cavities, as the pericardial friction-sounds. M., False. 

 See M., Cardio-pulmonary . M., Flint's, a murmur 

 occasionally heard at the apex in aortic regurgitation. 

 It is sometimes presystolic in time and is probably due 

 to the fact that on account of the extreme ventricular 

 dilatation the valves cannot be forced back against the 

 walls and produce a relative narrowing of the auriculo- 

 ventricular orifice. See also Signs and Symptoms, Table 

 of. M., Friction, a murmur or sound produced by 

 the rubbing of two inflamed serous surfaces upon each 

 other. M., Functional, a cardiac murmur occurring 

 from excited action of the heart, without any structural 

 change in the valves or orifices. M., Funic. See 

 Souffle, Funic. M., Heart, an abnormal sound pro- 

 duced within the heart or on its surface. M., Hemic, 

 a sound believed to be due to changes in the quality or 

 amount of the blood, and not to lesions of the vessels 

 or valves. M., Indirect, one produced by the blood 

 flowing in a direction contrary to the normal current. 

 M., Inorganic, amurmur not due to valvular lesions ; 

 a hemic or a functional murmur. M., Metadias- 

 tolic. See M. , Post-diastolic. M . , Metallic, a murmur 

 sometimes heard in pneumopericardium, and having 

 a metallic quality. M., Mitral, a murmur produced 

 at the mitral orifice. M., Musical, a heart-murmur 



having a musical quality. M., New Leather. See 

 Bruit de cuir neuf. M., Organic, a murmur due to 

 structural changes in the heart. M., Pericardial, a 

 friction-sound produced by the rubbing of the pericar- 

 dial surfaces upon each other. M., Placental. >tv 

 Souffle, Uterine. M., Post-diastolic, a murmur heard 

 immediately after the second sound of the heart. M., 

 Pressure, usually a vascular murmur and due to coal 

 pression of the vessel, as with the stethoscope. M., 

 Presystolic, a murmur heard at the end of the dias- 

 tolic pause, just before the first sound. It is the com- 

 mon murmur of mitral stenosis. M., Pulmonary, a 

 murmur produced at the pulmonary valve. M., Rasp- 

 ing, a rough murmur. M., Reduplicated, a redupli- 

 cation of the first or second heart-sound, due usually to 

 an asynchronous action of the two sides of the heart. 

 It occurs in conditions of increased resistance in the 

 systemic or pulmonary circulation — as in chronii 

 litis and in emphysema. It is quite frequent in mitral 

 stenosis and in pericarditis. M., Respiratory, the 

 sounds resulting from the passage of the air through 

 the bronchial apparatus during inspiration and ex- 

 piration. M., Sawing, a long, harsh heart nun 

 mur. M., Scapular, the systolic murmur of mitral 

 regurgitation transmitted to the angle of tl
