We offer treadmill testing, as well as Lexiscan for those who cannot participate in treadmill testing. Your provider will help you decide on the best course of action for your testing. Please check back for the dates we host our cardiac testing events and let your provider know which date will work best for you.

Information About Your Stress Test (click to expand)


Your stress test study will take between 2.75 and 4 hours. Feel free to bring a book, a music player, etc. Please anticipate needing to return completed forms or to fill out your forms prior to your test beginning.

Your stress test will begin by inserting an IV line into your arm to allow injection of an isotope and medications (if needed) into your veins as part of your study. Your heart will then be imaged while you are at rest.

Your technician will then attach electrodes to your chest much like when you’ve had EKG’s done in the past. These electrodes will be connected to an EKG machine which will be used to monitor your heart rate and rhythm. You will be asked to walk and jog on a treadmill until your heart rate reaches 85% of your maximum predicted heart rate (Based on your age, weight, and other factors). Once your heart rate has increased adequately, more of the isotope will be injected for additional pictures to be taken.

Preparation for Your Stress Test (click to expand)


1. Do not smoke, drink regular or decaffeinated coffee, tea, sodas, or any other caffeinated beverages for 24 hours prior to your procedure. Do not each chocolate either, as it contains caffeine as well.
2. Do not eat or drink anything at least 6 hours before your procedure, except water. Please drink plenty of water if you have hard-to-detect veins.
3. Bring a light snack (peanut butter crackers, sandwich, beverages, or other options). During your procedure, you may be asked to eat to encourage a different or even better picture of your heart. Please bring water with you, as you will need to drink during the use of isotopes.
4. If you are diabetic, please speak with your physician regarding special dietary instructions, if any.
5. Please shower or bathe the day of the test. Please DO NOT apply body lotion or powder to your chest.
6. Wear loose fitting slacks or shorts, a shirt or blouse with buttons on the front, and tennis shoes or walking shoes. NO METAL UNDERWIRE BRAS.
7. Your physician may ask you to discontinue certain medications for 24-48 hours prior to your study.
8. Do not take any erectile dysfunction medication within 72 hours of the test (including Viagra, Cialis, Levitra, etc).



Cardiac Event Testing


CMG offers 24 hour Holter monitor and Cardiac Event Monitor Testing. Your primary care provider will discuss these tests with you and whether or not you will need to wear a monitor.

Echocardiograms and Ultrasounds


CMG performs echocardiograms (sometimes known as Echos) and ultrasounds on 3 days a month. We offer these services on the 1st, 2nd, and 4th Tuesday of every month. Your care provider will assist you in scheduling your testing accordingly.

Bone Density Scanning


Our office offers Dual-Energy X-Ray Absorptiometry (DEXA) scans to screen for osteoporosis and other bone density issues. We perform DEXAs Monday through Friday from 8:30 am until 5:00 pm using our state-of-the-art Hologic scanning system.
We also perform body composition screenings, to assist in weight management.

Therapeutic Phlebotomy


CMG performs this procedure for patients with Hemochromatosis and Polycythemia. We will draw out 500ml’s of blood in order to assist you. This is the same amount that a person would typically give during a Red Cross blood drive.

IV Therapy


Dehydration can occur in anyone- especially during flu season. Our IV therapy replaces the essential fluids that the body requires to function. Your care provider will decide if this is the proper course of action to take in order to assist you.
