Question:
How does mechanical strain on the right ventricular wall during rowing at low heart rates (60–70 bpm) affect the Aveir VR’s pacing threshold or local myocardial excitability, potentially leading to transient discomfort sensations?
Part 3 — Testing Protocol
- Device interrogation across HR tiers (rest, 60–70, ≥80): capture threshold, sensing, impedance.
- Exercise echo/cMRI: RV volumes & regional strain mapping synchronized to symptoms.
- 12‑lead ECG/Holter on rowing ergometer; posture/respiratory maneuvers.
- Temporary programming changes (output, pulse width, rate‑response).
