Population
Palpitation patients and normal subjects
Comparison
Spectral harmonic energy ratio analysis of the… vs Normal subjects

Key result
The mean spectral harmonic energy ratio (SHER) of the arterial pulse was significantly higher in palpitation patients compared to normal subjects (57.7 vs 39.7; P=0.0066).

SHER elevation may signal vascular changes in palpitations; leaves open diagnostic utility pending validation.

Does the spectral harmonic energy ratio (SHER) differ between palpitation patients and normal subjects?
Absolute Event Rate: 57.7% vs 39.7%
p-value: p=0.0066
The spectral harmonic energy ratio (SHER) can effectively distinguish palpitation patients from normal subjects by quantifying the abrupt decrease in higher-order harmonics of the arterial pulse.
Huang et al. (2010) conducted an observational in Palpitations. Palpitations vs. Normal subjects was evaluated on Spectral harmonic energy ratio (SHER) (p=0.0066). The mean spectral harmonic energy ratio (SHER) of the arterial pulse was significantly higher in palpitation patients compared to normal subjects (57.7 vs 39.7; P=0.0066).
