Cardiologists Train Large AI Model to Assess Heart Structure, Function

DAIC

Cedars-Sinai and Smidt Heart Institute investigators developed a novel foundation model that integrates computer vision interpretation of echocardiogram images with natural language processing to augment cardiologists’ interpretation of echocardiograms. Image by Getty.

Completely Wireless: First Concomitant Dual Chamber Leadless Pacemaker and Subcutaneous Defibrillator Implant

HeartRhythm

An 80-year-old man with renal disease on hemodialysis, coronary artery disease, complete heart block and a dual chamber leadless pacemaker (LP) implanted because of previous bacteremia, presented with syncope. An echocardiogram showed newly reduced left ventricular ejection fraction of 30-35%.

Different leadless pacemakers working in harmony (Aveir in the atrium/Micra AV2 in the ventricle) in a patient with dextrocardia and double outlet right ventricle after high?risk infected device extraction

Journal of Cardiovascular Electrophysiology

Due to atrial and ventricular pacing dependence, a comprehensive congenital care team concluded the need for lead extraction and replacement of pacemaker via leadless peacemaking device. Laser-lead extraction and temporary atrial pacemaker placement was performed.

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

Dr. Smith's ECG Blog

Place temporary pacemaker 3. EKG with paced complexes shown below shows much narrower QRS complex and echocardiogram showed improved LV systolic function primarily due to improvement in LV dyssynchrony. (J Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses.

Correlation of ventricular pacing burden and left ventricular function in patients with heart failure with reduced ejection fraction

Journal of Cardiovascular Electrophysiology

Impact of preceding systolic heart failure on risk of pacemaker-induced cardiomyopathy Abstract Background Pacemaker-induced cardiomyopathy is a well described phenomenon in patients with preserved ejection fraction at the time of permanent pacemaker implant.

A woman in her 50s with multiple episodes of syncope

Dr. Smith's ECG Blog

They knew she would need a pacemaker unless some transient and reversible cause was discovered. Once this happens, of course, the patient will require temporary or permanent pacemaker as soon as possible. She required intermittent pacing from the temp wire numerous times overnight so a permanent pacemaker was placed the next day.

Effect of Paced Heart Rate on Quality of Life and Natriuretic Peptides for Stage B or C HFpEF: A Secondary Analysis of the myPACE Trial

European Journal of Heart Failure

This study aimed to evaluate the impact of higher backup pacing rates in HFpEF patients with preexisting pacemaker systems that limit pacemaker-mediated dyssynchrony across left ventricular (LV) volumes and ejection fraction (LVEF). No evidence of heterogeneity was found across LV volumes or LVEF for pacemaker-detected AF burden.
