After literature review, meta- & network meta-analyses, evidence inadequate to draw reliable conclusions about antihypertensive impacts on FHR or neoHR. Adverse FHR effects should be attributed to evolving placental dysfunction & neoHR effects to illness obgyn.onlinelibrary.wiley.com/doi/10.1111/...
