Page "Heart failure" Paragraph 34

Additional signs indicating left ventricular failure include a laterally displaced apex beat ( which occurs if the heart is enlarged ) and a gallop rhythm ( additional heart sounds ) may be heard as a marker of increased blood flow, or increased intra-cardiac pressure.

Heart murmurs may indicate the presence of valvular heart disease, either as a cause ( e. g. aortic stenosis ) or as a result ( e. g., mitral regurgitation ) of the heart failure.
