Accelerated idioventricular rhythm injury. AIVR is generally considered to be a benign abnormal heart rhythm. It is typically temporary and does not require treatment. In the human heart the sinoatrial node is located at the top of the right atrium. The sinoatrial node is the first area of the heart to depolarize and to generate the action potential that leads to depolarization of the rest of the myocardium. Sinoatrial depolarization and subsequent propagation of the electrical impulse suppress the action of the lower natural pacemakers of the heart, which have slower intrinsic rates. The accelerated idioventricular rhythm occurs when depolarization rate of a
Diskless node as thin clients. Moreover, thin client computers are increasing in power to the point where they are becoming suitable as fully-fledged diskless workstations for some applications. Both thin client and diskless node architectures employ diskless clients which have advantages over fat clients (see above), but differ with regard to the location of processing. Diskless node A diskless node (or diskless workstation) is a workstation or personal computer without disk drives, which employs network booting to load its operating system from a server. (A computer may also be said to "act as a diskless node", if its disks are unused and
