athlete's heart,

common term for an enlarged heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function

The human heart is a pear-shaped structure about the size of a fist.

 associated with repeated strenuous exercise. As a result of the increased workload required of it, the heart will increase physiologically by enlarging chambers and muscle mass, or hypertrophy by enlarging the size of the chambers and increasing the volume of blood pumped per stroke. Consequently, the heart has to contract less frequently and at rest will beat as few as 40 times per minute as compared with an average number of 70 beats in a normal heart. The condition is not pathological, and there is generally no danger of cardiac disability arising from it.

While considered to be physiologically benign, it is important to differentiate the athlete's heart from a number of inherited cardiac pathologies, which may predispose the apparently young and healthy athlete to serious arrhythmia and the potential for SCD (12).
Roughly 40% of highly trained individuals have abnormal ECG patterns that are labeled athlete's heart, and this condition is not restricted to the elite athlete category, said Dr.
Since the phenotypic expression of hypertrophic cardiomyopathy is variable, and not uncommonly includes patients with mild and localized left ventricular hypertrophy, the differential diagnosis with physiological remodeling of athlete's heart not uncommonly arises (45).
Physicians should suspect HCM rather than athlete's heart if the patient has an unusual pattern of left ventricular hypertrophy, a small left ventricular cavity, left atrial enlargement, an unusual ECG pattern, or abnormal left ventricular filling.
The heart of moderately increased mass and high working capacity triggered by the repetitive cardiac overload which is induced by regular exercise training without any serious valvular or other functional disorders, is called an athlete's heart (Firoozi et al.
Each athlete's heart rate, skin temperature and movements will be monitored over time using a Mini-Logger device positioned on the body.
has developed several proprietary technologies that accurately measure and display an athlete's heart rate, even during vigorous exercise, without the need of a chest strap transmitter or any other extraneous cuffs or clips.
The solution is built on a patented algorithm that measures the athlete's heart rate by calculating 64,000 data points per second.
If the problem is that EKGs are likely to be misread, the solution is to make sure that they are performed by skilled cardiologists who can either take into account the normal remodeling of an athlete's heart, or order follow-up tests that will confirm a diagnosis.
This condition is described as athlete's heart or exercise related myocardial remodeling, and it is characterized by increases in the chamber size, wall thickness and left ventricular (LV) mass.
