Echo (Cardiac Ultrasound)

An Echocardiogram uses ultrasound technology to study the anatomy and function of the heart including chambers, valves and blood flow. It is a safe non-invasive test that takes about 30 minutes to perform.

 

To book an Echocardiogram, have your Doctor fax this requisition to our Patient Scheduling Department and you will be called for an appointment shortly.

Sleep Lab

Our 8-bed Sleep Lab is located within the Cardiopulmonary Department. The purpose of the Sleep Lab is to perform comprehensive overnight or daytime studies to evaluate sleep disorders. It generally includes monitoring of the patient’s airflow through the nose and mouth, heartbeat as measured by an electrocardiograph (ECG), blood oxygen levels, brain wave patterns, eye movements and the movements of respiratory muscles and limbs.

The Sleep Lab can help identify such syndromes as Sleep Apnea, Narcolepsy and Insomnia.

Sleep studies require the patient to stay overnight in the Sleep Lab and appointments are made available 7 nights a week. Appointments for daytime studies are available Monday to Friday.

We accept patients 12 years of age and older.

To book a Sleep Study, have your Doctor fax this requisition to our Patient Scheduling Department and you will be called for an appointment shortly.

What to expect during your overnight Sleep Study:

Our lab is staffed with friendly, caring, qualified health care professionals including Registered Polysomnographers and Registered Respiratory Therapists.

 

  • You will be given a tour of the Sleep Lab and shown to your private room.
  • The Technologist will take a history of your sleep habits and apply small electrodes attached to thin wires onto your head via a water soluble, washable paste- this washes out easily in the morning.
  • While you sleep, the Technologist will monitor your EEG (brain waves) to determine what kind of a sleep you are having, including what  stages of sleep you enter, and whether you snore or stop breathing.
  • You are able to go to the bathroom, read if you like, toss and turn, and call the Technologist for assistance at any time during the night.
  • You will be awoken at approximately 6 am, the wires are removed quickly and you will be free to go.
  • Your Doctor will receive a summary of your sleep patterns along with a physician's report from one of our sleep specialists.

Preparation:

Night time tests:

  • No caffeine as of 12 noon on day of appointment (tea/coffee/chocolate, etc.)
  • Contact your Doctor regarding discontinuing medications prior to your sleep study.
  • Patients are asked to arrive at least 15 minutes prior to their test and have a seat in our waiting room.
  • Patients can enter through the Main Entrance doors of the hospital and follow the signs to the Cardiopulmonary Department on Level A1 beneath Tim Hortons.
  • Patients will be at their appointment until 6 am the following morning.
  • Bring in pajamas, your Health Card and CPAP headgear and mask (if applicable).
  • You are encouraged to bring your own pillow if that would be more comfortable or help you sleep better.
  •  If there are any special needs (oxygen, wheelchair, lifting), please let us know in order to make necessary arrangements.

Day time tests:   

  •  Bring something to do (ie. reading material or work). We have free wireless internet available in the department.

What is sleep apnea?  

Obstructive sleep apnea is a sleep disorder in which breathing is briefly and repeatedly interrupted during sleep. The "apnea" in sleep apnea refers to a breathing pause that lasts at least ten seconds. Obstructive sleep apnea occurs when the muscles in the back of the throat fail to keep the airway open, despite efforts to breathe.


Obstructive sleep apnea can cause fragmented sleep and low blood oxygen levels. For people with sleep apnea, the combination of disturbed sleep and oxygen starvation may lead to hypertension, heart disease, and mood or memory problems. Drowsiness due to sleep apnea can also increase the risk of a motor vehicle accident. 


What are the symptoms of sleep apnea?

  • Snoring or snorting at night.
  • Choking at night.
  • Perspiration at night.
  • Frequent night-time visits to the bathroom.
  • Morning headaches.
  • Daytime tiredness.
  • Fatigue, poor concentration, irritability.

Are there serious problems associated with sleep apnea?

  • The risk of motor vehicle accidents is 4 to 6 times greater.
  • The risk of high blood pressure and heart attacks is approximately twice as high.
  • The risk of strokes is approximately twice as high.
  • Sleep apnea may cause heart failure.

What is the treatment for sleep apnea?

Oral surgery, dental appliances, and CPAP (Continuous Positive Airway Pressure) are therapies for sleep apnea. CPAP is the most reliably effective.

EEG

An EEG (Electroencephalogram) is a test which records electrical activity of the brain. A number of electrodes are attached to the head and a recording of the signals is made. The test takes about an hour and 15 minutes.

 

To book an Electroencephalogram, have your Doctor fax this requisition to our patient scheduling department and you will be called for an appointment shortly.

EMG

An EMG (Electromyogram) is a test which records muscle activity. There are two kinds of EMG that can be performed: surface EMG and intramuscular EMG. To perform an intramuscular EMG, a very fine needle is inserted through the skin into the muscle tissue by a trained professional.

To book an Electomyogram have your Doctor fax this requisition to our Patient Scheduling Department and you will be called for an appointment shortly. 

Pulmonary Function Testing

Pulmonary Function Testing is performed to assess lung function and gas exchange. A variety of breathing maneuvers are performed with the coaching of a Respiratory Therapist. A Bronchial Provocation Test is performed to assess the sensitivity of your airways.

To book a Pulmonary Function Test or Bronchial Provocation Test have your Doctor fax this requisition to our Patient Scheduling Department and you will be called for an appointment shortly.

What to expect: 

  •   Avoid taking your inhaler for four hours prior to the test.

Cardiac Stress Test

Cardiac stress testing is performed on a treadmill and allows the monitoring of a patient’s heart rate and ECG (Electrocardiogram) while exercising. As your body works harder during the test, it requires more oxygen, so the heart must pump more blood. The test can show if the blood supply is reduced in the arteries that supply the heart. A medical professional, such as a Cardiologist Technologist, will be present throughout the test.

What to expect:

  • Be prepared to spend approximately 30 minutes at the hospital.
  • A Cardiac Technologist will take you to your room and answer any questions you may have regarding your Cardiac Stress Test.
  • You will be hooked up to equipment to monitor your heart and blood pressure.
  • You will start by walking slowly on a treadmill, then the speed of the treadmill will be increased and the treadmill will be tilted to produce the effect of walking up a small hill.
  • The Cardiac Stress Test can be stopped at any given time, if needed.
  • After coming off the treadmill, you will be asked to sit or lie down to have your heart and blood pressure checked.

Preparation for your test:

  • Please bring a list of all current medications as well as comfortable clothes and shoes for exercise.
  • You may take all of your current medications as you normally would unless your Physician has instructed you to stop them prior to your test consult your Doctor regarding discontinuation prior to the test
  • Do not smoke, eat or have any caffeine for 2 hours prior to your test

To book a Cardiac Stress Test have your Doctor fax this requisition to our Patient Scheduling Department and you will be called for an appointment shortly.

Holter Monitoring

A Holter Monitor records 24 to 48 hours worth of Electrocardiogram (ECG) information and is used to identify heart rate abnormalities. We also offer a 14-day event-recording monitor (Loop Recorder) that can provide similar information. The device is the size of a pager and is equipped with a number of electrodes and wires that get attached to your skin to record the information.

To book a 24- or 48-hour Holter Monitor or a 14-day Loop Recorder have your Doctor fax this requisition to our Patient Scheduling Department and you will be called for an appointment shortly.

Electrocardiogram (ECG)

An Electrocardiogram (ECG) is a 12-lead view of the electrical activity of the heart. A number of stickers are placed onto your chest and limbs and a quick recording is made.

To book an ECG have your Doctor fax this requisition to our patient scheduling department and you will be called for an appointment shortly.
