PROBLEM TO BE SOLVED: To provide an electrocardiogram analysis device capable of calculating an index independent of the magnitude of an R wave, which is usable as a new diagnostic reference of left ventricular hypertrophy based on an electrocardiogram signal.SOLUTION: With respect to the interval from the end point of an S wave to the end point of a T wave of an electrocardiogram signal reflecting the electrical activity of a left ventricular sidewall, an index based on the sum of the values of electrocardiogram signals based on the level of a predetermined baseline is calculated as an index relating to left ventricular hypertrophy.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】心電図信号に基づく左室肥大の新たな診断基準として利用可能な、R波の大きさに依存しない指標を算出可能な心電図解析装置を提供すること。【解決手段】左室側壁の電気的活動を反映する心電図信号のS波の終了点からT波の終了点までの区間について、予め定められた基線のレベルを基準とした心電図信号の値の和に基づく指標を、左室肥大に関する指標として算出する。【選択図】図2
