Biventricular Pacing: Is Acute Hemodynamic Evaluation Useful to Select Patients?
Acute hemodynamic studies are currently performed to evaluate the effects of drugs or devices on cardiac performance and to understand the mechanisms by which they act. Cardiac pacing has been used to correct bradycardia. However, right ventricular pacing was found to worsen ventricular performance, and new pacing sites capable of preserving ventricular function have been studied. More recently, cardiac pacing has been used to treat congestive heart failure [1–5].
