Abstract:
BACKGROUND: Reduced heart rate varaibility (HRV) after acute myocardial infarction (AMI) is an important risk factor for mortality and life-threatening arrhythmias. The correlation between the left ventricular (LV) diastolic function and autonomic balance expressed by HRV in patients with AMI was evaluated in this study. METHODS: A 2-dimensional and Doppler echocardiography and a 24-hour Holter monitoring were performed at 5th to 7th day after attack in 50 patients with AMI. The restrictive filling pattern of the LV diastolic function was defined by E/A ratio >2 or deceleration time (DT) of the mitral inflow
