Praxis crankstel Alba M30 DM (direct mount) X-spider. Met zijn 30 mm aluminium als en solide crankarm is de Alba breed inzetbaar. De 2x kettingbladen hebben Cold Forged (koud gefreesde) tandbladen die zorgen voor een hardere en betere duurzaamheid tegen slijtage dan CNC gefreesde tandbladen. Daarnaast biedt dit proces het voordeel dat de Levatime eenvoudig kan worden toegepast. LevaTime is een unieke techniek waarbij alle tanden een eigen vormgeving hebben, dit zorgt ervoor dat een ketting perfect van het binnen- naar het buitenblad kan schakelen. Het single kettingblad beschikt over de WAVE-technologie, waardoor de tanden om-en-om links en rechts uitgelijnd zijn zorgt voor een zijdelingse spanning op de ketting wat er voor zorgt dat de ketting op het voorblad blijft liggen. De armen van de cranks zijn verkrijgbaar in de lengtes 160, 165, 170, 172.5 en 175mm. Behuizing in de combinatie 48/32, 50/34, 52/36 tands. Geschikt voor 10, 11 en 12 speed kettingen.

Info not to be found elsewhere ...
Format: Paperback
I am a cardiologist in my 50s. I have long been interested in hemodynamics and have an extensive home file system and library of Cardiovascular related books and journal articles. I thought I understood hemodynamics and tracings very well. However this book is a treasure trove of info that simply cannot be found in other publications. It has been a very worthwhile purchase. Highly recommended. This is best suited for cardiology fellows and beyond in my opinion. This info is simply not to be found elsewhere. It is as if a grey haired attending is pointing out minutiae to you that you had not realized was buried in the tracings. Well written and easy to digest. It is best to have a good understanding of hemodynamics and waveforms before reading this though. The correlation with ECHO and diastolic issues is also very good. (This book should be required reading for all cardiology fellows - invasive or noninvasive)

Excellent
Format: Paperback
As a second-year cardiology fellow, I used to get very confused with hemodynamics during my cath and CCU rotations. This book is a gem, it is clear and logically written, has great explanations of waves and great illustrations. The constrictive pericarditis, valvular disease, and FFR chapters are impressive with echocardiographic and physiologic correlations. I actually liked everything I read, like the nice differentiation between the pressure tracings of various chambers. Some of it requires multiple reads but it is worth it. I realized that I had missed a great deal of the basic understanding of pressure tracing configuration, wedge pressure, shunts.
There are also over 50 cases in a test-answer format probably covering and reviewing most hemodynamic topics. It is like 2 books in 1.

Bought this book. Good content. However my copy is in black and white. There are references to colored arrows. I later learned that others have a colored copy.

AMAZING BOOK!!!!!! WOW!!! everything you need to know about hemodynamics.
This book explains the concepts with graphing, images. It also summarizes the key points.
I wish I have read that book sooner.
I could not believe it that in 1 book I found all the information I needed for the cardiology boards and my daily practice.
Thank you o ugh Dr. Hanna for taking the time to write this book. Much Thanks!!!!
