Cardio Varia TF4 - Early Heart Disease

This graph is from a person suffering from early Cardiac Autonomic Neuropathy. You can see very clearly that there is a significant difference between this graph and that of a healthy person.

The important features are that the peaks are very much reduced and also that the ratio of the heights of the peaks to each other have also changed.

As you can appreciate, the data presented in this format, is very much easier to interpret than looking closely at each individual EGC trace and measuring the R-R ratio.
