Chest Pain

Not all chest pain is cardiac. Today was chest pain day. A million chest pains came in. Not all chest pain is cardiac.

Other friendly things to consider,

• PE
• Aortic Dissection
• Pneumonia
• Musculoskeletal

I believe from an emergency perspective, probs better to overinvestigate than under. Unless you are willing to put your career on the line.

Lets just review the changes to an ECG during MI.

Initially hyperacute T waves with ST elevation. Within hours to days, there is T wave inversion and development of Q waves.

Pericarditis changes include a saddle shaped ST segment elevation which is diffuse.
