Although reaching target heart rate (HR) before coronary CT angiography (CCTA) is still of importance, adequate HR control remains a challenge for many patients. Purpose-built cardiac scanners may provide optimal image quality at higher HRs by further improving temporal resolution. We aimed to compa...
When accuracy and comfort are at the top of your priority list for a heart rate monitor, the Polar H10 is a great choice. This heart rate sensor is easy to use, and the ECG monitor is accurate. The unit is slim and lightweight. A soft and stretchy strap with a flat buckle that did...
Maximal rate of heart rate (HR) increase (rHRI) as a measure of HR acceleration during the transition from rest to exercise, or during an increase in workload, tracks exercise performance. rHRI assessed at relative rather than absolute workloads may track performance better, and a field test...

It generally contracts at a rate of 70 to 75 beats/minute in a healthy 70-kg person at rest. The normal heart rhythm, known as sinus rhythm, originates in specialized cardiac cells, called pacemaker cells, in the sino-atrial (SA) or sinus node and has been defined as a sinus node ...
AF in patients with chronic HF was associated with older age, reduced exercise capacity at baseline, and a higher overall rate of clinical events, but not a differential response to exercise training for clinical outcomes or changes in exercise capacity. (Heart Failure: A Controlled Trial Investiga...
“This update to Automatic Activity Detection is the result of years of innovation at Oura,” says Maris Jameson, Staff Product Manager. “The goal of the feature is to empower members to understand the impact of their activity on their health. It’s not just a heart rate feature; it’s...
be categorized as low risk.77Given that all prediction models are based on existing data and mostly use retrospective event rates to predict future events, underdiagnosis of events in past studies results in a lower even...
A continuous saline infusion at a rate of 1.2 mL/h was the minimum injection rate without allowing obstruction of the tip of the delivery needle because of freezing. On the basis of the results of the pilot experiments, an air flow rate of 300 mL/min and a saline infusion rate of 1.2...
heart rate profoundly, e.g. in excess of 10 beats per minute (bpm)10, subject-specific correction of JTp intervals or other methods reflecting the individuality of JTp/RR profiles would be needed. Nevertheless, in other cases, when the heart rate is changed only moderately (or not at all)...
