Heart failure & cardiomyopathies
Feasibility of Physiological Pacing Rate in Cardiac Resynchronization Therapy
Authors' conclusion
In mildly symptomatic CRT patients PPR is feasible, leading to improvements in functional capacity.
Study context
- Population
- Clinically mildly symptomatic cardiac resynchronization therapy (CRT) patients
- Participants
- 30 patients
- Comparison
- CRT with physiological pacing rate vs CRT at nominal settings
- Outcome
- Maximum walking distance during 6MWT
Methodological detailsmatched control group, blinded for patients and 6MWT evaluator, pre to post
- Matched control group
- Blinded for patients and 6MWT evaluator
- Pre to post
Main finding
As reported in the abstract
Maximum walking distance (6MWT)
P = 0.001
Further findings
Variation in walking distance vs baseline trials
P = 0.007
| Outcome | Increase (m) | P value |
|---|---|---|
| Increase in walking distance vs baseline trial9.2% | 40.5 | P < 0.0001 |
