Aim: To analyze the agreement of the Firstbeat real-time heart rate monitor in comparison to an ECG in women. Methods: 7 physically active women were recruited to realize two recordings of RR intervals on two days separated by 7 days. The recordings were conducted with the volunteers seated on the Leg Press 45 apparatus. For the recording of the RR intervals, a three-lead electrocardiogram (ECG) recording, coupled to the Finometer, and the Firstbeat real-time monitor were used. Statistical analysis was performed using SPSS software (26.0). Results: There was no significant difference on both days (p > 0.05) in the paired T-test. On day 1, a perfect correlation was found in the Pearson correlation test (r = 1.0), and on day 2, a very strong correlation was observed (r = 0.99). Additionally, no proportional bias was identified in the Bland-Altman test. The mean of the RR intervals was consistent between the Finometer ECG and the Firstbeat monitor in women.
