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

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

	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

EDV: end-diastolic volume, ESV: end-systolic volume, EF: ejection fraction, HR: heart rate,
*** p < 0,0001 vs. end-diastolic, end-systolic volume and *p < 0.05 vs. ejection fraction by single beat.
