PO-03-014 DEEP LEARNING ON THE ELECTROCARDIOGRAM TO PREDICT CARDIOMYOPATHY IN PATIENTS UNDERGOING NON-CONDUCTION SYSTEM PACING

HeartRhythm

In patients undergoing non-physiologic pacemaker (PM) implantation (eg, RV pacing), cardiomyopathy (CM) may develop - particularly in patients with an elevated pacing burden. In contrast to the current standard of upgrading the pacemaker only once CM develops, a strategy to predict CM before it actually develops would be advantageous.

Pacing on the tail of paced QRS: What is the mechanism?

HeartRhythm

An electrocardiogram on the day following the implantation of a dual-chamber pacemaker revealed two closely coupled pacing spikes at 100ms intervals with the latter being on the trailing edge of the paced QRS complex. The critical analysis of the pacemaker timing intervals led to the mechanism and aetiology of the problem.

Case Report: A case of third-degree atrioventricular block associated with primary cardiac lymphoma

Frontiers in Cardiovascular Medicine

The initial electrocardiogram revealed a third-degree atrioventricular block. After surgical resection of the tumor and implantation of a permanent pacemaker, the symptoms of the patient were significantly improved, allowing subsequent chemotherapy.

Cardiomatics guide: Analyzing arrhythmias made easy

Cardiomatics

In a world where technology reigns supreme, one of the most profound tools in medicine remains the irreplaceable electrocardiogram (ECG). ECG waveform Cardiomatics catalog of ECG events: Sinus rhythm – the normal heart rhythm is the sinus rhythm generated by the physiological pacemaker, the sinus node.

Case Report: Complete atrioventricular block in an elderly patient with acute pulmonary embolism

Frontiers in Cardiovascular Medicine

Case presentation Here, we present the case of a 91-year-old woman with acute pulmonary embolism, whose initial electrocardiogram showed a complete atrioventricular block. Catheter-directed thrombolysis and a temporary pacemaker insertion were carried out sequentially. Echocardiography confirmed signs of right ventricular dysfunction.

An unruly case of functional two-to-one atrioventricular block

HeartRhythm

A newborn male was delivered via cesarean section at term due to acute fetal distress and fetal bradycardia, necessitating emergency pacemaker implantation. An electrocardiogram (ECG) showed a two-to-one atrioventricular (AV) block and a prolonged QT interval, along with biphasic T-waves in V3 (Figure 1A).

Physical Examination as a Helpful Aid in Decision-Making in Challenging ECGs

Dr. Smith's ECG Blog

An initial electrocardiogram (ECG) is provided below. Again, see Ken's discussion below) Discussion continued The absence of pace spikes suggests this is not a pacemaker/ICD-related rhythm in this patient with an ICD. The patient was promptly admitted to the hospital for further evaluation. What do you think? What is the rhythm?
