Edited by Bracey, Meyers, Grauer, and Smith A 50-something-year-old female with a history of an unknown personality disorder and alcohol use disorder arrived via EMS following cardiac arrest with return of spontaneous circulation. T wave alternans is a harbinger of cardiac instability and TdP. (3) No ischemic ST changes.

Here was his initial ED ECG: There is sinus tachycardia at a rate of about 140 There is profound ST Elevation across all precordial leads, as well as I and aVL. If a patient presents with chest pain and a normal heart rate, or with shockable cardiac arrest, then ischemic appearing ST elevation is STEMI until proven otherwise.

A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. Cardiac arrest Cardiac arrest is a medical emergency in which the heart stops pumping blood to the body. Electrocardiogram, echocardiogram, and some other tests are done for patients with cardiac arrest.

Video-based AI A profound learning approach is created with a video-based neural system that utilizes a current database of video formats to determine cardiac issues. The deep learning algorithm helps segment the left ventricle predicting cardiomyopathy and ejection fraction. AI recognizing cardiac arrests in emergency calls.

Here is his 12-lead: There is a wide complex tachycardia with a rate of 257, with RBBB and LPFB (right axis deviation) morphology.

Other than tachycardia, Other than slight tachycardia, vitals were within normal limits (including oxygen saturation). As always, takotsubo cardiomyopathy and focal pericarditis can mimic OMI, but takotsubo almost never mimics posterior MI, and both are diagnoses of exclusion after a negative cath. The PR interval is normal.

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.

NOTE: As discussed in detail in ECG Blog #108 — " A IVR" is an "enhanced" ventricular ectopic rhythm that occurs faster than the intrinsic ventricular escape rate ( which is typically between 20-40/minute ) — but slower than hemodynamically significant Ventricular Tachycardia ( ie, VT at rates >130-140/minute ).
