PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.

If the block is not vagal in nature, the patient should receive a pacemaker. There was a randomized trial to determine whether pacemakers could benefit patients with vasovagal syncope, aptly named The North American Vasovagal Pacemaker Study (VPS). In the repeat study (VPS II), EVERY patient had an implanted pacemaker.
