Mitochondrial respiratory control ratios (RCR) taken from different regions of a heart from a patient with hypertrophic cardiomyopathy. RCR defined as state 3/state 4 represents a strong indicator of an intact coupled oxidative phosphorylation. Note lower numbers for all substrates from the septum isolates.

Mitochondrial respiratory control ratio (RCR) by site for the different substrates*
Site	RCR for Palmitoyl Carnitine	RCR for Pyruvate Malate	RCR for Glutamate Malate	RCR for Succinate
LV apex	5.0616	3.0713	7.1832	1.5599
RV free wall	3.9818	3.4478	7.6043	1.5005
LV Septum	3.0000	2.1090	2.5667	1.0000
