Standard guidelines recommend at least ≥20/7 daytime/nighttime measurements for reliable ambulatory BP monitoring, but newer reports suggest ≥8/4 daytime/nighttime measurements are sufficient. Considering BP oscillates across the night, the temporal distribution of measurements across the night may impact nighttime BP and dipping%. To test whether this new recommendation holds for extreme examples of temporal distribution, we compared average nighttime BP and dipping% when using BP measurements only in the first (1st-half) vs. only in the second half (2nd-half) of the night.}, number = {IR}, doi = {https://doi.org/10.6083/bpxhc41336}, recid = {41336}, address = {2023-07-24}, }
