Available Tests:

  • Echocardiography
    a test of the action of the heart using ultrasound waves to produce a visual display, for the diagnosis or monitoring of heart disease

  • ECG (Electrocardiography)
    the measurement of electrical activity in the heart and its recording as a visual trace (on paper or on an oscilloscope screen), using electrodes placed on the skin of the limbs and chest

  • Stress Testing
    a test of cardiovascular fitness made by monitoring the heart rate during a period of increasingly strenuous exercise (e.g. on a treadmill)

  • Holter Monitoring
    a small device (Holter Monitor) will be strapped to you. Wires from the device will be attached to electrodes (usually five) affixed to your chest. You will be instructed to keep a diary of your activities for the next 24 hours, and then return the device and your diary for analysis

  • Pulse Oximetry
    a device measures the amount of saturated haemoglobin in the tissue capillaries by transmitting a beam of light through the tissue to a receiver. This noninvasive method of measuring the saturated hemoglobin is a useful screening tool for determining basic respiratory function. This cliplike device may be used on either the earlobe or the fingertip. As the amount of saturated hemoglobin alters the wavelengths of the transmitted light, analysis of the received light is translated into a percentage of oxygen saturation (SO2) of the blood. Also called (informally) pulse ox. Compares blood gas determination.
  • 24-Hour Blood Pressure Monitoring  (ABPM)
    Ambulatory Blood Pressure Monitoring (ABPM) is when your blood pressure is being measured as you move around, living your normal daily life. It is normally carried over 24 hours. It uses a small digital blood pressure machine that is attached to a belt around your body and which is connected to a cuff around your upper arm.
