The non-invasive echocardiography laboratory at Baylor Scott & White The Heart Hospital – Dallas offers a comprehensive range of basic to advanced non-invasive cardiac procedures and technologies to diagnose heart disease. Backed by over 20 years of combined, specialized experience in the field, we pride ourselves on delivering safe, quality care in a patient-centered environment here in Dallas.
The non-invasive cardiology department at our Dallas heart and vascular hospital is staffed with nationally registered sonographers who work closely with cardiologists on the hospital’s medical staff to quickly and accurately diagnose your heart condition. This team focuses on achieving the best outcomes for patients by using safe and virtually painless methods—including no radiation exposure and less risk than invasive procedures—allowing patients to resume normal activities almost immediately after the non-invasive cardiology procedure.
The non-invasive vascular lab at our Dallas heart center is accredited by the Intersocietal Accreditation Commission (IAC) in peripheral venous, peripheral arterial and extracranial cerebrovascular duplex (carotid Doppler) examinations. The non-invasive department has been accredited in vascular testing since 2005 with specially trained and nationally registered sonographers. The physicians on the medical staff include board-certified vascular surgeons, cardiologists and other specialists.
A doctor at our Dallas heart and vascular hospital holds a medical device while talking with a patient connected to electrodes. Electrodes (small, plastic patches that stick to the skin) are placed at certain locations on the chest, arms and legs. When the electrodes are connected to an ECG machine by wires, the electrical activity of the heart is measured, interpreted and printed out. No electricity is sent into the body, and there is nothing painful or uncomfortable involved in an ECG.
Natural electrical impulses coordinate contractions of the different parts of the heart to keep blood flowing in the right directions, and in the proper amounts. An ECG records these impulses to show how fast the heart is beating, the rhythm of the heartbeats and the strength and timing of the electrical impulses. Changes in an ECG can be a sign of many heart-related conditions.
An electrocardiogram may be done on an outpatient basis or as part of your hospital stay. In a private examination room, the technician will ask you to lie on a bed or table. Certain areas of your arms, legs and chest will be cleaned and, in some instances, shaved. This provides a clean, smooth surface for attaching the electrodes.
Several electrodes are attached to the skin on each arm and leg and on your chest, sometimes along with a dab of electrode paste to aid in electrical conductivity. The electrodes, then, are hooked to the ECG machine. During the test, you will be asked to lie very still and breathe normally. Sometimes you may be asked to hold your breath. You should not talk during the test.
Once the test is completed—usually after only five or 10 minutes—the electrodes are carefully removed, and any electrode paste is wiped off.
