Even indoor walking is good for cardiovascular health, and it can be a “safer” exercise option for many people, especially as summer sets in and heat safety is a concern. As a doctor born and ...
The RCA also supplies the SA nodal artery in 60% of people. The other 40% of the time, the SA nodal artery is supplied by the left circumflex artery. [citation needed] Although rare, several anomalous courses of the right coronary artery have been described including origin from the left aortic sinus. [9]
