Table 2 Mean ± SD values for left ventricular end-diastolic volume (ml), end-systolic volume (ml) and ejection fraction (%) for the different imaging strategies

From: Three-dimensional echocardiography using single-heartbeat modality decreases variability in measuring left ventricular volumes and function in comparison to four-beat technique in atrial fibrillation

  EDV (ml) ESV (ml) EF (%) HR (bpm)
Group A
Four-beat full volume 102 ± 25 47 ± 19 54 ± 10 67 ± 10
Single-beat full volume 99 ± 25 47 ± 20 53 ± 10 67 ± 11
Group B
Four-beat full volume 87 ± 27*** 52 ± 22*** 41 ± 11* 97 ± 27
Single-beat full volume 119 ± 34 64 ± 27 47 ± 12 97 ± 26
  1. EDV: end-diastolic volume, ESV: end-systolic volume, EF: ejection fraction, HR: heart rate,
  2. *** p < 0,0001 vs. end-diastolic, end-systolic volume and *p < 0.05 vs. ejection fraction by single beat.
