What is an example of a noninvasive cardiology procedureservice?
An example of a noninvasive cardiology procedure is an echocardiogram, which uses ultrasound waves to create images of the heart's structure and function. This test helps assess heart conditions without the need for any surgical intervention. Other noninvasive services include stress testing and electrocardiograms (ECGs), which monitor heart activity during exercise or at rest. These procedures are essential for diagnosing and managing various cardiovascular diseases.
What is the origin of the term Electrophysiology?
Electrophysiology is of Greek origin. It is the study of electrical properties of biological cells and tissue. It measures voltage change or electric currents on many scales like ion channel protein to organs like the heart.
What is the approximate cost in the US to do an electrophysiology study?
Mine was billed at $18, 425 for the evaluation with additional charges of $4,704 for "intracardia electrophysiology" and $5,428 for "Stimulations, pacing of the heart." The insurance company has a contracted price for less than that, however.
What procedure is involved in an electrophysiology study of the heart?
four to 10 electrodes are located on the end of the catheters, which have the ability to send electrical signals to stimulate the heart (called pacing) and to receive electrical signals from the heart
What are the example of contribution in medicine?
Examples: discovery of antibiotics, heart transplants, dental implants, noninvasive surgery, anesthesia, vaccinations etc.
Is a noninvasive diagnostic method that uses ultrasonographic images to detect the presence of heart disease or valvular disease?
Yes. Color Doppler Ultrasonography gives accurate description of presence of heart disease or valvular heart disease.
Often used to examine parts of the body including the heart and liver?
An ultrasound is often used to examine parts of the body including the heart and the liver. The ultrasound allows for a noninvasive look at the organs.
Under what circumstances may an electrophysiology study of the heart be recommended?
when the standard EKG, Holter monitor, event recorder, stress test , echocardiogram, or angiogram cannot provide enough information to evaluate an abnormal heart rhythm (arrhythmia).
What consideration underscores the need for electrophysiology study tests?
The normal function of the heart depends on its electrical activity, and the effect of this activity on each of its cells. When a heart is diseased, impaired electrical activity is often the factor that leads to sudden death

Why is the plateau phase so important to the electrophysiology of the heart?
The plateau phase, primarily occurring during the cardiac action potential, is crucial for the heart's electrophysiology as it prevents premature contractions and ensures a prolonged refractory period. This phase, characterized by a balance between calcium influx and potassium efflux, allows for sustained contraction of cardiac muscle, facilitating effective blood pumping. Additionally, it helps to coordinate electrical activity across the heart, ensuring that the atria and ventricles contract in a synchronized manner. Overall, the plateau phase is vital for maintaining a stable heart rhythm and optimal cardiac function.
