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.

Medical marijuana linked to a higher risk of heart rhythm issues

The new analysis, presented at ESC Congress 2022, found that a medical marijuana prescription for chronic pain may increase a person's overall arrhythmia risk. 

FDA announces recall of nearly 88,000 implantable cardiac devices due to risk of serious injury or death

The recall is related to short circuit protection (SCP) alerts that were causing the devices to send reduced-energy electric shocks. There have been 27 customer complaints about the issue so far.

CathVision’s ECGenius EP Recording System, a new solution designed to capture high-fidelity, low-noise electrocardiogram (ECG) recordings for the diagnosis and treatment of arrhythmias such as atrial fibrillation (AFib).

Heart rhythm specialists raise $7.2M to fund advances for FDA-cleared ECG system

The new funding all came from existing investors. “Reinvesting in the company demonstrates confidence in our innovation," CathVision's CEO said about the news. 

Study the signs: The most common symptoms of 6 cardiovascular diseases

A new scientific statement details the most common symptoms associated with heart attacks, heart failure and other cardiac conditions. Importantly, the authors wrote, clinicians must remember that symptoms can vary between men and women.

Atrial cardiomyopathy tied to a higher risk of dementia, even when patients show no signs of AFib or stroke

Researchers examined decades of data from more than 5,000 patients, sharing their findings in the Journal of the American Heart Association.

AFib screening using wearable devices found to be cost-effective for patients as young as 50

While current guidelines endorse screening for people aged 65 and above, a massive simulation published in JAMA Health Forum suggests that cost-effectiveness may extend to even younger age groups.

Transcatheter mitral valve repair (TMVr) is associated with “promising” short-term outcomes among patients with a history of cancer, according to new research published in the American Journal of Cardiology.

Risk of death increases when TEER patients present with hypertrophic cardiomyopathy

A team of Cleveland Clinic researchers tracked data from nearly 23,000 patients, sharing their findings in the American Journal of Cardiology.
