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.

Pre-procedure CT imaging benefits LAA occlusion in Henry Ford study

There is not agreement among the top structural heart experts if CT is required for left atrial appendage occlusion (LAAO), but a Henry Ford Hospital study shows it can improve outcomes.

TAVR outcomes take a hit when patients present with heart failure or hypertrophic cardiomyopathy

In-hospital mortality was especially high among TAVR patients presenting with hypertrophic cardiomyopathy, according to a new analysis.

KardiaBand outperforms Apple Watch in diagnosing AFib, but a cardiologist’s perspective is still crucial

The study's authors noted that the ECG acquisition technology in these wearable devices appears to be quite effective. The automated algorithms, however, could still be improved.

AFib patients more likely to be hospitalized for heart failure or bleeding following TAVR

The study, published in the American Journal of Cardiology, included data from more than 900 TAVR patients. Overall morality was 22.7% among patients with AFib and 14.4% among patients without AFib.

Leadless pacemaker technology moves toward dual-chamber pacing

Leadless pacemaker technology is expanding its ability to treat more patients with dual-chamber pacing.

AFib ablation makes financial sense, especially among heart failure patients

The additional costs associated with AFib ablation appear to be justified, researchers wrote.

AFib after surgery could be a warning sign of heart failure

Researchers studied data from more than three million patients, including approximately 76,000 who underwent heart surgery.
