This can initiate ventricular arrhythmias like polymorphic ventricular tachycardia (PMVT). She was externally defibrillated with 200J and received magnesium and an IV amiodarone bolus. She was successfully defibrillated with 360J. Telemetry showed Spike-on-T phenomenon which initiated PMVT.

She was successfully revived after several rounds of ACLS including defibrillation and amiodarone. T wave alternans is characterized by variation in T-wave morphology in the setting of consistent pacemaker and QRS morphology. (1) T-wave alternans and the susceptibility to ventricular arrhythmias.

Arrhythmias : A leadless pacemaker-defibrillator system provides antitachycardia pacing for ventricular tachycardia in patients with subcutaneous ICDs. Coronary Heart Disease : Initiate beta-blockers in patients with acute MI and normal LVEF unless contraindicated or if they have heart failure.

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. 25, 2022 ).

Implantable Devices Implantable cardiac devices, such as pacemakers and implantable cardioverter-defibrillators (ICDs), are crucial in managing arrhythmias and other cardiac conditions. GEMMSOne’s robust analytics capabilities further support data-driven decision-making, optimizing heart disease management and outcomes.

She was never defibrillated. Therefore, she underwent temporary pacemaker placement and overdrive pacing at a rate of 90 bpm to keep the heart rate up in order to prevent these PVCs triggering ventricular arrhythmia. Hypokalemia was unlikely because she continued to have ventricular arrhythmia despite of correcting electrolytes.

However, he suddenly developed a series of malignant ventricular arrhythmias. He required multiple defibrillations within a period of a few hours. Below are printouts of some of the arrhythmias recorded. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation.

Isoprenalin was discontinued, and a temporary transveous pacemaker was implanted. The patient stabilized following pacemaker placement. She was given CRT-D (Cardiac Resynchronization Therapy-Defibrillator). VT is the second most common presenting arrhythmia. The above ECG initially shows AV block.

Subcutaneous implantable cardioverter defibrillator was an innovation meant to reduce the lead related problems of conventional transvenous ICDs. To circumvent this problem, a modular communicative leadless pacing–defibrillator system has been devised and a study published in the New England Journal of Medicine [1]. N Engl J Med.

More than 1 million permanent pacemakers are implanted worldwide each year, half of which are in patients with high-grade atrioventricular block. Pacemakers provide adequate frequency support in the initial stage, but traditional right ventricular (RV) pacing may lead to or aggravate left ventricular dysfunction and arrhythmia.

How does a pacemaker accomplish RBBB morphology? This is the shock coil and identifies this device as a defibrillator. Quick aside on device terminology (feel free to skip): A "single chamber" pacemaker is a device with only one lead. A "dual chamber" pacemaker is a device with an atrial lead and a ventricular lead.
