[Phase analysis of the normal and postectopic left ventricular contractions in nonejection click-telesystolic apical murmur syndrome]. 1979

N Kolev, and K Denchev

ECG, PCG, CSG and ACG were synchronously recorded in 25 patient with non-expulsion click syndrome -- telesystolic murmur as well as in 62 cardiac healthy subjects. With the investigation of the systolic and diastolic intervals, a prolongation of the transformation period was established (Q--1 = 72 +/- 12 msec) and a shortening of the isovolumetric relaxation (A2--0 = 63 +/- 10 msec). The ratio PPE/LVET (period prior to expulsion/left venticular expulsion time) is normal in patients with nonexpulsion click -- telesystolic apical murmur but the comparison of PPE/LVET with a normal contraction with that of the first post extrasystolic contraction shows a statistically significant shortening. The ratio PPE/LVET in prolapse of the mitral valve prior to extrasystole is 0.39 +/- 0.02, and during the first contraction with intensified stroke after a compensatory pause is 0.31 +/- 0.03 (p less than 0.02). The possibility for explanation of the changes in phase analysis are discussed and a conclusion is drawn that they reflect the existence of deviation in the left ventricular mechanics and hemodynamics in case of mitral valve prolapse.

D008945 Mitral Valve Prolapse Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.

D010701 Phonocardiography Graphic registration of the heart sounds picked up as vibrations and transformed by a piezoelectric crystal microphone into a varying electrical output according to the stresses imposed by the sound waves. The electrical output is amplified by a stethograph amplifier and recorded by a device incorporated into the electrocardiograph or by a multichannel recording machine. Phonocardiographies
