肥大型心筋症 (HCM) の再分極異常の成因を知る目的で, QRST isointegral mapを作成し, 安静時および運動負荷後の分布を検討した.対象は, 正常群10例, HCM群35例 (閉塞型HOCM10例, 非閉塞型HNCM15例, 心尖部型APH10例) である.安静時QRST isointegral mapは, 正常群では左前胸部に極大を, 右胸部上方に極小をもつ分布を示したが, HCMでは , HOCM40%, HNCM60%, APH90%に, 左前胸部に極小をもつ異常分布がみられた.極小点は, APHではV<SUB>4, 5</SUB>周辺に, HNCMではV<SUB>5</SUB>に, HOCMではばらつく傾向があり, 各病型による多少の差異をみとめたが, 重複する例も多くみられた.安静時QRST isointegral mapの異常例に対し, 運動負荷後の分布の変化につき検討した.APHでは9例中8例において, 左前胸部の極小は, 右胸部上方に偏位し, ほぼ正常な分布を示した.HNCMでは9例中8例は, 負荷後も安静時と同様の異常分布を示した.HOCM4例では負荷後左前胸部下方に極小が偏位する傾向がみられた.以上より, HCMの再分極異常は主として1次性変化と考える.また, 運動時変化がHCMの病型で異なったことは, 心筋の肥厚形態の他に, 心筋自体の性質の差による可能性があり, HCMにおける再分極異常の成因は単一のものではないことが示唆される.

The purpose of this study was to evaluate the validity of two different measures of physical activity under normal living conditions. The 24-hour physical activity diary method (24 HD) and accelerometer (Lifecorder) were analyzed. Total daily energy expenditure (TDEE) and daily variation of energy expenditure (EE) were compared employing the two measures in conjunction with the minute-by-minute heart rate method (Flex HR) in middle-aged people with a mean age of 57.9 yr (N=17), and in young people (college students) with a mean age of 23.5 yr (N=11). The TDEE as measured by the 24 HD and Lifecorder was 2576.4±514.7 kcal・d^<-1> and 1973.1±290.2 kcal・d^<-1> respectively. The TDEE as measured by the Flex HR method was 2718.3±625.5 kcal・d^<-1>. The TDEE as measured by the Lifecorder method was significantly lower than that of the Flex HR method (p<0.01). The correlation coefficient (r) for the 24 HD and Flex HR measured values for TDEE (kcal/day) was 0.64 (p<0.01), and that for Lifecorder and Flex HR was 0.38. The daily variation of energy expenditure pattern measured by Lifecorder was similar to that of the Flex HR 24 HD measurements, on the other hand, were slightly lower than Flex HR measurements during the afternoon period. The 24 HD method was reasonably accurate in the testing. The daily variation of energy expenditure measured pattern by Lifecorder was similar to that of the Flex HR method l but the fact that the TDEE results were underestimated suggests that the Lifecorder method has merit in the measurement of daily activity patterns. It follows from this that to improve measurement of the TDEE, it is necessary to modify the Lifecorder method of calculating the algorithm.
