Association between the physical activity and heart rate corrected‐QT interval in older adults

Abstract

These results suggest that a decreased physical activity level, especially inactivity and light intensity physical activity, were associated with QTc interval in older adults.

Effect of Sub Maximal Dynamic and Static Exercises on QTc interval in Healthy Young Men

“…Our finding is comparable to the findings of other authors [12,19,22,23]. Ogedengbe et al, has showed significant prolongation of QTc in males after quasi dynamic exercise stress test by bicycle ergometer [20].…”

“…The baseline QTc in this age group was found to be 0.36s and was as expected far below the western standards [5,[19][20][21]. The duration of QTc interval is affected by the sympathetic and para sympathetic activity.…”

Association between a frailty index based on common laboratory tests and QTc prolongation in older adults: the Rugao Longevity and Ageing Study

“…These authors proposed that end-stage renal disease patients with more severe frailty exhibit higher levels of fluid accumulation than those with less severe frailty, leading to a shorter QRS duration on their ECGs. 30 In 586 elderly volunteers recruited from a community dwelling, Michishita et al 12 found that decreased physical activity level, especially inactivity and light-intensity physical activity, were associated with prolonged QTc. The authors assumed that the association between reduction in physical activity and a prolonged QTc might be caused by cardiac autonomic nervous system dysfunction and/or electrolyte imbalance, although the outcome of the present study is the intensity of physical activity instead of frailty, and frail patients in the present study may correspond to greater degree of inactivity, which is related to prolonged QTc.…”

“… 10 , 11 In addition, recent data suggest that frailty-related phenotypes are associated with QTc prolongation. Michishita et al 12 reported that inactivity and light-intensity physical activity were associated with QTc in older adults.…”

Intervalo QTc prolongado en pacientes adultos

“…Las alteraciones cardiovasculares son más predominantes en el sexo masculino con el paso de los años, incluso 65 2-3 veces más que en el femenino . El QTc prolongado tiene una relación directa con la escasa actividad física en 68 personas mayores . Los factores mencionados favorecerían una mayor incidencia del sexo masculino.…”
