Leadless Pacing Wirelessly Linked to Subcutaneous Defibrillator Hits Targets for ATP

Med Page Today

(MedPage Today) -- BOSTON -- A leadless pacemaker reliably communicated with a subcutaneous implantable cardioverter-defibrillator (S-ICD) to deliver anti-tachycardia (ATP) and bradycardia pacing, the MODULAR ATP study showed. In terms of safety.

A Modular Communicative Leadless Pacing–Defibrillator System

American College of Cardiology

Is a novel modular pacing–defibrillator system, consisting of a leadless pacemaker in wireless communication with a subcutaneous implantable cardioverter–defibrillator (ICD), able to effectively and safely provide antitachycardia and bradycardia pacing?

Review on Cardiac Implantable Electronic Devices: Key Points

American College of Cardiology

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:

Torsade in a patient with left bundle branch block: is there a long QT? (And: Left Bundle Pacing).

Dr. Smith's ECG Blog

Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. Place temporary pacemaker 3. There is ventricular bigeminy with bizarre appearing wide T-waves See even more striking cases of this at the bottom of the post. The plan: 1. No wall motion abnormality.

Transcutaneous Pacing: Part I

EMS 12-Lead

This is demonstrated ( Figure 5 ) by the gap in arrows at the bottom of the strip, signifying that the demand pacemaker has recognized an underlying rhythm (in this case, artifact from a moving ambulance). The artifact fools the pacemaker into thinking the rhythm is native.

What are treatment options for this rhythm, when all else fails?

Dr. Smith's ECG Blog

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.

What kind of AV block is this? And why does she develop Ventricular Tachycardia?

Dr. Smith's ECG Blog

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). The above ECG initially shows AV block. A run of very fast, irregular polymorphic VT ensues.
