Holter monitoring

This is a test used to diagnose cardiac arrhythmias which may be accounting for the patient’s symptoms, such as fainting or palpitations.  The patient carries a Holter box connected to electrodes on the chest usually for 24 hours, and sometimes up to 48 hours.  This is a noninvasive test.

Event recorders

Similar to a Holter monitor, event recorders usually involve wearing the recording machine for a longer duration of up to 30 days.  It is usually used to monitor heart rhythm disorders that occur in a sporadic fashion.

Carotid Doppler

This is an imaging technique which uses ultrasound waves to detect blockages and the degree of thickness of the intima of the carotid arteries (arteries which supply the brain and are present in the neck).

Lower/upper extremity arterial Doppler and venous Doppler

In this test, arteries and veins of the upper and lower extremities are visualized for obstruction and clots by ultrasound waves.

ABI (ankle brachial index)

This is a test to check for obstruction of leg arteries by comparison of blood pressure recordings between the upper and lower extremities.

Abdominal Aortic Aneurysm Detection

Ultrasound waves are used to detect the size of the abdominal aorta. The test is usually recommended for male smokers 65-years or older or for patients with a family history of clinical symptoms that need this test.

Renal Duplex Scan

Ultrasound waves are used to detect any significant narrowing of renal arteries. The test is usually recommended for patients in whom blood pressure is difficult to control and also if there is a clinical suspicion of renal artery narrowing.

INR/Coumadin clinic

Finger stick blood is used to check adequacy of blood thinning by Coumadin (warfarin).
