  The Haywire Heart with Dr. John Mandrola, Lennard Zinn, and Chris Case It’s been said that if a little does a good job, then a lot is even better and too much is probably just right. However, evidence indicates that too much exercise, like that experienced by years of endurance sports, can lead to what is known as “athlete’s heart” - a host of conditions easy for physicians to misdiagnose. In this episode, we are joined by Dr. John Mandrola, Lennard Zinn, and Chris Case, the co-authors of The Haywire Heart. Their book details numerous case studies, including that of co-author Lennard Zinn and the event that nearly killed him. Today, Lennard shares the story of his initial cardiac episode, diagnosis, and his new perspective on fitness as he still participates in endurance sports. Dr. John Mandrola is a cardiac electrophysiologist and an active cyclist who had atrial fibrillation. He works in a private cardiology practice where he specializes in heart rhythm disorders. He is Chief Cardiology Correspondent for
