The analysis of heart rate variability (HRV) and heart rate (HR) dynamics by Holter ECG has been standardized to 24 hs, but longer-term continuous ECG monitoring has become available in clinical practice. We investigated the effects of long-term ECG on the assessment of HRV and HR dynamics.

通过 7 天连续心电图监测增强对心率变异性和动态异常的检测

动态心电图对心率变异性 (HRV) 和心率 (HR) 动态的分析已标准化为 24 小时，但更长期的连续心电图监测已在临床实践中可用。我们调查了长期心电图对 HRV 和 HR 动态评估的影响。
