Heart rate is determined by the number of heartbeats per unit of time, typically expressed as beats per minute (BPM), it can vary with as the body's need for oxygen changes, such as during exercise or sleep.

Study reveals high incidence of orthostatic intolerance in children with long COVID

A new study from Kennedy Krieger Institute shows that the majority of children diagnosed with long COVID are likely to experience orthostatic intolerance (OI), a condition that causes the body to struggle with regulating blood pressure and heart rate when standing up.

Reduced heart rate variability linked to higher mortality in people with diabetes

Disruption to normal variations in daily heart rate (HR) is associated with a much higher risk of dying in people with type 1 and type 2 diabetes over 21 years, according to new research to be presented at this year's Annual Meeting of The European Association for the Study of Diabetes (EASD), Madrid (9-13 Sept).

Genetic variants linked to heart rhythm disturbances in Wolff-Parkinson-White Syndrome

Study by scientists at deCODE genetics/Amgen and collaborators in Denmark and the USA, on the genetics of accessory conduction pathways in the heart (Wolff-Parkinson-White syndrome), reveals that accessory pathways can cause rhythm disturbances, characterized by an overly fast heartbeat, which can be life-threatening.

Interrupting beta-blockers after myocardial infarction shows no advantage

The cardiovascular safety of interrupting beta-blocker could not be shown in comparison to continuation in patients with a history of myocardial infarction (MI) and there was no benefit to the patients' quality of life, according to late-breaking research presented in a Hot Line session today at ESC Congress 2024.

Recreational drug users three times more likely to experience repeat cardiovascular events

New research presented at this year's ESC Congress 2024 in London, UK (30 Aug – 2 Sept) shows that, among patients admitted to the intensive cardiac care unit (ICCU), those with a recent history of recreational drug use are three times more likely than those with no history to experience a repeat serious cardiovascular event within one year.

Exploring the impact of thyroid hormone on brain function

Thyroid hormone plays a key role in regulating a range of physiologic functions, including metabolism, temperature, heart rate, and growth. It accomplishes this impressive array of activities by interacting with almost every organ system in the body. Yet despite a long history of research on how thyroid hormone influences different organs, its effects on arguably the most crucial organ - the brain - have remained shrouded in mystery.

FDA-approved drug could revolutionize organ transplantation

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University report that they were able to successfully put tadpoles of Xenopus laevis frogs into a hibernation-like torpor state using donepezil (DNP), a drug approved by the FDA to treat Alzheimer's. The team had previously used another drug, SNC80, to achieve similar results in tadpoles and enhance the survival of whole mammalian hearts for transplants, but SNC80 is not approved for clinical use in humans because it can cause seizures. By contrast, DNP is already being used in the clinic, meaning it potentially could be rapidly repurposed for use in emergency situations to prevent irreversible organ injury while a person is being transported to a hospital.
