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.

FDA calls out weight loss pills for ‘hidden’ ingredient that puts health of heart patients at risk Alfia Weight Loss Capsules

FDA calls out weight loss pills for ‘hidden’ ingredient that puts health of heart patients at risk

The agency’s own analysis confirmed that these capsules contain sibutramine, which was removed from the market back in 2010 due to safety concerns

Researchers design new material for wearable devices: ‘You cannot feel it, and you will likely forget about it’

The soft, stretchable material creates so little pressure that users will likely not even even be able to feel it.

AI model predicts risk of post-operative AFib

Post-operative atrial fibrillation was once viewed as a fairly insignificant issue, but more recent research suggests it can increase a patient’s risk of multiple adverse events. 

Abbott FlexAbility Sensor Enabled Ablation Catheter FDA

Abbott gains new FDA approval for one catheter, CE mark approval for a second catheter

Both devices were approved for treating significant heart rhythm issues. 

Heart palpitations, chest pain among the long-lasting side effects of COVID-19, new research confirms

“Before we examined the data, I thought we would find an ample amount of the symptoms to be specifically associated with long COVID, but that wasn’t the case," one researcher said. 

Atrial Fibrillation and its location in the atrium detected using the Vektor arrhythmia detection software. COVID infection can cause the development of AFib, AF, in patients as a long-COVID symptom.

Peter Libby, MD, a cardiovascular medicine specialist with Brigham and Women’s Hospital, discussed the cases of AFib being seen in long-COVID patients.

Severe gum infections linked to heightened AFib risk

Researchers are still working to determine if gum disease leads to heart rhythm issues or if is actually the other way around. 

Extracorporeal CPR refractory out-of-hospital cardiac arrest

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.
