“…The higher rates of arrhythmias especially atrial fibrillation in women may be related to the higher frequency of valvular heart disease [23,24]. Hypertension and ischemic heart disease which are diagnosed more frequently in men may explain the higher burden of LVH and ST-T abnormalities in them [25][26][27][28].…”

“…Some patients decompensate acutely with increasing LV dilatation and decreasing ejection fraction, particularly with added stress from infection or noncardiac illness. The radius (r) increases and the wall thickness (h) decreases, thereby increasing wall stress, sometimes markedly . It is possible to calculate the increase in wall stress and use this as a multiplier for oxygen consumption.…”

“…Voltage and repolarization abnormalities have been identifi ed as markers of depressed left ventricular EF [1][2][3], and previous work has revealed that signs of a left ventricular conduction delay, i.e. R peak time prolongation in the left-sided leads or R peak delay (maximum R peak time in I, V5 or V6 exceeding the S peak time of the maximum S in V1, V2 or V3), assist in the assessment of systolic dysfunction in chronic AR [4].…”

The study was conducted to ascertain that the ECG assists in the assessment of systolic dysfunction in chronic aortic regurgitation. Five variables were reviewed in 146 adults without bundle branch block who underwent angiocardiography: total 12-lead QRS amplitude, QRS duration, maximum R peak time in I, V5 or V6, maximum R peak time relative to S peak time of the maximum S in V1, V2 or V3, and maximum T wave amplitude and polarity in I, V6 or aVF. In order to define which of them could differentiate left ventricular ejection fraction (EF) ≥50% (n = 101) from EF <50% (n = 45) they were subjected to stepwise linear discriminant analysis. The maximum R peak time relative to S peak time emerged as the most promising variable. In predicting EF <50%, R peak time prolongation exceeding S peak time, i.e. R peak delay, yields reliable results, with specificity, positive and negative predictive value being 89.1%, 70.3% and 82.6%, respectively, and sensitivity being 57.8%. As given by the sample odds-ratio, R peak delay indicates an 11-fold increased risk of having EF <50%. R peak delay, a marker of left ventricular function-conduction impairment identifies patients who need valve replacement.
