  • Good morning all,
    I am a new owner/user of the Frontier X and as a data nut, I am very enthused about it so far.
    I’m a 78 year old male with frequent PVC’s that do not seem to cause any issues.
    I’ve had 4 Stress tests since 2012 and all after the first have been clean.
    My Cardioligist has offered bata blockers but I have declined.

    • Hello, I’m a retired cardiovascular safety pharmacologist. You are not wrong in your thinking, but exactly correct. The upper trace is, as you note, at a cycle length of ~ 1 sec (970 ms to be exact). The associated QT for the first and second beats on the upper trace are 433 ms each, exactly as you measured. You shouldn’t include beats associated…Read More

  • The cardiac strain indicates blood supply to the heart. Does this correlate with possible blood pooling.
