of Helsinki (http://www.wma.net/en/30publications/10policies/b3/index.html) for all investigations involving human materials and be reviewed by Institutional Biosafety Committee (IBC).

3. Animal experiments also should be reviewed by the Institutional Animal Care and Use Committees (IACUC) for the care and use of animals. Also studies with pathogens requiring a high degree of biosafety should pass a review by the Institutional Biosafety Committee (IBC).

4. If necessary, the editorial board may request copies of informed consents from human subjects in clinical studies or IRB approval documents.

5. ‘Author’ is defined as person who contributed substantial intellectual contributions to the manuscript. The substantial intellectual contribution is defined as 1) to participate in the conception and design, acquisition of data, or analysis and interpretation of data; 2) drafting the article or revising it for intellectual content; 3) final approval to be published; and 4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. All authors should meet all four criteria. The corresponding author is defined as an author who meets the four criteria and also should be available throughout the full processes and after publication. When submitting a manuscript authored by a group, the corresponding author should clearly indicate the preferred citation and identify all individual authors as well as the group name.

6. A conflict of interest may exist when an author (or the author's institution or employer) has financial or personal relationships or affiliations that could influence (or bias) the author's decisions, work, or manuscript. The corresponding author of an article can be asked to inform the Editor of the authors' potential conflicts of interest which could possibly influence their interpretation of data and all authors should clearly disclose their potential conflicts of interest before submitting the article. In particular, all sources of funding for a study should be stated explicitly. All authors must write and submit the form for disclosure of potential conflicts of interest. Otherwise, such conflicts may be financial support or private connections to pharmaceutical companies, political pressure from interest groups, or academic conflicts. All sources of funding should be declared in a section titled "Acknowledgment" at the end of the text.

7. Manuscripts under review or published by other journals will not be accepted for publication, and articles published in this journal are not allowed to be reproduced in whole or in part in any type of publication without permission of the Editorial Board. It is possible to republish manuscripts if the manuscripts satisfy the condition of secondary publication of the "Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals" (http://www.icmje.org/publishing_4overlap.html). Secondary publication for various other reasons, in the different journal, another language, especially in other countries, is justifiable and can be beneficial provided that the following conditions are met. In such instances, the author has to receive approval from the editor-in-chief of both journals. The paper for secondary publication is intended for a different group of readers; an abbreviated version could be sufficient. The secondary version faithfully reflects the data and interpretations of the primary version. The footnote on the title page of the secondary version informs readers, peers, and documenting agencies that the paper has been published in whole or in part and states the primary reference.

8. All manuscripts should be prepared in strict observation of the research and publication ethics guidelines recommended by the Council of Science Editors, International Committee of Medical Journal Editors, World Association of Medical Editors, and the Korean Association of Medical Journal Editors ("Good Publication Practice Guidelines for Medical Journals" http://kamje.or.kr/intro.php?body=publishing_ethics)., The identities of the referees will not be disclosed under any circumstances.

Journal Categories

1. Original Articles

Original articles (Research articles) should report on original primary research.

International Journal of Arrhythmia strongly encourages that all datasets on which the conclusions of the paper rely should be available to readers. We encourage authors to ensure that their datasets are either deposited in publicly available repositories (where available and appropriate) or presented in the main manuscript or additional supporting files whenever possible.

2. Review Articles

Reviews provide comprehensive and authoritative coverage of a topic.

Key aims of reviews are to provide systematic and substantial coverage of mature subjects, evaluations of progress in specified areas, and/or critical assessments of emerging technologies.

International Journal of Arrhythmia strongly encourages that all datasets on which the conclusions of the paper rely should be available to readers. We encourage authors to ensure that their datasets are either deposited in publicly available repositories (where available and appropriate) or presented in the main manuscript or additional supporting files whenever possible.

3. Commentary

Commentaries are short, narrowly focused articles of contemporary interest and usually take one of two forms:

The first form is a discussion of an article or trial that was recently published or that is soon to be published, and that is interesting enough to warrant further comment or explanation. This type of commentary discusses specific issues within a subject area rather than the whole field, explains the implications of the article and puts it in context. Opinions are welcome as long as they are factually based

The second form is more editorial in nature and covers an aspect of an issue that is relevant to the journal's scope, for example discussion of the impact of new technology on research and treatment

A maximum of ten articles may be included in the references.

4. Case Reports

International Journal of Arrhythmia welcomes well-described reports of cases that include the following:

  • Unreported or unusual side effects or adverse interactions involving medications
  • Unexpected or unusual presentations of a disease
  • New associations or variations in disease processes
  • Presentations, diagnoses and/or management of new and emerging diseases
  • An unexpected association between diseases or symptoms
  • An unexpected event in the course of observing or treating a patient
  • Findings that shed new light on the possible pathogenesis of a disease or an adverse effect.

Case reports submitted to International Journal of Arrhythmia should make a contribution to medical knowledge and must have educational value or highlight the need for a change in clinical practice or diagnostic/prognostic approaches. The journal will not consider case reports describing preventive or therapeutic interventions, as these generally require stronger evidence.

Authors are encouraged to describe how the case report is rare or unusual as well as its educational and/or scientific merits in the covering letter that accompanies the submission of the manuscript.

Preparing main manuscript text

Quick points:

  • Use double line spacing
  • Include line and page numbering
  • Use SI units: Please ensure that all special characters used are embedded in the text, otherwise they will be lost during conversion to PDF
  • Do not use page breaks in your manuscript

File formats

The following word processor file formats are acceptable for the main manuscript document:

  • Microsoft word (DOC, DOCX)
  • Rich text format (RTF)
  • TeX/LaTeX (use BioMed Central's TeX template)

Please note: editable files are required for processing in production. If your manuscript contains any non-editable files (such as PDFs) you will be required to re-submit an editable file when you submit your revised manuscript, or after editorial acceptance in case no revision is necessary.

Additional information for TeX/LaTeX users

Please use BioMed Central's TeX template and BibTeX stylefile if you use TeX format. Submit your references using either a bib or bbl file. When submitting TeX submissions, please submit both your TeX file and your bib/bbl file as manuscript files. Please also convert your TeX file into a PDF (please do not use a DIV file) and submit this PDF as a supplementary file with the name 'Reference PDF'. This PDF will be used by our production team as a reference point to check the layout of the article as the author intended.

The Editorial Manager system checks for any errors in the Tex files. If an error is present then the system PDF will display LaTex code and highlight and explain the error in a section beginning with an exclamation mark (!).

All relevant editable source files must be uploaded during the submission process. Failing to submit these source files will cause unnecessary delays in the production process.

Style and language

For editors and reviewers to accurately assess the work presented in your manuscript you need to ensure the English language is of sufficient quality to be understood. If you need help with writing in English you should consider:

  • Visiting the English language tutorial which covers the common mistakes when writing in English.
  • Asking a colleague who is a native English speaker to review your manuscript for clarity.
  • Using a professional language editing service where editors will improve the English to ensure that your meaning is clear and identify problems that require your review. Two such services are provided by our affiliates Nature Research Editing Service and American Journal Experts. BMC authors are entitled to a 10% discount on their first submission to either of these services. To claim 10% off English editing from Nature Research Editing Service, click here.
