Cardio-Respiratory Investigation information

ECGElectrocardiography (ECG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on a patient’s body. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle depolarizing during each heartbeat.

Exercise Tolerance TestAn exercise ECG is an electrocardiogram (ECG) that is recorded while you are walking on a treadmill or cycling on an exercise bike. The aim of the test is to see how your heart works when you are more active. The exercise ECG helps doctors find out if you have coronary heart disease, as it shows whether your heart muscle is getting enough blood from the coronary arteries during physical activity. An exercise ECG is also helpful for looking at how well your heart is working after heart surgeries and procedures, such as coronary bypass surgery or coronary angioplasty.

24 Hour & 7 Day Holtor monitor A 24hr / 7 day Holter monitor is a battery-operated portable device that measures and digitally records your heart’s activity (ECG) continuously for 24 to 48 hours or longer depending on the monitor used. The device is the size of a small camera. It has wires with electrodes that attach to your skin.

Cardio Memo FittingIf you have symptoms that don’t happen frequently, your doctor might suggest using a cardiac event recorder. This can record the heart’s activity for a longer period of time, or whenever symptoms occur, in a similar manner to a Holtor monitor.

Spirometry Breathing TestSpirometry is used to measure a persons lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is an important tool used for generating pneumotachographs, which are helpful in assessing conditions such as asthma, pulmonary fibrosis, cystic fibrosis and COPD.

Pulmonary Function TestPulmonary function tests are a group of tests that measure how well your lungs work. This includes how well you are able to breathe and how well your lungs are able to supply oxygen to the rest of your body. Pulmonary function tests can be used to help diagnose asthma, allergies, chronic bronchitis, respiratory infections, emphysema, lung fibrosis, bronchiectasis, chronic obstructive pulmonary disease (COPD), asbestosis, scleroderma, pulmonary tumor, lung cancer and sarcoidosis inflammation in the lungs, liver, lymph nodes, eyes, skin, or other tissues.

Pacemaker / ICD follow checkPatient pacemaker follow up checks are performed on patients post having a pacemaker implanted; the device and wellbeing of the patient are monitored and investigated on a routine basis. Interrogation of the device is performed to preserve battery longevity and to optimise the pacemaker function to best suit the patients needs.

EchocardiogramAn echocardiogram (also called an echo) is a type of ultrasound test that uses high-pitched sound waves that are sent through a device called a transducer. The device picks up echoes of the sound waves as they bounce off the different parts of your heart. These echoes are turned into moving pictures of your heart that can be seen on a video screen.

The different types of echocardiograms are:

  • Transthoracic echocardiogram (TTE). This is the most common type. Views of the heart are obtained by moving the transducer to different locations on your chest or abdominal wall.
  • Stress echocardiogram. During this test, an echocardiogram is done both before and after your heart is stressed either by having you exercise or by injecting a medicine that makes your heart beat harder and faster. A stress echocardiogram is usually done to find out if you might have decreased blood flow to your heart (coronary artery disease).
  • Doppler echocardiogram. This test is used to look at how blood flows through the heart chambers, heart valves, and blood vessels. The movement of the blood reflects sound waves to a transducer. The ultrasound computer then measures the direction and speed of the blood flowing through your heart and blood vessels. Doppler measurements may be displayed in black and white or in color.
  • Transesophageal echocardiogram (TEE). For this test, the probe is passed down the esophagus instead of being moved over the outside of the chest wall. TEE shows clearer pictures of your heart, because the probe is located closer to the heart and because the lungs and bones of the chest wall do not block the sound waves produced by the probe
