Objective
Asymptomatic atrial fibrillation episodes detected by pacemaker is known to increase the risk of systemic embolism and stroke by 2-3 times in patients with dual-chamber pacemaker. Atrial high-rate episodes presence together with duration of episodes is also an important indicator of adverse events. The studies have shown the relationship between the electrocardiographic diastolic index and the development of diastolic dysfunction. The aim of our study was to show the relationship between the ECG index (Tend-P/[PQxAge]) and atrial fibrillation in patients with dual-chamber pacemaker.
Materials-Methods
The 49 patients with dual-chamber pacemaker were included in the study. These patients were divided into two groups according to the presence of atrial high-rate episodes lasting 5 min or more. Atrial high-rate episodes detected in 24 patients were identified as Group-1, was not detected in 25 patients as Group-2.Their demographic, electrocardiographic and echocardiographic data has evaluated. Relationship between these data and the occurrence and duration of atrial high-rate episode has evaluated.
