Changes

'''Abnormal rate/rhythm ''': Compromised cardiac output due to an increased or decreased heart rate. Abnormally fast heart rates (tachycardias) result a shorter diastole, therefore impaired filling and reduced stroke volume. Abnormally slow heart rates (bradycardias) limit cardiac output as a direct consequence of reduced heart rate (CO = HR x SV).

'''Diastolic failure ''':  Impaired ventricular filling with normal systolic function. Examples include [[Cardiac Tamponade|cardiac tamponade]] in [[Pericardial Effusion]], [[Pericarditis, Constrictive| Constrictive Pericarditis]] and [[Hypertrophic Cardiomyopathy|Hypertrophic Cardiomyopathy]] or [[Restrictive Cardiomyopathy|Restrictive Cardiomyopathy]]
