			These factors influence the chance of commotio cordis:[7]
- Direction of impact over the precordium (precise area, angle of impact)
 - Total applied energy (area of impact versus energy, i.e., the kinetic energy of the projectile {\displaystyle E_{\text{k}}={\tfrac {1}{2}}mv^{2}}
		
		
	
	)
 - Impact occurring within a specific 10- to 30-millisecond portion of the cardiac cycle. This period occurs in the ascending phase of the T wave, when the ventricular myocardium is repolarizing, moving from systole to diastole (relaxation).
 
- The increase in heart rate (exercise tachycardia) may double the probability above (e.g., with 120 beats per minute the cardiac cycle shortens to 500 milliseconds without fundamentally altering the window-of-vulnerability's size)
 - Relative exercise-induced hypoxia and acceleration of the excitoconductive system of the heart make it more susceptible to stretch-induced ventricular fibrillation.[8]
