Intramyocardial Pressure Revisited

  • Chapter
Cardiac Electrophysiology, Circulation, and Transport

Part of the book series: Developments in Cardiovascular Medicine ((DICM,volume 121))

Abstract

It is reasoned that intramyocardial pressure (IMP) and ventricular pressure result from the varying stiffness of the cardiac muscle. This varying elastance concept, well known for the ventricular lumen, should also be applied to interstitial spaces. Since pressure depends on the momentary value of the time-varying elastance and the momentary volume (ventricular lumen and interstitial volume, respectively), ventricular and IMP ventricular pressure are not necessarily related. Therefore, IMP should not be viewed as the result of pressure in the ventricular lumen but as a direct result of cardiac muscle contraction.
