Transient idiopathic arrhythmias are temporary heart rhythm disturbances without a clear cause, which can be harmless or require treatment if symptoms are frequent. Diagnosis can be challenging, as ...

Reentry arrhythmia occurs when electrical signals in the heart deviate from their usual path, creating a loop that causes repeated stimulation and disrupts the heart’s rhythm. Symptoms of reentry ...

Irregular heartbeats, or arrhythmia, can significantly affect a person’s quality of life and overall health. When medication and lifestyle changes are ineffective, doctors may recommend surgery to ...

Variants in a gene that plays a key role in heart function can cause potentially life-threatening arrhythmia syndromes known as calmodulinopathy. Calmodulinopathy is rare and causes arrhythmias that ...

A study sets the foundation of a ground-breaking treatment regimen for treating ventricular arrhythmia. The research, published in Nature Communications, demonstrates the design and feasibility of a ...

Cardiac arrhythmias are one of cardiology’s major current challenges. They occur when the heart rhythm becomes irregular, too fast, or too slow, affecting both quality of life and survival. An ...

Researchers at Johns Hopkins Medicine built a virtual replica of a patient’s heart, ran electrical simulations through it, and used the results to guide a real ablation procedure for ventricular ...

For the roughly 6 million Americans living with atrial fibrillation, catheter ablation has become an increasingly common treatment, but the procedure still typically keeps patients sedated on a table ...

Cases of atrial arrhythmia in patients with Duchenne muscular dystrophy (DMD) are common but lack a standard solution, and more long-term data on the management of arrhythmias in DMD are needed.

Tachycardia and bradycardia are two types of irregular heart rates. Tachycardia is when the heart beats faster than 100 beats per minute. Bradycardia is when the heart beats slower than 60 beats per ...
