EKG - tracing electrical activity in the heart. Clinical indications include chest pain, shortness of breath, pre-op evaluation, post-op evaluation, heart attack or palpitations.

Signal Average EKG - more extensive tracing of the electrical activity in the heart. Clinical indications include heart attack, unexplained syncope, ventricular arrhythmias and screen for electrophysiology study.

Holter Monitor - 24 hours of continuous EKG captured on a digital disk while client is in normal daily activity. Clinical indications include undocumented arrhythmias, unexplained symptoms such as weakness, dizziness, syncope and palpitations.

Routine Cardiac Stress Test - EKG recording performed before, during and after exercise on the treadmill. Clinical indications include chest pain in a patient with a normal EKG, screening tool for patients with normal EKGs, evaluation of fitness in patients post heart attack or post-op.

Nuclear Cardiac Stress Test - EKG tracings recorded in conjunction with nuclear images of the heart at rest and again during stress. Clinical indications include chest pain in a patient with an abnormal EKG, noninvasive evaluations of myocardial perfusion. These are often called a sestimibi or thallium stress test.

Segmental pressures - arterial blood pressures of segments of the extremities are taken along with arterial Doppler evaluation at multiple sites along the extremity. This test also may be called a PVR or arterial Doppler study. Clinical indications include an evaluation of arterial blood flow.

Arterial Imaging - imaging of the arterial system of an extremity using ultrasound. Clinical indications include evaluation of arterial blood flow, especially in patients with arteriosclerosis that prevents compression of the vessels with blood pressure cuffs.

Venous imaging - imaging of the venous system of an extremity using ultrasound. May also be called a venous Doppler study. Clinical indications include suspicion of deep venous thrombosis or evaluation of venous valve competency.

Carotid dopscan - imaging of the extracranial carotid arteries using ultrasound. Clinical indications include symptoms of a stroke, amaurosis fugax, syncope, dizziness, carotid bruit, unequal bilateral brachial blood pressures or pre-op evaluation.

Echocardiogram - ultrasound imaging of the heart from the transthoracic location. Also called a cardiac sonogram or TTE. Clinical indications include all cardiac diagnosis (CHF, heart attack, murmur, chest pain, etc.)

Transesophageal Echocardiogram - Ultrasound imaging of the heart with a transducer mounted on the end of a flexible probe inserted into the esophagus. Clinical indications include a need for a clearer picture.

Leg and Arm Studies:
A. Segmental Pressures – arterial blood pressures of segments of the upper and lower extremities are taken along with arterial Doppler evaluation at multiple sites along the extremity. This test also may be called a PVR or arterial Doppler study. Clinical indications include claudication (pain that occurs with exercise) or suspicion of inadequate blood supply to the limbs.

B. Arterial Imaging – imaging of the arterial system of an extremity using ultrasound. Clinical indications include suspicion of plaque in the arteries, possibly resulting in decreased blood flow to the limbs or possible complications of an invasive procedure such as angiography.

C. Venous Imaging – imaging of the venous system of an extremity using ultrasound. May also be called a venous Doppler study. Clinical indications include suspicion of deep venous thrombosis or evaluation of venous valve competency.
