Investigators found that an artificial intelligence (AI) algorithm can detect an abnormal heart rhythm in people not yet showing symptoms. The algorithm, which identified hidden signals in common ...

Steven Poelzing (left) and Gregory Hoeker, researchers at the Fralin Biomedical Research Institute at VTC, collaborated on a new study published in the journal Heart Rhythm revealing why low blood ...

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).

Use of an Apple Watch for heart rhythm monitoring was feasible and picked up more arrhythmias than a standard patch monitor ...

Less than 1 percent of the population has been diagnosed with Long QT syndrome – a rare heart condition that can cause chaotic, sometimes fatal, heart rhythms. Now, Virginia Tech researchers at the ...

Cardiologists say this basic self-check cannot diagnose heart disease, it can sometimes help detect early warning signs that ...

Background Persistent shockable rhythms (refractory to or recurring after three or more defibrillation attempts) are ...

An electrocardiogram (ECG) is the most common test to diagnose arrhythmia, and recording one as early as possible after heart palpitations can be helpful. Blood tests, stress tests, and chest x-rays ...

Seizures can disrupt the autonomic nervous system, potentially leading to cardiac arrhythmias, which are abnormal heart rhythms. Cardiac arrhythmias can cause convulsive syncope, a condition ...

Depending on how the heart’s electrical activity appears on an EKG, a doctor may diagnose coarse or fine ventricular fibrillation (VF). Coarse VF appears as larger waves on an EKG compared with the ...
