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.

ECG data from historic pig heart transplant surprise electrophysiologists

“This was a true milestone for research on xenotransplantation," one specialist said. The full analysis is scheduled to be presented at the American Heart Association's Scientific Sessions 2022 in Chicago.

Dapagliflozin still beneficial for HFpEF, HFmrEF patients with AFib

While some heart failure medications are less effective in patients with concomitant atrial fibrillation, new research suggests that is not the case for dapagliflozin.

E-cigarettes linked to AFib, other heart rhythm issues in ‘highly concerning’ new study

“The findings of this study are important because they provide fresh evidence that the use of e-cigarettes could interfere with normal heart rhythms—something we did not know before,” according to one specialist.

Researchers awarded $31M to study conduction system pacing among heart failure patients

“Once the study begins, it will likely be one of the largest heart pacing clinical trials happening in the world over the next few years," one specialist said.

LAAO equally effective for men and women, new long-term study confirms

In-hospital complications are more common among women who undergo LAAO than men. However, according to a new study in JACC: Cardiovascular Interventions, men and women have similar long-term outcomes.

Smartphones show potential to double as electronic stethoscopes

The application, called Echoes, was designed with help from the British Heart Foundation and Evelina Children’s Heart Organization. It uses an iPhone's built-in microphone to capture recordings of the user's heart.
