HRS: School-Wide ECG Screening Feasible
SAN FRANCISCO -- A program that screened all students at a Chicago-area school for heart problems was clinically successful, but drew criticism for its broad scope and expected costs.
Among the more than 50,000 teens screened with electrocardiograms at school through the program, 2.16% showed significant abnormalities that required further follow up, Joseph C. Marek, MD, of the Midwest Heart Foundation in Oakbrook Terrace, Ill., and colleagues reported.
"It's feasible to do," Marek noted during his presentation at the Heart Rhythm Society meeting.
Pre-participation screening for student sports may prevent cases like that of high-school basketball player Wes Leonard, who died from sudden cardiac arrest in early March moments after scoring the winning shot for his team.
But most teens who do not participate in school sports are physically active even if just in gym class, Marek pointed out.
"Sports participation is a magnifier of these conditions [that predispose to sudden cardiac death]," he told MedPage Today , "but is a kid cheerleading any less important than the varsity quarterback? I don't think so."
While a single preventable death in any child is a tragedy, "the question has always been how much is society willing to spend to avoid that tragedy," Arthur Garson, MD, MPH, of the University of Virginia in Charlottesville.
Aside from the cost for screening, the costs associated with further testing, anxiety, and restriction from sports for false-positive test results have been controversial, as Garson and other experts explained via email to MedPage Today .
Based on prior studies, ECG screening for the number of teens reported in the study could have been expected to produce about 1,500 false positives sent for further testing for every potential life saved, noted Barry Love, MD, director of pediatric electrophysiology at Mount Sinai School of Medicine in New York City.
The positive predictive value for an ECG abnormality as defined by Marek's group would be at most 10%, agreed Michael J. Ackerman, MD, PhD, of the Mayo Clinic in Rochester, Minn., and president of the Sudden Arrhythmia Death Syndromes Foundation.
Given the time and money needed to unwind the true diagnosis in these cases, this "collateral damage" rate may be unacceptable, he suggested.
Also, many of the at-risk students identified in such a screening program might have been caught later through other encounters with the healthcare system, noted Glenn Wetzel, MD, PhD, director of the arrhythmia service at Le Bonheur Children's Hospital in Memphis, Tenn.

The ECGs were administered by trained community volunteers and read by cardiologists. This strategy helped keep costs low, Marek noted. He estimated that an ECG runs about $9 alone, or less than $20 using the Medicare reimbursement rate for the
One of the main objections to doing extensive ECG testing has been cost, but Marek said the tests in his study cost less than $10 each. For the study, his team raised money for the testing through community donations. Marek said that some also feared

Echocardiogram (ECG) – Procedure, Test, Types and How to read EKG
What is Echocardiogram?
The echocardiogram is a device used in the medical field that sends out ultrasound waves at the cardiac cavity and the heart itself, it then gathers the reflected sound waves and translates it into live visual representations of the heart. It can also be termed as cardiac echo, which is a diagnostic test that visualizes the heart using ultrasound waves. Its meaning can actually be deduced from its name, echo means the reflection of sound, cardio pertains to the heart muscles, and gram is a term used to signify measurement or visualization, thus the term echocardiogram.
An echocardiogram test can display images of your cardiac muscle in different ways like one dimensional and 2 dimensional slices of the heart, and as the device’s model becomes more advanced, more options are made available like the three dimensional real time visualization. The single dimension imaging or M-mode of the machine is used for obtaining the precise dimensions of the different heart valves and chambers, while the two dimensional visualization available in more advance models allows the viewing of images that depict cross sections of pounding cardiac muscles including its valves, chambers, and vessels.
Echocardiogram procedure
When undergoing an echocardiogram, you have to understand that this test can only be performed accurately by trained professionals such as physicians with cardiology specialization or training, specialized cardiac sonographers, and cardiac physiologists. There is no special preparation required when going for this test, you will be asked to lie down on the examination table and remove the clothing for your upper body, a hospital gown may also be provided. Wires with electrodes will then be attached to certain points of your chest up to the armpits, the electrodes are usually attached to your skin via suction.
After that, a clear gel will then be slathered unto your skin to allow better sound conduction of the transducer, this is the component of the echocardiogram machine that transmits ultrasound waves and captures the resultant echoes to be transmitted to the main body of the echocardiogram, you may feel a slight pressure from the transducer as the cardiac sonographer needs to apply some pressure for better visualization. Certain instructions may be given to you as the test progresses, such as rolling over to a side-lying position and changing your breathing patterns. All the things being visualized is automatically being recorded on paper and video by the machine to be reviewed later by your attending physician.
