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 ...

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

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 ...

Elevated resting heart rate is associated with greater risk of cardiovascular disease and mortality. In a 2-stage meta-analysis of genome-wide association studies in up to 181,171 individuals, we ...

Figure 2: Reduction in heart rate during atrial fibrillation after Gα i2 gene transfer. This study is the first report of intracoronary site-specific gene transfer and the first use of gene therapy to ...

New research into human heart development has shed light on the way heart muscle cells contract. A correctly beating heart is vital to a baby's growth during pregnancy, helping guard against heart ...

A new therapy to re-engage the heart's natural electrical pathways - instead of bypassing them - could mean more treatment options for heart failure patients who also suffer from electrical ...

Lucknow: King George's Medical University (KGMU) has introduced ‘Advanced Conduction System Pacing', a new pacemaker method, which helps the heart bea.

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 ...

Peter Spector, M.D.; Nicole Habel, M.D. With H and V-capture there is a combination of these findings. Local V activation is early, QRS onset is early, and QRS end is also early. The QRS duration is ...
