Brief Summary:
The purpose of this study is to determine whether or not the intravenous adenosine test readily identifies patients with unexplained syncope who would benefit from permanent pacemaker implantation.
Detailed Description:
The investigation of syncope (transient loss of consciousness with loss of postural tone, collapse and spontaneous recovery) varies widely, is often lengthy and frequently expensive. The intravenous adenosine test has been used in the investigation of syncope and is cheap, safe and free of serious side effects. However, it is unclear what diagnosis the test unearths. There is some evidence that the test readily identifies bradycardia pacing indications.
In this study we plan to perform the adenosine test and implant a pacemaker should the test be positive. In half of the patients we will turn the pacemaker "on" and in the other half the pacemaker "off". The groups will swap over after six months. During this time we will assess the number of syncopal episodes. Also, in those who have a negative adenosine test we will implant a loop recorder to try to discover the cause of syncope.
