Metabolic Rate at Rest and Exercise

Metabolic rate is the rate at which your body uses energy to perform all the different types of work necessary for maintenance, growth, repair, etc. So, your M.R. is the sum of all energy-requiring processes in all the cells of your body--ALL CELLS, not just muscle cells. It varies depending upon physiological state

12 Lead ECG

The 12-lead ECG gives a tracing from 12 different “electrical positions” of the heart.  Each lead is meant to pick up electrical activity from a different position on the heart muscle.  This allows an experienced interpreter to see the heart from many different angles


Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs), measuring lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is an important tool used for generating pneumotachographs, which are helpful in assessing conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and COPD.
