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.

Changing approaches to the treatment of sudden cardiac arrest

Preventing sudden cardiac arrest involves managing risk factors such as hypertension, hyperlipidemia and diabetes. We spoke to Christina Albert, MD, about this and much more at ESC 2023.

Attune Medical has been granted De Novo marketing authorization from the US Food and Drug Administration (FDA) for its ensoETM device to reduce the likelihood of ablation-related esophageal injury resulting from radiofrequency cardiac ablation procedures.

Cooling device now approved by FDA to reduce risk of ablation-related esophageal injuries

Already approved for temperature management, the single-use ensoETM device is now cleared for another use: minimizing the risk of potentially fatal injuries to the patient's esophagus during radiofrequency ablation procedures.

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."
