Depending on the clinic or hospital’s protocol, patients may be asked to lie on their left side or on their back during the examination. Once the patient is comfortably positioned, the healthcare provider will attach small electrode pads to their chest, allowing for continuous monitoring of the heart’s electrical activity during the procedure.
This is done using an electrocardiogram (ECG) monitor, which displays the heart’s rhythm and helps to correlate the images obtained during the echocardiogram. The ECG monitor ensures that the echocardiogram is precisely timed with the different stages of the cardiac cycle.
Echocardiogram Process:
The echocardiogram procedure takes place in a darkened room to optimize image quality. The healthcare provider conducting the examination will apply a warmed, water-based gel to the patient’s chest.
This gel facilitates the transmission of ultrasound waves and helps to eliminate air bubbles that may interfere with image clarity. The gel is typically warm, ensuring patient comfort throughout the procedure.
Once the gel is applied, the healthcare provider will position the transducer probe on various locations of the chest to capture different views of the heart. The transducer emits ultrasound waves and receives the echoes bouncing back from the heart, creating real-time images on a monitor.
These images show the heart’s different structures, such as the chambers, valves, and blood vessels. During the examination, patients may be asked to change positions or hold their breath temporarily to optimize image quality for specific views or to capture certain structures more accurately.
The healthcare provider conducting the echocardiogram will provide clear instructions on when to breathe normally or hold their breath. It is important for patients to follow these instructions to ensure optimal imaging and accurate assessment of the heart’s function and structures.
In certain cases, an echocardiogram may require the use of intravenous (IV) contrast. This contrast agent enhances the visualization of blood flow within the heart and blood vessels, aiding in the detection of any abnormalities.
If IV contrast is necessary, a small needle will be inserted into a vein in the patient’s arm or hand, and the contrast agent will be administered slowly. The contrast agent may cause a warm sensation or a metallic taste in the mouth, but these sensations are temporary and subside quickly.
Post-procedure Steps:
After the echocardiogram is complete, the healthcare provider will remove the gel from the patient’s chest using disposable towels or wipes. The gel is water-based and easy to remove, ensuring a comfortable and clean experience.
Any remaining gel residue can be wiped away with a towel or easily washed off with water. The electrode pads used for the ECG monitoring will also be removed by the healthcare provider.
These pads may leave a sticky residue on the skin, but this can be easily wiped off with a wet towel or washed away with water. Patients can then dress and resume their usual activities without any specific post-procedure care requirements.
Following the echocardiogram, patients can typically return to their regular diet and activities unless instructed otherwise by their healthcare provider. In some cases, additional instructions may be given depending on the results of the examination or the specific condition being evaluated.
