Left ventricular pressure-volume relationship in conscious mice.
With the availability of transgenic models, the mouse has become an increasingly important subject for genetic-hemodynamic studies. Recently, we developed a technique to measure left ventricular (LV) pressure in conscious mice with an implanted LV polyethylene tube. We extended our new method by evaluating the LV pressure-volume relationship and examined the feasibility of this method in this s...
متن کاملLeft Ventricular Pressure-Volume Alterations
Left ventricular function, pressure-volume relationships, and wall motion were studied by sequential cineventriculography during acute myocardial ischemia, induced by atrial pacing, in 10 subjects. Observations made in this group were contrasted to data obtained during atnal pacing in a smaller normal group. An acute alteration in the pressure-volume relation occurred in five subjects during is...
متن کاملLeft Ventricular Pressure-Volume Relationships
It has been shown in man that myocardial ischemia, whether precipitated by exercise or pacinginduced tachycardia, is associated with abnormalities of left ventricular end-diastolic pressure. There has been controversy as to whether this relationship is due to decreased myocardial compliance or to an increase in left ventricular volume as a manifestation of left ventricular failure. Simultaneous...

متن کاملThe effect of right ventricular filling on the pressure-volume relationship of ejecting canine left ventricle.
Acute shifts in the pressure-volume relationship of the left ventricle occur under several conditions. One potential mechanism for this phenomenon is ventricular interdependence, that is, the influence of right ventricular filling on the left ventricle. This mechanism was studied in an isolated cross-circulated ejecting canine heart preparation with balloons sewn into both right and left ventri...
