Objective: Excessive hypertensive response to exercise testing is associated with adverse cardiovascular events such as left ventricular hypertrophy and atrial fibrillation (AF). In this study, we examined the relationship between electromechanical delay and excessive hypertensive response to exercise testing.
Methods: Twenty-five people who had a hypertensive response to the exercise stress test and 28 people who were similar in age and gender with a normal blood pressure response in the exercise stress test as the control group were included in the study.
Results: There was no statistical difference between the study groups in blood pressure holter values, conventional echocardiography findings, and exercise stress test findings. Lateral PA-TDI time (the time from the beginning of the P wave measured by tissue Doppler imaging to the beginning of the A’ wave), left atrial electromechanical delay, and interatrial electromechanical delay were observed to be significantly longer in the hypertensive response group to exercise stress test compared with the control group (74.0±6.3 vs. 68.8±5.7, p=0.003; 24.7±7.0 vs. 19.6±7.1, p=0.013; 36.8±8.5 vs. 30.6±6.6, p=0.003, respectively).
Conclusions: Early detection of electromechanical delay non-invasively may be useful in this patient group in predicting the development of new AF risk.

Amaç: Egzersiz testine aşırı hipertansif yanıtın sol ventrikül hipertrofisi ve atriyal fibrilasyon (AF) gibi istenmeyen kardiyovasküler olaylarla ilişkili olduğu bilinmektedir. Bu çalışmada, elektromekanik gecikmenin egzersiz testine aşırı hipertansif yanıtla ilişkisini inceledik.
Yöntemler: Egzersiz stres testine hipertansif yanıt veren 25 kişi ile egzersiz stres testinde tansiyon yanıtı normal olan yaş ve cinsiyet bakımından benzer 28 kişi kontrol grubu olarak çalışmaya alındı.
Bulgular: Çalışma grupları arasında kan basıncı holter değerleri, konvansiyonel ekokardiyografi bulguları ve egzersiz stres testi bulguları arasında istatistiksel fark yoktu. Lateral PA-TDI süresi (doku Doppler ile ölçülen P dalgasının başlangıcından A’ dalgasının başlangıcına kadar geçen süre), sol atriyal elektromekanik gecikme ve inter-atriyal elektromekanik gecikme, egzersiz stres testine hipertansif yanıt veren grupta kontrol grubuna kıyasla anlamlı olarak daha uzun gözlendi (74,0±6,3 vs. 68,8±5,7, p=0,003; 24,7±7,0 vs. 19,6±7,1, p=0,013; 36,8±8,5 vs. 30,6±6,6, p=0,003, sırasıyla).
Sonuçlar: Elektromekanik gecikmenin non-invaziv olarak erken tespiti, bu hasta grubunda yeni AF riskinin gelişimini öngörmede faydalı olabilir.
