Bradycardia Defibrillator Heart Failure

Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. Because she has cardiomyopathy and ventricular dysrhythmias, the pacer included an Implanted Cardioverter-Defibrillator (ICD) Echo 6 days later after CRT: Normal estimated left ventricular ejection fraction. The plan: 1.

During the night, while on telemetry, the patient became bradycardic, with periods of isorhythmic AV dissociation (nodal escape rhythm alternating with sinus bradycardia), and there were sporadic PVCs. She spontaneously converted (Defibrillation was not performed). NT-pro-BNP peaked at 4831, consistent with heart failure.

He denied any known medical history, specifically: coronary artery disease, hypertension, dyslipidemia, diabetes, heart failure, myocardial infarction, or any prior PCI/stent. Despite immediate chest compressions, and multiple rounds of defibrillation, he could not be resuscitated. Breath sounds were clear in all lung fields.

We examined the effect of ibutilide, a class III antiarrhythmic agent, on the energy requirement for atrial defibrillation and assessed the value of this agent in facilitating cardioversion in patients with atrial fibrillation that is resistant to conventional transthoracic cardioversion.

The following are key points to remember from a review article on cardiac implantable electronic devices (CIEDs), which include pacemakers for bradycardia, biventricular pacemakers for heart failure, and implantable cardioverter–defibrillators (ICDs) for the treatment of sudden cardiac death:

Here is the transcript of the video: Implantable defibrillator is an important life saving device. Then, why is it mentioned that, implanting a defibrillator soon after an acute myocardial infarction, in those with left ventricular dysfunction and prone for ventricular arrhythmias and sudden cardiac death, is not useful?

The arrhythmia spontaneously converted before defibrillation was achieved. The patient spent a couple of days in the cardiac intensive care unit receiving treatment for acute heart failure and aspiration pneumonia. How did the Queen of Hearts do on today's ECGs? Long term follow up is not available.
