How long does an Echocardiogram take?

An echocardiogram typically takes 30 to 60 minutes, although this duration can vary depending on the type of test and individual patient factors. Upon receiving the diagnosis of a heart disease, concerns arise regarding the test, like how long it takes, its cost, and whether their insurance will cover it. 

‍

Many patients associate the complexity of the disease with the duration of the test; the longer it takes, the more complicated the disease is, presumably. 

‍

However, this is not always the case. Cardiac diagnostic tests, such as ECG and the routinely done echocardiogram, are exceptions since they are non-invasive and take a short time to complete.

‍

In this blog article, we will explore how long it takes to do an echocardiogram and the factors affecting the duration of the test.

‍

What is an Echocardiogram?

It is an ultrasound of the heart, which provides moving images of the heart. The images so obtained help us visualize how the heart's structure pumps blood.

‍

It is a non-invasive test in which the patient lies down on a table and a water-based gel is applied to their chest. A small handheld probe called a transducer is moved over the chest. The transducer records, displays, and transmits the images of the heart to the screen.

‍

It is performed to see the heart’s anatomy, the movement of various walls, and any anomalies, if present. It detects the proper opening and closing of valves and how efficiently the heart is pumping blood.

‍

What is the time required to perform different types of Echocardiograms?

The amount of time required by different echocardiograms depends on the complexity of the procedure. If we can accurately estimate the time required for the procedure, patient expectations can be effectively managed.

‍

A patient can be advised to undergo a specific type of echocardiogram, depending on their heart condition and the factors that affect it. The length of time taken also varies depending on the technician’s preparation and expertise, as well as the patient's level of cooperation.

‍

The different types of Echocardiograms require different times, which are detailed below.

1. Transthoracic echocardiogram (TTE) requires 30 to 45 minutes

2. Transesophageal echocardiogram (TEE) requires around 45 to 60 minutes. The time required for sedation and recovery is additional.

3. A stress echocardiogram requires 45 to 60 minutes, depending on how quickly the heart rate reaches the target level.

4. Foetal echocardiogram requires about 30 to 60 minutes. It is subject to the cooperation of the baby and his position.

Factors affecting the time required for taking any Echocardiogram

The duration of the echocardiogram is influenced by several factors, such as the:-

• Type of echocardiogram (transthoracic, transesophageal, or stress)
• Complexity of the case
• Experience of the sonographer or cardiologist performing the test

‍

Type of echocardiogram

• A transthoracic echocardiogram (TTE) is the most common type and typically takes the shortest time, ranging from 30 to 60 minutes.

• Transesophageal echocardiogram (TEE) requires inserting a probe down the esophagus to provide clear images. It takes up to 90 minutes. The time required usually depends on the patient's level of cooperation. Additional time is required for recovery from the gag reflex, as the procedure is performed under sedation.

• A stress echocardiogram combines an echocardiogram with exercise to assess heart function under stress. Usually, it requires an extra 20 minutes or more.

‍

Patient factors

• Patient body: Obesity or a large chest size can make it difficult to obtain clear images.

• Patient cooperation: If the patient finds it difficult to hold still or follow instructions, it takes longer.

• Coexisting conditions: Lung diseases and chest deformities impact image quality and the time required.

‍

Complexity of the case

• Normal vs complex cases. A simple echocardiogram for a healthy heart takes less time compared to an abnormality or a congenital heart defect. 

• Views and measurements, the number of views required, and the complexity of measurements needed may lengthen the duration.

‍

Operator's experience

• Trainees vs experienced professionals can do the test quickly.

• Institutional practices — the protocols followed by various institutions — can contribute to differences in timing.

What factors reduce the time taken for doing an Echocardiogram?

To perform an echocardiogram faster, use

• Better machines and smarter tools must be used

• Computer programmes that measure automatically

• Screens that are easy to use and speed up the process

‍

These improvements save time without affecting the accuracy of the test

‍

Optimising image acquisition and interpretation

• Update your instruments as the current technology is modified to provide better image quality. New technologies reduce operator variability and speed up the process.

• Automate measurements, streamline the process, and save time.

‍

Use automation and AI (artificial intelligence)

• Artificial intelligence reduces measurement and report creation time.

• Software that automatically quantifies cardiac measurements saves time compared to manual methods.

‍

Streamline the workflow

• Touchscreen ultrasound is easier to use and speeds up the operation.

• Minimise the time for repeated scans by taking accurate initial images.

• Ensure the patient is well prepared to reduce the time required for the procedure.

• Properly train the sonographers and staff to improve efficiency.

‍

Focusing on these areas reduces the time required for echocardiography procedures, which benefits both the patient and the staff.

Tips to ensure a smooth experience during an Echocardiogram

Before the test

We need to follow a beneficial schedule

• You must do yoga and meditation to calm anxiety before the test.

• One must follow the dietary instructions and avoid eating or drinking a few hours before the test, especially for a transesophageal echocardiogram.

• Always inform your doctor of any medications you are taking.

• One must wear comfortable, loose-fitting clothes.

• It is best to avoid tea, coffee, and cigarettes for the period of the test.

• One must arrive punctually for the test.

‍

During the test

• Inform the sonographer if you experience any discomfort or pain.

• One must follow all instructions about not moving and deep breathing properly.

• Be as still as possible to ensure clear images.

Conclusion

An echocardiogram takes 30 to 60 minutes to complete. Other factors that influence the time taken to complete the test include the expertise of the sonographer performing the test and the patient's level of cooperation. Advancements in machines that provide AI-powered solutions also significantly reduce the time required, enhancing both the speed and accuracy of heart assessments.
