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.

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.

We sought to determine predictors of RV pacing in patients who did not have a pacing indication at the time of initial ICD implant. Conclusions This study provides insight into predictors of RV pacing in ICD recipients without pacing needs at baseline.

She was unable to be defibrillated but was cannulated and placed on ECMO in our Emergency Department (ECLS - extracorporeal life support). After good ECMO flow was established, she was successfully defibrillated. Here is a case of ECMO defibrillation with near shark fin that was due to proximal LAD occlusion. The K was normal.

She was defibrillated and resuscitated. It is apparently fortunate that she had a cardiac arrest; otherwise, her ECG would have been ignored. In a recent article (J Electrocardiol this year, see reference below), peak trop onin I levels in takotsubo presenting with ST Elevation were median 1.02 ng/mL [IQR: 0.46, 2.35].

Using automated external defibrillators (AEDs) and cardiopulmonary resuscitation (CPR) as soon as possible increases a person's chance of surviving a cardiac arrest. After meeting the exclusion criteria, more than 9,500 cases of out-of-hospital cardiac arrest were included in the study cohort. versus 4.6%

At cath, he immediately had incessant Torsades de Pointes requiring defibrillation 7 times and requiring placement of a transvenous pacer for overdrive pacing at a rate of 80.

He required multiple defibrillations within a period of a few hours. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. Some episodes of PMVT would terminate spontaneously — but on many occasions, the PMVT degenerated to VFib, requiring defibrillation.

We rapidly defibrillated her, and with return of normal sinus rhythm. Several minutes later the patient developed V-fib again > 200J defibrillation with return to NSR. Rapid sequence intubation was performed for airway protection in setting of recurrent V-fib and defibrillations. Chest X-ray also showed pulmonary edema.
