Aims To assess the effect of experimentally induced atrial fibrillation on coronary flow in
humans. Methods and Results In 16 patients (10 men, mean age 43±13 years) with normal …

Background Different mechanisms have been proposed to relate atrial fibrillation (AF) and
coronary flow impairment, even in absence of relevant coronary artery disease (CAD) …

Objectives: The purpose of this study was to assess atrial myocardial perfusion in patients
with lone recurrent atrial fibrillation (LRAF). Background: Although acute atrial ischemia has …

To assess the effects of pacing-induced tachycardia on phasic coronary blood flow pattern
and flow reserve of left anterior descending artery, we examined 16 patients with chest pain …

Objective: We tested the hypothesis that beat-to-beat changes in haemodynamics during
atrial fibrillation include an effect of each preceding R–R interval through the interval …

Beat-to-beat variation in blood flow dynamics during atrial fibrillation (AF) has been
associated with evidence of endothelial dysfunction. The aim of the present work is to …

The direct determinants of coronary flow are lumen area and blood flow velocity; however,
the precise mechanisms that control these factors are not fully understood. The aim of the …

Background Atrial fibrillation (AF) is associated with myocardial infarction, and patients with
AF and no obstructive coronary artery disease can present with symptoms and evidence of …

Impaired coronary flow reserve immediately after coronary angioplasty may be attributed to
an increase in resting coronary blood flow. To test this hypothesis we measured great …

Measurement of coronary flow velocity in clinical cases contributes to understanding the
pathophysiology of coronary circulation. To determine absolute coronary flow velocity …
