The patient with no prior cardiac history presented in the middle of the night with acute chest pain, and had this ECG recorded during active pain: I did not see any ischemia on this electrocardiogram. Their apparently excessive length (QT interval) is due to bradycardia. They do not have much bulk.

An electrocardiogram is a machine used to record the heart's electrical activity. A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. Electrocardiogram, echocardiogram, and some other tests are done for patients with cardiac arrest. ECG and EKG refer to the same thing.

Here are inferior leads, and aVL, magnified: A closer inspection of the inferior leads and aVL Sinus bradycardia. I had no history on the case and no prior ECG for comparison. What do you think? The T-wave in lead III is slightly tall and broad (increased area under the curve) compared to its QRS complex.

Abnormal Electrocardiogram (ECG): Defined (San Fran syncope rule) as any new changes when compared to the last ECG or presence of non-sinus rhythm. Evidence of acute ischemia (may be subtle) vii. Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
