Boyd usually splits the creation of a novel into two phases: research and writing. The first phase of "Any Human Heart" took 30 months as he carefully
Short QT syndrome activation lose their pumping ability - fibrillation of the cardiac atria in atrial fibrillation leads to an irregular pulse, and fibrillation of the cardiac ventricles in ventricular fibrillation renders the heart unable to pump blood at all. There are several possible mechanisms by which short action potentials might promote fibrillation. The link between these mechanisms is how the duration of the action potential influences how frequently a heart muscle cell can be excited. A shorter action potential generally allow a heart muscle cell to be excited more frequently - the refractory period is shorter. The first mechanism, referred to as
