The Cardiogram of Mitral Restenosis.
The cardiogram of mitral stenosis, with emphasis on right ventricular hypertrophy and P wave changes before and after mitral valvotomy has been studied previously by Mounsey (1957) and by Rodriguez Torres et al. (1959). Cardiographic evidence of right ventricular hypertrophy that recurred after valvotomy and increased when restenosis occurred has been presented by Wilcken (1960). The present st...
متن کاملThe Normal Apex Cardiogram
T HE apex cardiogram was described in 1878 by Marey.' With the exception of its utilization in the timing of the opening snap of the mitral valve 2 3 and in the identification of the third and fourth heart sounds,4-6 it has been used only infrequently as an aid in timing cardiac phenomena. Technical difficulties in its recording have obstructed its more universal application and, more particula...
متن کاملDual-frequency multifunction lidar
The design and performance of a continuous wave dual-frequency multifunction lidar system is presented. The system is based on the use of the nonlinear dynamics of an optically injected semiconductor laser. Under proper operating conditions, the laser emits a dual-frequency beam with a broadly tunable microwave separation. The two optical lines are coherently locked to each other using an exter...
متن کاملMultiFunction Threshold Gates
Threshold logic gates, up to now, generally have been presumed to provide a single function of the input variables. The threshold gates that have been integrated [I1]-4] were naturally double-sided and provided complementary outputs or, more specifically, complemented dual outputs. This paper shows that the inphase and out-of-phase outputs can, in fact, be designed to provide grossly different ...
متن کاملImplicit Multifunction Theorems
We prove a general implicit function theorem for multifunctions with a metric estimate on the implicit multifunction and a characterization of its coderivative. Traditional open covering theorems, stability results, and sufficient conditions for a multifunction to be metrically regular or pseudo-Lipschitzian can be deduced from this implicit function theorem. We prove this implicit multifunctio...
