Immunomodulating therapy with intravenous immunoglobulin in patients with chronic heart failure.

abstract：:An increasing number of premature ventricular stimuli are being used during programmed stimulation of the heart in the investigation of patients with documented or suspected ventricular arrhythmias. To analyze the significance of the different types of ventricular arrhythmias that are initiated, we evaluated in a pros...
