Syncope Due to Severe Coronary Artery Spasm-Related Bradyarrhythmias in Variant Angina
Clinical Scenario
Bradycardia / Bradyarrhythmia
This protocol addresses patients with variant angina who develop syncope as a direct consequence of severe coronary artery spasm-related bradyarrhythmias — a high-risk presentation requiring targeted rhythm management.
Treatment Approach
When severe coronary artery spasm causes bradyarrhythmias leading to syncope, a device-based intervention targeting the rhythm disturbance is central to management. The full structured protocol details the specific indications and decision pathway.
Complete regimen, selection criteria, and sequencing available via the protocol below.

In patients with syncope or cardiac arrest caused by CAS-related tachyarrhythmias, or even bradyarrhythmias, implantation of an ICD or pacemaker, respectively, should be considered according to the risk of recurrence and efficacy of vasodilator therapy.
Similar considerations may apply to pacemaker implantation in patients who develop CAS-related syncope due to the development of severe bradyarrhythmias.
