The concept of left atrial systolic time intervals and Doppler echocardiography were used in a quantitative assessment of left atrial function in relation to the presence or absence of a fourth heart sound and to left ventricular hypertrophy in 47 patients with hypertension. Left atrial systolic time interval indexes included atrial pre-ejection period (the time between the onset of an electrocardiographic P wave and the onset of left ventricular inflow during atrial systole [A wave]), corrected atrial pre-ejection period (the atrial pre-ejection period divided by the duration of the P wave), and atrial ejection time (the time between the onset and cessation of the A wave). Twenty-one patients with a fourth heart sound on the phonocardiogram had a shorter atrial pre-ejection period (81 +/- 10 versus 89 +/- 14 ms p less than 0.05) and a corrected atrial pre-ejection period (66 +/- 17 versus 83 +/- 18 ms, p less than 0.01), as well as a longer atrial ejection time (147 +/- 15 versus 126 +/- 13 ms, p less than 0.001) than did 26 patients without a fourth heart sound. The ratio of atrial pre-ejection period to atrial ejection time and that of corrected atrial pre-ejection period to atrial ejection time was smaller in patients with than in patients without a fourth heart sound (0.56 +/- 0.08 versus 0.71 +/- 0.11, p less than 0.001; 0.46 +/- 0.16 ms-1 versus 0.67 +/- 0.17 ms-1, p less than 0.001, respectively).(ABSTRACT TRUNCATED AT 250 WORDS) |
