This case report highlights the diagnostic value of an implantable loop recorder (ILR) in two elite athletes, one with recurrent palpitations, the other with a history of bradycardia and syncope. 1 Thus, prompt evaluation of an athlete with a possible arrhythmia as the cause is warranted. Sudden cardiac arrests in athletes are high-profile events and the risk of sudden cardiac arrest has been shown to be greater in athletes versus the general population. Manuscript received March 14, 2016, Final version accepted May 9, 2016.Īddress correspondence to: Ian Law, MD: Stead Family University of Iowa Children’s Hospital, 200 Hawkins Drive, Iowa City, IA 52242–1083. The authors report no conflicts of interest for the published content. loop recorders, supraventricular tachycardia, ventricular tachycardia. In both instances, the ILR facilitated a diagnosis, which ultimately lead to appropriate and timely management. Here we highlight the value of the implantable loop recorder (ILR) using two cases involving collegiate athletes. In order to reduce mortality without unnecessarily taking healthy athletes away from competition, a useful diagnostic test is needed. Sudden cardiac arrests in athletes due to arrhythmias have become much more high profile, and the relative risk of sudden cardiac death has been shown to be greater in athletes when compared to non-athletes.

"Once discovered, treatment can be prescribed to prevent future strokes, giving you and your loved ones peace of mind and quality of life.A Tale of Two Athletes: The Value of Implantable Loop Recorders in Elite AthletesĪNDREW HULL, BS, FRANK CANADY, BA, PRASHANT BHAVE, MD and IAN LAW, MD "These monitors are more than twice as likely to detect a dangerous heart rhythm that is silently planning to cause a stroke," Dr. The implantable device records heart rhythms and transmits them to your doctor at regular intervals, allowing the physician to pick up arrhythmias before the patient is aware of them. They have replaced the slightly larger Holter monitors that measure and continuously track your heart's activity for shorter periods of time from the outside of your body. Implantable heart monitors have been around since 2014, and are able to continuously transmit data about your heart rhythm to your physician for up to three years. 5 cause of death in the U.S., the benefits can be tremendous. "Since Afib is often infrequent and unpredictable, this may require an implantable heart monitor that can help us easily monitor what your heart is doing at all times."īecause stroke is the No. "If you or a loved one has had a stroke, and we suspect Afib as the culprit, we may want to monitor your heart to determine how often and how long Afib is occurring," Dr. One possibility is Afib, when your heart's upper chambers and lower chambers are beating out of sync, often with no symptoms. Often called the silent killer, strokes occur when something blocks blood flow to the brain or causes bleeding in the brain. Knowing that a patient has Afib offers options to reduce stroke risk. Placed on a blood thinner, the woman made a complete recovery and today has the chance to avoid future strokes and remain actively engaged in her day-to-day activities. Called a loop recorder, the device allowed the patient's cardiologist to continuously track the woman's heart rhythm, and within three months, he diagnosed atrial fibrillation (Afib). Zach decided to implant a heart monitor about the size of a flash drive just beneath the skin in the patient's upper left chest. "This was quite alarming because she could potentially suffer another stroke that could disable or even kill her."ĭr. "Prior to her release from the hospital, we did an extensive workup that didn't reveal the cause of her stroke," said Victor Zach, MD, a neurointensivist who's an independent member of the HonorHealth medical staff. Fortunately, she gets to the ER immediately, is diagnosed with a stroke and is treated with a clot-busting medication. An active 62-year-old woman suddenly experiences slurred speech, an inability to produce new words and paralysis of her right arm.
