CardioSD Procedures

Office Procedure Details

ABI (Ankle/Brachial Indices):  Using the ultrasound probe, the blood pressures at the arm (brachial area) and at the ankle are checked. They are looking for differences that give the physicians information in diagnosing peripheral arterial disease.

Adenosine Nuclear Stress Testing:  The patient is injected with a drug (Adenosine) for 4 minutes while the patient either is walking or moving their legs. The patient’s heart is continuously monitored. The heart rate is not increased, but the heart’s blood vessels are dilated so the reaction can be monitored.

Dobutamine Stress Echocardiogram:  This test is done for patients who cannot walk on a treadmill . For this test, the patient will remain seated for the whole procedure. A medicine, Dobutamine, is injected via an IV into the patient’s vein. This medicine will speed up the patient’s heart rate similar to the response that would be expected had the patient walked on the treadmill.

Echocardiogram:  A non-invasive procedure where the sonographer places a transducer on the patients heart while the patient is in a resting position. The transducer uses high frequency sound waves to visualize the heart chambers, the thickness of the muscle wall, the heart valves and the major blood vessels around the heart.

Electrocardiogram (EKG):  The patient is connected by electrodes to an EKG machine. A graph or tracing of the electrical conduction system of the heart is printed for the physician’s review.

Holter/Event Monitoring:  The patient is connected to a small recorder by electrodes from the chest. Length of times can vary from 24hrs, 48 hrs, or even up to 30 days (Event Monitor). The patient is asked to keep a diary of symptoms and activities so that heart rates and responses can be evaluated with daily activities.

Nuclear Stress Testing :  Before the treadmill portion of the stress test, the patient is injected, via an IV in the arm or hand, with a radioactive substance called Cardiolite. This isotope is about the equivalent to a chest x-ray in terms of radiation. Pictures of the heart will be taken before the stress part of the study and then afterwards. This gives the physician information of the blood flow to the heart, both at rest and after exercise.

PTT / INR:  Patients that have been prescribed to take a blood thinner such as Coumadin, ( Warfarin) will be required to have their blood tested frequently to allow for proper dosage adjustment.

Regular Stress Testing:  The patient will walk on a treadmill and be connected by electrodes placed on their chest that will trace their heart rhythm. They are asked to walk as long as possible. The treadmill increases in speed and incline at certain intervals to create more resistance for the patient, thus putting more work load on the heart.

Stress Echocardiogram:  This is done in conjunction with a regular treadmill stress test. During and after walking on the treadmill the echo technician will record images using a transducer on the outside of the chest to detects how the heart is contracting, how the valves are working, and measures the size of the heart chambers.
