Pacemaker 由 Novell 支持,SLES HAE 就是用 Pacemaker 来管理集群,并且 Pacemaker 得到了来自Redhat,Linbit等公司的支持。它用资源级别的监测和恢复来保证集群服务(aka. 资源)的最大可用性。它可以用基础组件(Corosync 或者是Heartbeat)来实现集群中各成员之间的通信和关系管理。它包含以下的关键特性:...
16, but also in part on autonomic blockade17, the day-night rhythm in heart rate is attributed to high vagal tone during sleep and changes in ionic conductances (as a result of apost-translationalregulation of the corresponding ion channels) in the pacemaker of the heart, the sinus node. ...
Pacemaker, electronic cardiac-support device that produces rhythmic electrical impulses that take over the regulation of the heartbeat in patients with certain types of heart disease. A healthy human heart contains its own electrical conducting system ca
There is a question: how highly available will be such high available cluster? To research this was developed a test bed, which imitates failures of a cluster node, waits for recovery, fixes failed node and cyclically continue testing.
Electrophysiologic map- ping with two microelectrodes showed that each embryonic heart graft developed a primary pacemaker within the region of contact with the host iris. These single, primary pacemakers were found in the centers of graft-iris junctions both in grafts that originally contained the ...
Two cases of young children with frequent severe breath-holding spells complicated by prolonged asystole and seizures are reported. A ventricular pacemaker was implanted in each child, and both have subsequently remained free of syncope, although they continue to exhibit breath-holding behaviour.关键词...
