Heart failure is caused by chronic oxygen deprivation due to reduced blood flow, which weakens the heart over time.

The coronary arteries can constrict as a response to various stimuli, mostly chemical. This is known as a coronary ...
A Wiggers diagram modified from [1]. A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century.
Firstly, more muscle mass will result in greater amplitude of depolarisation of that side of the heart. [15] Secondly, depolarisation of the heart will be slower through the right ventricle relative to the left, and therefore the effects of the right ventricle on the axis of the heart will be dominant.
