title: Interpretation of cardiac pathophysiology from pressure waveform analysis: pacemaker hemodynamics.
abstract: The abnormal sequence of A-V contraction produces alteration of right and left heart hemodynamics reflecting the inappropriate timing of atrial contraction to ventricular filling. Some symptomatic patients may require A-V sequential pacing to improve cardiac output. The clinical effects of the atrial contribution to left ventricular function can be demonstrated by careful review of hemodynamic tracings in these individuals.
