Background-Device implant pocket hematoma is a recognized complication after permanent pacemaker (PM) and implantable cardioverter-defibrillator (ICD) implantation. Pocket hematoma is associated with local discomfort, an increased risk of infection, and may require surgical intervention or lead to lengthier hospital stays. The purpose of the study was to identify the clinical factors associated with hematoma formation after PM or ICD device implantation. Methods and Results-The

Neurally mediated vasodepressor syncope is a common clinical problem. The diagnosis is generally associated with a benign prognosis, however, a less common "malignant" form has been identified. Head-up tilt table testing is helpful in the confirmation of the diagnosis of neurally mediated vasodepressor syncope and may be useful in the selection of therapy. One form of therapy commonly used is beta blockade. In this case report we describe a patient with neurally mediated vasodepressor syncope who developed asystole during head-up tilt table testing after treatment with a beta blocker.
