Manuscript Overview


JAFIB-EP publishes original articles related to the diagnosis, management and research of cardiac rhythm disorders and other associated conditions. The content of JAFIB-EP is determined by the Editors.

JAFIB-EP, the Publisher, and the Editors of its publications assume no responsibility for the statements expressed by the contributors (and/or authors) of the articles.

The manuscript which is submitted to the journal must not contain previously published material or material under consideration for publication elsewhere. Accepted manuscripts become the property of JAFIB-EP and may not be republished. Use of published manuscripts must be approved by JAFIB-EP editorial team.

All manuscripts will undergo editorial review. A final review and a subsequent decision about publication will be made by the JAFIB-EP editor.


Author Responsibilities

Each author listed on the publication for publication in JAFIB-EP acknowledges that they have made a substantial contribution to the publication by the following:

1 – The conception and design of the study

2 – The analysis and interpretation of the results

3 – The writing of the paper

4 – The author has approved the final submitted version of the publication

Each author thus also acknowledges responsibility for the integrity of the manuscript, assures the originality of the manuscript, and guarantees that duplicate or redundant publications or submissions have not occurred. The editors reserve the right to request the original data obtained in the publication. Authors are responsible for all statements made in the text.


Manuscript Submission

  • The authors should submit the manuscript as a complete file.
  • Submit an electronic version of text (as a MS WORD document), unlabeled and labeled images (as JPEG files).
  • The manuscript should be typed in Times New Roman font, double-spaced throughout on one side of A4/Letter paper with at least a 2.5 cm/1 inch margin on all sides. Number all pages consecutively, beginning with the title page.
  • There are no restrictions to page counts or number of figures/videos, however in the interest of readers we suggest limiting to a 10-12 page maximum.
  • Prepare a cover letter and the author license form (has to be sent via post or fax) signed by all authors. You can 
  • Organize the manuscript as follows: title page, abstract, introduction, material and methods, results, discussion, conclusion, acknowledgments, references, figure legends, and tables.
  • Keep acronyms and abbreviations to a minimum. When an abbreviation is used, define it at first mention and follow with the abbreviation in parentheses.
  • Style and Punctuation of References

These instructions are based in part on recommendations in the Uniform Requirements for Manuscripts Submitted to Biomedical Journal [Ann. Intern. Med. 1997; 126: 36-47]. Variations from guidelines in this publication reflect the individual style of JAFIB-EP.
