Interventricular Septum Membranous Portion

Question 13

Ablation site for atrial flutter

Answer 13

cavotricuspid isthmus, a narrow area of tissue below the coronary sinus opening, between the tricuspid valve and the inferior vena cava.

Question 17

Right coronary artery supplies which structures

Answer 17

right side of heart
SA node

Question 18

Left Coronary artery divides into which?

Answer 18

Left Anterior Descending (2/3 interventricular septum, anteopapillary muscle, antero left ventrciel)

Left Circumflex
Posteriorlateral LA, LV, anterolateral papillary muscle

Question 23

Most people are ____ dominant?

Answer 23

Right sided dominant (85%)

Question 24

Right coronary artery is at higher risk for arrthymias- why?
