The size of the rupture varies from a mere sht to an ex-tensive lacerated opening; in some cases, the external open-ing { the opening into the pericardium) is smaller than theinternal. The effect of the rupture is, of course, to allow the escapeof blood from the cavity of the heart into the sac of thepericardium. When the laceration is extensive and a largequantity of blood escapes, death may be instantaneous; inother cases, more especially when the rupture is a small one,and the direction of the rupture oblique, the patient may.
