These impacts range from baseballs and soccer balls to a closed fist or vehicular accident. The arrhythmic outcome is a result of mechanoelectro coupling, in which a mechanical stretch of cardiac tissue results in electrical instability of the heart. There is a wide range of clinical presentation in the arrhythmias documented in\n                    <jats:italic toggle=\"no\">commotio cordis<\/jats:italic>\n                    cases, furthering our understanding of this complex mechanism that presents unique diagnostic and treatment challenges.

This clinical review has made significant steps toward building a global repository by including 100 new case reports and synthesizing all epidemiological data from 434 published case reports, which include 302 cases in sports and 132 cases in nonsporting events, including violence, motor vehicle accidents, and daily activities. Male dominance across these cases reports is clearly established, as men make up 94% of cases in sports and 93% of nonsporting events. Treatment using cardiopulmonary resuscitation and automated external defibrillators has increased survival rate &gt;50% in recent years. Meanwhile, preventative measures have focused on improved chest protection in sports, simulation studies in human models, and the effectiveness of safety baseballs and safety regulations such as
