Stabil Koroner Arter Hastalığı Olan Hastalarda Bazal T-Dalgası Pik-Son İntervali ile Kalp Atış Hızı Düzelme İndeksi Arasındaki İlişki

AMAÇ: Koroner arter hastalığı olan hastalarda otonom disfonksiyon kötü prognozun göstergesidir. Bu çalışmanın amacı, sol ventrikül ejeksiyon fraksiyonu (EF)>% 50 ve % 50 olan, 3 damar hastalığı olan 76 hasta vardı. Başlangıçta her iki grubun başlangıç Tp-e ve kalp hızı değerleri ölçüldü ve transtorasik ekokardiyogramlar yapıldı. Daha sonra Grup 1 ve 2, Bruce protokolüne göre egzersiz testine tabi tutuldu ve egzersizin zirvesinde ve 1., 2. ve 3. dakikalarında kalp hızları ölçüldü. BULGULAR: Bazal Tp-e açısından grup 1 [95,8 ± 6,8 msec] ve grup 2 [71,4 ± 5,1 msec] arasında istatistiksel olarak anlamlı fark vardı [P

The Relatioship Between Basal T-Wave Peak-End Interval and Heart Rate Recovery Index Values in Patients with Stable Coronary Artery Disease

OBJECTIVES: Autonomic dysfunction is detected in patients with coronary artery disease and is indicative of poor prognosis. The aim of this study was to compare baseline T peak-end interval (Tp-e) and heart rate recovery index [HRR-I] values in patients with stable coronary artery disease who had a left ventricular ejection fraction [EF] > 50 % and 50 %, had 3-vessel diseases on coronary angiography. Baseline Tp-e and heart rate values of both groups were measured and transthoracic echocardiograms were performed at the beginning. Both Group 1 and 2 were then subjected to exercise testing according to the Bruce protocol and heart rates were measured at the peak and 1st, 2nd, and 3rd minutes of exercise. RESULTS: There was a statistically significant difference between group 1 [95.8 ± 6.8 msec] and group 2 [71.4 ± 5.1 msec] with regard to basal Tp-e [P
