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.

AFib ablation is effective for HCM patients, leading to long-term rhythm control

Overall, 60% of patients demonstrated complete freedom from recurrences of atrial fibrillation or atrial tachycardias.

Nighttime cardiac arrest, a ‘perplexing and devastating phenomenon,’ more common among women

Physicians may want to think twice before prescribing certain medications, including drugs for pain or depression, to some female patients, the authors observed.

Alcohol consumption, even just a daily glass of wine, leads to a heightened risk of AFib

Researchers tracked data from more than 107,000 patients, completing what is believed to be the largest study of its kind.
