Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Hydroxychloroquine unable to limit spread, or severity, of COVID-19 after exposure

There are no benefits to treating patients with hydroxychloroquine after they have already been exposed to COVID-19, according to a new study published in the New England Journal of Medicine.

AFib patients should limit alcohol consumption—it might just save their life

Drinking too much alcohol in a given week can put AFib patients at an increased risk of stroke, embolism and other significant health issues.

82% of AFib patients have undiagnosed sleep apnea, highlighting the importance of screening

Obstructive sleep apnea is known to be a "modifiable risk factor" for recurrent AFib, the authors explained.

Aortic stenosis patients with AFib may experience more complications after valve replacement

The analysis, published in the American Journal of Cardiology, included data from more than 741,000 adult patients with aortic stenosis.

Ablation outperforms drug therapy as an initial treatment for atrial fibrillation

Drug therapy is typically recommended for the initial treatment of patients with atrial fibrillation, but new research suggests there could be a more effective way.

Fish oil and vitamin D supplements don’t prevent atrial fibrillation

Both supplements are still perfectly safe for patients to take for other reasons, researchers emphasized. 

COVID-19 patients with abnormal heart rhythms face a greater risk of death

"Patients and physicians need to monitor for these arrhythmias closely and treatments needs to be timely," one researcher warned.
