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.

4 new medications and technologies that could transform cardiology in 2022

The FDA has already approved one of the medications, with a decision on another expected by the end of April. 

A dedicated Cardiac MRI scanner. The presence of myocardial fibrosis on cardiac MRI can help anticipate adverse arrhythmic events and  may offer a way to improve patient selection for cardiac implantable electronic devices (CIEDs). This is a dedicated cardiac MRI system at Baylor Scott White.

Cardiac MRI a powerful tool for predicting sudden cardiac death, arrhythmia after CIED implantation

The study's authors suspect their findings could improve patient selection for CIEDs. 

The Abbott Aveir DR dual-chamber leadless pacemaker recently had its first human implant occur in the Aveir DR i2i study pivotal trial.

First implant of dual-chamber leadless pacemaker completed in Abbott’s Aveir DR i2i pivotal trial

The investigational dual-chamber pacemaker is designed to provide synchronous, beat-by-beat pacing of the right atrium and right ventricle of the heart.

Driving restrictions for some ICD patients may need to change

Current restrictions for private driving after implantation of a secondary prevention ICD may keep patients from behind the wheel a little too long. 

Rest easy, heart patients—sudden cardiac death rarely happens during sex

Just 0.2% of cases evaluated in the study were tied to sexual intercourse.
