Key result
Handheld single-lead ECG achieves 94% concordance with 12-lead ECG for detecting rhythm abnormalities suggesting PPCM.
Why the study?
Peripartum cardiomyopathy is a major cause of maternal morbidity and mortality in Nigeria, but early detection is challenging because conventional 12-lead ECGs are often unavailable in primary and secondary care facilities.
Does a handheld single-lead ECG device demonstrate comparable diagnostic efficacy to a standard 12-lead ECG for peripartum cardiomyopathy screening in pregnant and postpartum women?
Cross-Sectional (n=850)
Yes
Does a handheld single-lead ECG device demonstrate comparable diagnostic efficacy to a standard 12-lead ECG for peripartum cardiomyopathy screening in pregnant and postpartum women?

A handheld single-lead ECG device provides high diagnostic concordance (94%) with standard 12-lead ECGs for detecting PPCM-related rhythm abnormalities and is highly feasible for routine antenatal screening in resource-constrained settings.
Peripartum cardiomyopathy (PPCM) is a significant cause of maternal morbidity and mortality in Nigeria. Early detection is challenging, particularly in resource-constrained settings where conventional 12-lead electrocardiogram (ECG) machines are often unavailable in primary and secondary care facilities. This study compared the adoption, feasibility, and clinical efficacy of a handheld single-lead ECG device with a standard 12-lead ECG for PPCM screening in a Nigerian antenatal population. A comparative study was conducted from January to December 2021 at two tertiary hospitals in Enugu, Nigeria. We enrolled 850 women in their third trimester or immediate postpartum period. Each participant underwent concurrent cardiac rhythm assessment with both the handheld device and a conventional 12-lead ECG. Structured questionnaires collected clinician feedback on device adoption. The handheld ECG demonstrated 94% concordance with the 12-lead ECG for detecting major rhythm abnormalities suggestive of PPCM. Regarding adoption, 78% of clinicians reported the handheld device was easier to integrate into routine antenatal checks. The primary barrier was initial cost, cited by 65% of respondents. Handheld ECG devices showed high diagnostic concordance with standard ECGs for key PPCM indicators and were perceived as more feasible for routine screening by most clinicians in this setting. Health policy makers should consider pilot programmes for deploying handheld ECG devices in antenatal clinics, accompanied by targeted training. Further cost-benefit analyses are required to address cost-related adoption barriers. peripartum cardiomyopathy, handheld electrocardiogram, maternal health, screening, Nigeria, antenatal care This study provides comparative data on the practical adoption and diagnostic performance of a portable ECG device for PPCM screening in a resource-constrained setting.

Adeyemi et al. (2021) conducted a cross-sectional in Peripartum cardiomyopathy (n=850). Handheld single-lead ECG device vs. Standard 12-lead ECG was evaluated on Concordance for detecting major rhythm abnormalities suggestive of PPCM. A handheld single-lead ECG device demonstrated 94% diagnostic concordance with a standard 12-lead ECG for detecting major rhythm abnormalities suggestive of peripartum cardiomyopathy.
