Stresses are performed when desired information cannot be obtained from a standard stress ECG alone . IV Thalium Stress ECGs are stress ECGs in which stress is chemically induced rather than exercise induced. These stress test are performed when patients are unable to exercise and in instances where adequately increase heart rates are unobtainable. The tape is then returned to our lab for scanning and interpretation by a cardiologist. Our service is provided to patients in our immediate area as well as outreach sites throughout North Dakota and parts of South Dakota.
Event Recorders are patient activated devices used to record the electrical activity of the heart.
The recording is transmitted over the telephone to a receiving center at the Heart and Lung Clinic and analyzed by a cardiologist. In addition to cardiac testing, the Noninvasive Cardiovascular lab also performs diagnostic vascular testing including carotid duplex and venous duplex ultrasonography. Carotid Duplex Ultrasonography utilizes two dimensional imaging and doppler to determine the degree of stenosis of the carotid arteries. The subclavian and vertebral arteries are also assessed for flow abnormalities. Venous Duplex Ultrasonography utilizes two dimensional imaging and doppler to assess the deep veins of the extremities for venous occlusive disease.
