Again, it is common to have an ECG that shows apparent subendocardial ischemia after resuscitation from cardiac arrest, after defibrillation, and after cardioversion. and repeat the ECG, to see if the apparent ischemia persists. An echocardiogram showed: Left ventricular hypertrophy concentric. This was done. Smith SW.

It should be kept in mind that on occasions, beta-one agonist can result in increased ventricular ectopy e.g., in severe myocardial ischemia (by increasing myocardial demand), or sometimes with congenital long-QT syndrome. Smith, this can be accomplished by either using beta-one agonists or temporary transvenous pacing. J Am Coll Cardiol.

This may result in ischemia (lack of oxygen to the heart muscle), causing parts of the heart to weaken and enlarge. Echocardiogram An echocardiogram uses sound waves to produce a detailed image of the heart, allowing doctors to see the size of the heart chambers and how well the heart is pumping blood.

He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine. ACS would be highly unusual in a young athlete, and given the information on his race bib, one must first suspect that the abnormal ST elevation is due to demand ischemia, not ACS. This young male had ventricular fibrillation during a triathlon.

He underwent further standard resuscitation EXCEPT that we applied the Inspiratory Threshold Device ( ResQPod ) AND applied Dual Sequential Defibrillation (this simply means we applied 2 sets of pads, had 2 defib machines, and defibrillated with both with only a fraction of one second separating each defibrillation.

She was found to be in ventricular fibrillation and was defibrillated 8 times without a single, even transient, conversion out of fibrillation. She was immediately intubated during continued compressions, then underwent a 9th defibrillation, which resulted in an organized rhythm at 42 minutes after initial arrest. see below).

The patient has also developed sinus bradycardia, which may result from right coronary artery ischemia to the SA node. During angiogram in the cath lab, the patient suffered two episodes of ventricular fibrillation for which he was successfully defibrillated. Two stents were placed with resultant TIMI 3 flow.
