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.

The Medtronic Micra leadless pacemaker implanted inside the heart. It is about the size of a large vitamin pill and is implanted using a catheter.

Medtronic receives CE mark approval for next-generation leadless pacemakers

The two devices, already approved by the FDA, were designed with batteries expected to last more than 15 years.

UCL Imaging vest screening cardiac conditions

New vest developed by cardiologists uses advanced heart imaging to screen for sudden cardiac arrest

“We identified a problem in cardiology,” one cardiologist explained. “Heart imaging has made remarkable progress in recent decades, but the electrics of the heart have eluded us."

The U.S. Food and Drug Administration (FDA) this week has the first cleared the pulsed field ablation (PFA) system, the Medtronic PulseSelect System for the treatment of both paroxysmal and persistent atrial fibrillation (AF).

FDA clears first pulsed field ablation system to treat AFib

"The PulseSelect PFA system ushers the EP community to a new era of safe, effective and efficient AF ablation that overcomes many challenges in our current practice," said Amin Al-Ahmad, MD, St. David's Medical Center in Austin, Texas.

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."
