, Good luck with the upcoming appointment, I sometimes write my questions down beforehand to make sure that I do not forget and get derailed in the appointment. LV , would refer to the Left Ventricle. I do believe the LV mass is the weight of the Left ventricle. I would certainly suggest that you ask your doctor in your upcoming appointment to explain what the normal range is for you.
Do you feel ready for the next appointment?
Warmly,
