A dual chamber pacemaker paces the atrium and ventricle. A biventricular pacemaker paces both ventricles. An implantable cardioverter-defibrillator can function as a pacemaker would. In addition, if it detects ventricular tachycardia or fibrillation, it sends out a shock to reset the heart to a normal rhythm.
Black and off-white. It's in the same great style of the city posters, but this time the map is of all the valves, atriums and whatnot that make up the human heart. We love anatomical models and prints, so this is right up our alley. Wouldn't one of these be a nice way to say 'I heart you'? We think so. Available at Ork Posters.
Valentine's Heart Poster por Rachelignotofsk. This is the 1st cardiac illustration I've seen that serves both a truly artistic and educational purpose! Love it! And maybe my friends won't make fun of me anymore if I replace my current nerdy-medical wall hangings with these, LOL.
