The estimated HR results of the different methods (M1–3) and ECG ground truth HR regarding the clinical trial
| (CT-A) selected measurement | #1 | #2 | #3 | #4 | #5 | #6 | #7 | #8 | #9 | #10 |
|---|---|---|---|---|---|---|---|---|---|---|
| Peak detection (HR) (bpm) (M1) | 94 | 86 | 110 | 77 | 89 | 96 | 112 | 95 | 88 | 94 |
| Deviation from ECG (in bpm) | 28 | 0 | 47 | 3 | 20 | 2 | 5 | 8 | 4 | 44 |
| Single-axis autocorrelation HR (bpm) (M2) | 67 | 79 | 64 | 80 | 69 | 93 | 110 | 86 | 82 | 115 |
| Deviation from ECG (in bpm) | 1 | 7 | 1 | 0 | 0 | 5 | 7 | 1 | 2 | 23 |
| 6-axis autocorrelation HR (in bpm) (M3) | 68 | 69 | 64 | 71 | 68 | 60 | 83 | 85 | 78 | 81 |
| Deviation from ECG (in bpm) | 2 | 17 | 1 | 9 | 1 | 38 | 34 | 2 | 6 | 57 |
| ECG ground truth HR (bpm) | 66 | 86 | 63 | 80 | 69 | 98 | 117 | 87 | 84 | 138 |
It can be observed that method M2 gives the lowest mean deviation from ECG. Measurements 1–2 and 4–9 are from Dobermans, while 1–2 are in a right lateral and 4–9 in a standing position. The measurements 1 and 5 are from the same dog. Measurements 3 and 10 are from Whippet and Newfoundland dog, respectively (both in a standing position)
