抄録

Heart rate variability of Holter electrocardiogram (ECG) that incidentally recorded the onset process of heatstroke during golf play was analyzed in comparison to control ECGs in the same subject. During playing golf normally, the amplitude of high-frequency component (HFA), known as an index of cardiac parasympathetic function, was suppressed (4.3 ± 2.2 ms). Whereas, 135 min before the onset of syncope, spiky HF bursts (amplitude ~10 ms and width <60 s) appeared at an interval of 10-15 min and the burst amplitude increased to 20-30 ms 50 min before the onset. No such phenomenon was observed in control ECGs even during walking exercise. Spiky HF burst may be used as a prodromal sign for predicting heatstroke from heartbeat information.
