For pressure pulses to be transmitted to vital organ vascular beds, minimum loss through vascular branching junctions is necessary. Experimental measurements of pulse wave velocities and cross-sectional areas allowed branching reflections to be quantified. Wave reflections at normal aorto-iliac junction is minimal. Increased reflection occurs when the branch vessel is either narrowed or occluded. Also, geometric factors dominate over elastic factors in determining the amount of pulse wave reflections at the aorto-iliac junction.

    The article offers information on Watson's water hammer pulse (whp). Also known as collapsing pulse, collapsing pulse or pulsus celer, whp is used to describe a pulse with a rapid upstroke and descent, characteristically described in aortic regurgitation. The method to elicit the water hammer...

    A definition of the term "pulsus" is presented. It refers to a pulse. Various categories of pulses include celler, differens, and paradoxus. Differens is a condition in which the pulses on either side of the body are of unequal intensity. It is seen sometimes in aortic dissection, or in...

    We perform the in situ characterization, by second-order optical autocorrelation, of femtosecond pulses transmitted by near-field optical probes. We demonstrate that transmission through hollow pyramid probes with diameter down to 65 nm has negligible effects on the duration of pulses as short...

    The article explains the use of the Zang-fu Model of pulses. The upper part of the position is the Fu or hollow organ and the lower half is the Zang or solid organ. The use of Front and Back may be slightly different than the classics. Typically Front and Back are interpreted to mean upper and...
