Intermittent chest pain. This series of three ECG were taken from a 41-year-old man with a two-week history of intermittent chest pain. At the time of the first ECG, 12:05 pm, he was pain-free. We see a sinus tachycardia at 102 bpm, and has just come under the care of paramedics. There is a very subtle ST sagging and T wave inversion in Lead III, and no other ST changes. He had an uneventful trip to the hospital.
ST Elevation M.I.
This series of ECGs was taken during ambulance transport of a 67 year old man with chest pain. Earlier the same week, this man had been discharged from the hospital after having a cardiac cath, angioplasty, and stents. He was discharged the next day. The patient stated that, until that hospital admission, he was healthy, athletic, and had no significant medical history. He is currently taking a statin, atenolol, and "one of the new blood thinners" - he didn't know the name.
This 66-year-old man presented with a complaint of chest pain. His ECG shows a "classic" inferior wall ST-elevation M.I. (STEMI). The ST elevation is apparent in Leads II, III, and aVF, which are the leads that reflect the inferior wall of the left ventricle. In addition, this ECG shows ST elevation in Leads V5 and V6, the low lateral wall. The ST depression in V1 and V2 are reciprocal changes caused by acute injury in the posterior wall.
