Dr Jonathan Kim discusses sudden cardiac arrest and vital protocols for detecting cardiovascular risks in competitive athletes.

As a result, there can be flaws in the data that report these types of events."What's the study design?" A retrospective study design has limitations."How do you identify all the right cases? How do you know you've identified all the right cases?" That's the numerator.
One question that comes up frequently is,"What's the most common cause of sudden cardiac death in a young competitive athlete?" As I mentioned, for the older athlete, it is usually due to underlying ischemic heart disease. For the younger athlete, at present, it's most common that you can't find a cause, where the autopsy for a deceased athlete is normal.
First, you have to remember that there are some conditions that an ECG can't pick up, such as problems with coronary artery origins, what we call anomalous coronary arteries; problems with the aorta; problems with the heart valves; and, of course, myocarditis, because many times, an athlete is screened before they could be afflicted with myocarditis.
Those are the things that have to be considered. To recap, I would say — this is my opinion — that screening ECGs are certainly reasonable because we know we're going to pick up more conditions. Ultimately, that's really going to improve the medical care if you can identify risk factors that require focused cardiac care. But you should only integrate ECG screening if you have thought carefully through these processes.
