MARKET CATALYSTS

GROWING ACCESS GAP

20 years advancing cardiac diagnostics and innovating to detect, predict, & prevent disease.

*See appendix for sources

Heart rhythm problems are among the most prevalent conditions in the Medicare population aged 65 and over.*

Aging population, consumer arrhythmia awareness, proliferation of therapies like pulsed field ablation, recognition of post-ablation monitoring, trends toward proactive medicine, and a growing shift to value-based care driving TAM growth.

46.3% of all U.S. counties -

and 86.2% of rural counties

- lack cardiologists and non-urgent cardiology wait times average 26.6 days & rising.*
