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.

2 out of 5 AFib patients develop heart failure later in life
Stroke is typically seen as the biggest danger for patients after they receive an AFib diagnosis. This study, however, suggests heart failure could be an even bigger threat.

Extracorporeal CPR for out-of-hospital cardiac arrest: New research fails to provide answers

While a previous study had found that extracorporeal CPR outperformed conventional CPR among patients with out-of-hospital cardiac arrest, a newer analysis suggests the two treatment options result in similar outcomes.

An example if an implantable cardioverter defibrillator (ICD and its leads connected to the heart. As the leads or deveice wears out, there are recommendations to remove the leads and put in new ones. The most common causes of mortality during transvenous lead removal (TLR) in patients with cardiac implantable electronic devices (CIEDs) are infection and decompensated heart failure, according to new research published in JACC: Clinical Electrophysiology.Image courtesy of RSNA

Infection, heart failure the most common reasons for early mortality after transvenous lead removal

Early mortality specifically related to complications during the TLR procedure was quite rare.

Elevated uric acid levels linked to new-onset AFib

According to new data published in the Journal of the American Heart Association, atrial fibrillation can be added to the list of cardiovascular conditions associated with above-average uric acid levels.

Stroke patients with AFib face a higher mortality risk after thrombectomy

A comparative meta-analysis found similar procedural outcomes, but higher 90-day mortality—partially attributable to a higher rate of comorbidities.

COVID-19 infection and vaccination linked to debilitating heart condition—risk from vaccines ‘relatively slim’

Postural orthostatic tachycardia syndrome is a significant, but treatable condition. The risk among COVID-19 patients was considerably higher than the risk after vaccination, researchers explained.
