Left Ventricular End-Diastolic Pressure (LVEDP)

A Diagnostic Catheterization & Hemodynamics term on the RCIS exam blueprint, defined for cath lab and EP clinicians.

A key hemodynamic parameter measured during diagnostic catheterization reflecting ventricular preload and diastolic function; critical for diagnosing HFpEF, valvular disease, and other structural pathologies.

Three stacked tracings: a lead II ECG with QRS onset marked, a full-scale left ventricular pressure curve, and a magnified LV diastolic tracing marking the a wave and the Z point at QRS onset where LVEDP is read.
Where to read LVEDP: at the Z point, after the atrial contribution and before pressure rises.
