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.

Predictors of 1-year mortality after TAVR are significantly different among men and women

Atrial fibrillation and peripheral artery disease, for example, are both predictors of mortality among women, but not men.

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-cig. Using e-cigarettes may be associated with a heightened risk of atrial fibrillation (AFib) or other heart rhythm issues, according to new research published in Nature Communications.

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.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
