Heart Rhythm O2

Our screening does not flag Heart Rhythm O2. That is not a guarantee of quality — it means the venue is not on Beall's archive (frozen since 2017) and does not match our name-pattern heuristic. It is listed in DOAJ, Scopus, Web of Science, PubMed, which is a positive signal.

Per our venue index, Heart Rhythm O2 appears in: DOAJ, Scopus, Web of Science, PubMed. Index membership changes over time — confirm on the index's own site before relying on it.

Papers in Heart Rhythm O2 are cited about 1.3 times each within two years of publication, and Scimago places it in Q2, with an h-index of 30. This is not a Clarivate Journal Impact Factor — we neither compute nor license that metric — and a citation rate is a property of a field as much as of a journal.

Our index records its access status as "gold". Where this is derived from publisher-level signals rather than works-level data it is a heuristic, so confirm on the journal's own site — particularly if an article processing charge matters to you.
