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.

Hypertension patients measured their blood pressure less frequently during the early months of the COVID-19 pandemic, according to new research published in Hypertension. In addition, when those patients did measure their blood pressure, the readings were less healthy than they had been before the pandemic.

Cardiologists shed new light on COVID-19 and cardiac arrhythmias

A higher rate of cardiac arrhythmias has been observed in hospitalized COVID-19 patients, but new research suggests there’s more behind that trend than the virus itself.

What does radiology have to do with climate change?

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."
