Scientists studying genetic data from nearly 50,000 people have uncovered several DNA sequence variations associated with the electrical impulses that make the heart beat. The findings may pave the ...

The European Society of Cardiology (ESC) has released a groundbreaking consensus statement on conduction system pacing (CSP), marking a significant milestone in the evolution of pacing therapy. The ...

Electrocardiogram (ECG) measures taken after the first pig-to-human heart transplant found significantly different electrical conduction characteristics compared to those seen in native pig hearts ...

New research highlights postnatal regeneration limits and pathological remodeling of the cardiac conduction system after myocardial infarction, uncovering mechanisms behind clinical arrhythmogenesis ...

Figure 1: Measurement of gene transfer efficacy. Figure 2: Reduction in heart rate during atrial fibrillation after Gα i2 gene transfer. This study is the first report of intracoronary site-specific ...

You are reviewing an ECG you arranged for a 56-year-old man with newly diagnosed hypertension. The trace is normal but the computerised report notes ‘first-degree heart block’. Looking at the ...

This is a narrow complex tachycardia with a rate of 124 beats/min. The QRS morphology and axis are normal. The QTc is prolonged, at 529 ms (normal, 390-450 ms for men). The underlying P waves appear ...

But slow conduction of action potentials that can lead to heart arrhythmias depends on calcium channels, which, in turn, are modulated by cell calcium. "CaMKII mediates an important regulatory pathway ...

These days having both a land line and a mobile phone seems like overkill. But Virginia Tech researchers have shown that the heart relies on at least two key communication channels to keep abnormal ...
