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.

Medtronic’s new extravascular ICD gains key approval

Unlike other ICDs, the lead for this new-look device is placed under the patient's breastbone, outside of their heart and veins.

FDA calls out weight loss pills for ‘hidden’ ingredient that puts health of heart patients at risk

The agency’s own analysis confirmed that these capsules contain sibutramine, which was removed from the market back in 2010 due to safety concerns

He led a team of engineers at the University of Missouri (UM) to develop a new soft, stretchable material that could potentially be used in wearable devices that gather key cardiovascular data. The group shared its findings in Science Advances, noting that the material creates such a small amount of pressure that users will not even notice they have it on.

Researchers design new material for wearable devices: ‘You cannot feel it, and you will likely forget about it’

The soft, stretchable material creates so little pressure that users will likely not even even be able to feel it.

AI model predicts risk of post-operative AFib

Post-operative atrial fibrillation was once viewed as a fairly insignificant issue, but more recent research suggests it can increase a patient’s risk of multiple adverse events.

New findings out of the University of Missouri suggests that the long-lasting impact of COVID-19 may not be quite as substantial as some researchers originally believed. The study’s authors evaluated nearly 50 different symptoms to see if they were more common up to one year after a person has been infected with COVID-19. They found, however, that this was true of just seven symptoms: heart palpitations, chest pain, shortness of breath, joint pain, hair loss, fatigue and obesity. #COVID19 #longCOVID

Heart palpitations, chest pain among the long-lasting side effects of COVID-19, new research confirms

“Before we examined the data, I thought we would find an ample amount of the symptoms to be specifically associated with long COVID, but that wasn’t the case," one researcher said.

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."
