Exercise induced left bundle branch block treated with cardiac rehabilitation: a case report and a review of the literature.

Exercise induced bundle branch block is a rare observation in exercise testing, accounting for 0.5 percent of exercise tests. The best treatment of this condition and its association with coronary disease remain unclear.

The effects of radio-frequency ablation on blood pressure control in patients with atrial fibrillation and hypertension.

Purpose: The effects of radio-frequency ablation (RFA) on blood pressure (BP) regulation in patients with atrial fibrillation (AF) and hypertension remain unknown. We hypothesized that patients with successful ablation had a lower BP and/or lesser utilization of antihypertensive drug therapy during follow-up when compared to patients with failed ablation.

Methods And Results: This was a retrospective evaluation of patients with AF and hypertension treated with ablation at the University of Utah between July 2006 and June 2010.

Management of central venous gradient using excimer laser lead extraction of chronic indwelling pacemaker leads in the setting of ipsilateral arteriovenous fistula.

Device therapy is becoming common in those patients with renal insufficiency. Coexisting need for arteriovenous (AV) fistula placement is often contemplated relative to device placement. We describe the excimer laser lead extraction of a malfunctioning chronic atrial pacemaker lead ipsilateral to an AV fistula.

Implantation of cardiac rhythm devices during concomitant anticoagulation or antiplatelet therapy.

Cardiac rhythm devices are increasingly being utilized as the population ages and the incidence of chronic heart failure, bradyarrhythmias and the indications for pacing and prevention of sudden cardiac arrest expand. The number of patients receiving oral anticoagulants and dual antiplatelet therapy is similarly increasing. Implantation of cardiac rhythm devices during concomitant use of oral anticoagulants or antiplatelet regimens poses an increased risk of perioperative bleeding complications.
