Functional Consequences of Atrial Fibrillation
Back
Tachycardia
Rapid rate -> decreased filling time -> decreased end diastolic volume (EDV)
Shortened diastole -> interference with coronary perfusion
Decreased ventricular filling
Disorganized atrial systole -> loss of atrial kick (~15% EDV)
Results in decreased stroke volume (SV) -> decreased cardiac output (CO)
Thromboembolic events
Disorganized atrial systole -> atrial blood stasis -> thrombus
