Correlation of mean pulmonary artery wedge pressure, left atrial dimention, and PTF-V1 in patients with acute myocardial infarction.

Pulmonary Artery Wedge Pressure, Left Atrial Dimension, and PTF-V1 in Patients with Acute Myocardial Infarction

pressure or volume overload in patients with valvular heart disease.' Abnormalities in the terminal portion of the P wave in lead V, were also reported in separate studies in patients with pulmonary edema2 and in patients with acute myocardial infarction presenting with clinical and radiographic evidence of congestive heart failure.3 4 These electrocardiographic abnormalities tended to regress ...

Electrocardiographic evidence of left atrial hypertension in acute myocardial infarction.

The relationship between mean left atrial pressure (LAm) and P-wave abnormalities in lead V1 of standard 12-lead electrocardiograms was evaluated in 30 patients with acute myocardial infarction. In each patient pulmonary artery diastolic pressure or pulmonary wedge pressure was measured, and these values were used as an estimate of LAm. Electrocardiograms recorded at the time of the pressure me...

Pulmonary edema related to changes in colloid osmotic and pulmonary artery wedge pressure in patients after acute myocardial infarction.

Pulmonary artery wedge and plasma colloid osmotic pressures and their relationship to pulmonary edema were investigated in 26 patients with acute myocardial infarction of whom 14 developed pulmonary edema. In the absence of pulmonary edema, both the pulmonary artery wedge pressure and plasma colloid osmotic pressure were in normal range; after onset pulmonary edema, a moderate increase in pulmo...

The relationship between pulmonary artery wedge pressure and left atrial pressure in man.

In 17 patients with atrial septal defect, in 12 patients with mitral stenosis and in four patients with unilateral lung tumor but without evidence of mitral valve disease, a similarity in pressure pulse contours in the left atrium and pulmonary artery wedge position was obtained at cardiac catheterization. It is concluded that the pulmonary artery wedge pressure pulse is a reasonably accurate r...
