    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.

    Just a guy holding up his own heart after a heart transplant. No big deal.



    Heart Blocks

    decellularized "Ghost" Heart The cells are removed by a chemical process, leaving only Extracellular matrix, so the new cells of the transplantee, which match the DNA, can be grown on this heart, so the rejection of the organ doesn't happen. It's still in the experimental stage, but it is promising.

    Heart attack triggers.

    Cardiac tamponade occurs when fluid [blood] builds up in the pericardial sac (the sac that surrounds the heart.) This fluid compresses the heart. Enough blood cannot be pumped in and out of the heart - this decreases the cardiac output, causing one million problems. This is a life-threatening condition. Signs & Symptoms -BP decreases, because you are hemorrhaging; CVP [pressure inside the heart] increases, because blood is squeezing the heart; heart sounds are distant and muffled [all th

    Heart Failure


    This is just crazy.. A human heart destined for transplant lies cradled in a TransMedics Organ Care System. The device can keep a heart warm and beating—and viable for many hours longer than the conventional method for handling donor hearts: immersion in a saline solution and packing in ice. -national geographic.

    The heart's "master pacemaker" is the sinoatrial (SA) node (Upper R-atrium). Here electrical impulses quickly spread through the R L atria. The atrioventricular (AV) node (Lower R-atrium) is stimulated. The heart's lower chamber (the ventricles) fill with blood contract. The R Bundle is His are stimulated next followed by the Purkinje fibres. The ventricles contract the blood is ejected. Any abnormalities in the heart's electrical pacing system results in a cardiac arrhythmia.
