Having an accelerated junctional rhythm occurs when the atrioventricular node in your heart beats too quickly. It happens as a result of damage to your heart’s primary natural pacemaker. There’s no ...

From competency checklists to wearable tech breakthroughs, ECG training and monitoring are evolving to meet learners’ and clinicians’ needs. Whether you’re mastering lead placement or exploring ...

A fundamental discovery reported in the March 1 issue of the journal Nature uncovers the first molecular evidence linking the body’s natural circadian rhythms to sudden cardiac death (SCD).

The sinoatrial (SA) node is the natural pacemaker of the heart. It generates electrical impulses that cause the heart’s chambers to contract, setting the heart rate. The SA node typically generates 60 ...
