Do not agree on cardiac work

its says "PV loops fail to account for the heart rate (which has an effect on myocardial oxygen consumption, which in turn is proportional to cardiac work)"

While true that a higher heart rate means the cell consumes more oxygen, the cells do not consume more because they do more work per stroke, they simply do more strokes per unit time. So heart rate is not related to cardiac work, its related to cardiac power output(work per unit time). Hence this line should be omitted as a factor for the inaccuracy of pv-loop area as an estimate for work.217.122.183.107 (talk) 21:43, 4 October 2011 (UTC)[reply]

PV Plane

The term PV plane is mentioned 4 times in the article with no reference to what it is or means. I would fix this but I don't know what "PV Plane" refers to. — Preceding unsigned comment added by Psutty (talk • contribs) 14:15, 10 April 2015 (UTC)[reply]
