This is an angiogram of a non-dominant right coronary artery in a patient with a dominant left circumflex artery. The RCA is very small, compared to the usual. This patient is one of about 15 - 18% of the population whose circumflex artery perfuses the posterior/nferior wall of the left ventricle.

This is an angiogram of a left coronary artery (LCA). The circumflex artery, labelled CX, is dominant, meaning that it connects to the posterior descending artery and perfuses the posterior and inferior walls of the left ventricle. Approximately 15-18% of the population has a dominant circumflex artery. In about 80-85% of people, the right coronary artery (RCA), perfuses the inferior wall.

A very simple illustration showing the PR interval and the QRS duration, along with a closeup of the ECG graph paper.
This image is taken from the patient featured in our Teaching Series, AWMI. This shot shows the left anterior descending artery just after a stent has been placed and blood flow returned. There had been a 100% occlusion prior to the angioplasty. The circumflex and obtuse marginal arteries show evidence of severe coronary artery disease and multiple partial obstructions, and were also repaired.
