The localisation of the occlusion can be adequately visualized using
a coronary angiogram (CAG).
21. Posterior Leads
• Posterior leadsV1,V2
• Posterior Infarct with ST
Depressions and/ tall R wave
• RCA and/or LCXArtery
ST elevation inV7,V8,V9.
• Understand Reciprocal changes
• The posterior aspect of the heart is
viewed as a mirror image and therefore
depressions versus elevations indicate
MI
• Rarely by itself usually in combo.

25. ECG 1.The ECG above belongs to a patient with stable angina pectoris.The patient complained of effort angina
in the last 2
weeks. Coronary angiography was performed and then the patient was referred to coronary artery bypass graft
operation
because of 3 vessel disease. ST segment flattening is one of the first signs of coronary ischemia and generally
preceedes ST
segment depression.
