Accuracy and clinical utility of heart rate variability derived from a wearable heart rate monitor in patients undergoing major abdominal surgery
Authors' conclusion
The substantial agreement between Polar H10 and Holter ECG may justify its use clinically.
Study context
- Population
- Patients undergoing major abdominal surgery with GA
- Participants
- 23 patients
- Comparison
- Polar H10 HR monitor vs Holter electrocardiograph (ECG); Total power (TP) < 500 vs > 500 ms2 for predicting intraoperative hypotension
- Outcome
- Level of agreement between Polar H10 and Holter ECG

Performance
As reported in the abstract
Agreement between Polar H10 and Holter ECG
- Substantial agreement between Polar H10 and Holter ECG for average R-R interval, TP and other heart rate variability (HRV) indices
Further findings
| Outcome | Values |
|---|---|
| Prediction of intraoperative hypotension by reduced TP (< 500 ms 2 ) | Reduced TP sensitivity 80% · specificity 100% |
- Prediction of intraoperative hypotension by reduced TP (< 500 ms 2 ): intraoperative hypotension: MAP < 60 mmHg, SBP < 80 mmHg, or 35% decrease in MAP from baseline
Need for vasoactive drugs to maintain BP
- Patients with reduced TP significantly more likely to require vasoactive drugs
