The Non-Invasive Cardiovascular Laboratory (NCL) is equipped with the most up-to-date diagnostic equipments including sophisticated echocardiography machines for performing two and three dimensional echocardiograms, conventional and tissue Doppler echocardiograms, colour flow mapping of these echocardiograms and for obtaining and recording echocardiograms during stress testing, dobutamine infusion and contrast infusion.
The NCL is an outpatient and inpatient facility that performs cardiovascular and peripheral vascular diagnostic procedures on patients known or expected of having cardiac and vascular disorders. Patients have access to a full range of non-invasive diagnostic tests performed and evaluated by an experienced team of cardiologists and specialized technicians and nurses. The team with its support staff are involved in new and ongoing research focused on equipment development, device and drug interventions. The Non-Invasive Cardiovascular Laboratory has two sections –
- Electrocardiography – This section performs electrocardiograms, tilt table studies, holter monitoring, event monitoring, ambulatory blood pressure monitoring, pacemaker follow-up clinic, implantable cardiac defibrillator follow-up clinic tilt table studies and cardioversions.
- Echocardiography – This section performs echocardiograms including transesophageal echocardiograms, exercise stress echocardiograms, 2D/Doppler and pacing cardiograms.
Treatments and Studies
The department gives out an exclusive range of non-invasive cardiology studies, including –
- Tilt Table Test : If patient suffers from frequent fainting spells, the cardiologist may order a tilt-table test. During the test blood pressure and heart rate is monitored as the patient lie flat on a table. Then the table is tilted upward so that the patient comes in standing position and as the position changes, the changes in heart rate and blood pressure show whether it is a heart rhythm problem which is causing you faint.
- Electrocardiogram (EKG/ECG) : This is a painless test that uses electrodes placed on the skin to record the heart’s electrical activity. The test provides information about the heart rhythm and damage to the heart muscle.
- Stress test : A cardiac test is done when the patient is at rest but his heart is stressed or working hard. The test can show how the heart responds to increased workload. This test may involve walking on a treadmill or medications to increase the heart rate.
- Pharmacological (Drug-Induced) Stress test : This test is done on patients who are unable to walk on treadmill. In this case, only medication is provided which stresses the heart for further treatment procedure.
- Nuclear Stress Testing : In this test, radionuclide material is used to measure the functioning of heart while walking on treadmill. In addition to measuring heart’s electrical activity during stress, a nuclear study provides pictures of the heart.
