Progressive changes in the beating rate of embryonic rat heart after grafting suggest that the original pacemaker system becomes suppressed and a new, stable one arises. We mapped electrophysiologic activity of em- bryonic heart grafted in oculo to determine pacemaker location. Selective interventions ...

Heartbeat项目最初的消息通信层被独立为新的 Heartbeat项目,新的 Heartbeat只负责维护集群各节点的信息以及它们之间的心跳通信,通常将 Pacemaker与 Heartbeat或者 Corosync共同组成集群管理软件, Pacemaker利用 Heartbeat或者Corosync提供的节点及节点之间的心跳信息来判断节点状态。 (2)Cluster Clue Cluster Clue 相当于一...

同时,对于任何形式的软件资源,通过为其自定义资源启动与管理脚本(资源代理),几乎都能作为资源对象而被Pacemaker管理。此外,需要指出的是,Pacemaker仅是资源管理器,并不提供集群心跳信息,Pacemaker的心跳机制主要基于Corosync(或Heartbeat)来实现。 Pacemaker内部结构...
Pacemaker是 Linux环境中使用最为广泛的开源集群资源管理器, Pacemaker利用集群基础架构(Corosync或者 Heartbeat)提供的消息和集群成员管理功能,实现节点和资源级别的故障检测和资源恢复,从而最大程度保证集群服务的高可用。从逻辑功能而言, pacemaker在集群管理员所定义的资源规则驱动下,负责集群中软件服务的全生命周期管理,...

Bradycardia and tachycardia associated with multiple arrhythmias were present in all cases; heart rate was less than 40 beats/min in 58 percent of patients and more than 140 beats/min in 71 percent. Conduction abnormalities were present in 61 percent. After insertion of a demand pacemaker, 27 ...
