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.

Dual antithrombotic therapy reduces risk of major bleeding events in AFib patients undergoing PCI

Dual antithrombotic therapy combined with the blood thinner dabigatran and a P2Y inhibitor could be a more effective—and less risky—alternative to standard care in atrial fibrillation (AFib) patients undergoing percutaneous coronary intervention (PCI), a study published this month in the New England Journal of Medicine reports.

Abbott smartphone-compatible cardiac monitor gains FDA clearance

Abbott has received FDA clearance for its smartphone-compatible insertable cardiac monitor (ICM), the healthcare company announced Oct. 23. The device allows a patient to actively monitor his heart activity while giving physicians the ability to identify arrhythmias remotely.

Thyroid hormone levels tied to increased risk of AFib

Higher levels of thyroid hormone in the blood were associated with an increased risk of atrial fibrillation (AFib), even when the levels were within normal range, according to an analysis of 11 studies containing more than 30,000 people.

Icelandic researchers ID genetic variant that increases risk of AFib

Icelandic researchers have uncovered two novel genetic variants of atrial fibrillation (AFib), one of which could increase the risk of developing AFib for susceptible patients.

FDA Issues Claim for Unequal HART Device

GLEN MILLS, Pa., Oct. 17, 2017 — Unequal®, a leading manufacturer of sports protective gear, announced that the Food and Drug Administration has determined that Unequal's patented HART® CC Pad device, found in every Unequal HART chest protector, can improve safety on the playing field.

AHA: Men develop AFib a decade before women do; BMI linked to increased risk

A large-scale study of nearly 80,000 patients suggests men develop atrial fibrillation (AFib) an average of 10 years earlier than women, according to researched from the American Heart Association.

New mobile apps for patients, healthcare providers work together to treat AFib

Heart experts have launched a pair of smartphone and tablet applications designed to treat atrial fibrillation (AFib), the most common cardiac rhythm disorder.

Researchers analyze long-term benefit, safety of ICDs in patients with Brugada syndrome

Patients with Brugada syndrome (BrS) benefit from implantable cardioverter defibrillators (ICDs) but are at significant risk of device-related complications, according to the longest-term study to date on the topic.
