Frequent Occurrence of Heart Rhythm Disorder in Long COVID Patients
A groundbreaking study reveals that nearly one-third of long COVID patients, especially middle-aged women, develop POTS, a heart rhythm disorder causing dizziness, fatigue, and impaired quality of life.
A recent study conducted by researchers at Karolinska Institutet highlights a significant link between long COVID and an uncommon heart rhythm disorder known as Postural Orthostatic Tachycardia Syndrome (POTS). The study reveals that nearly one-third of individuals experiencing severe long COVID exhibit symptoms consistent with POTS, predominantly affecting middle-aged women who were previously healthy and physically active. POTS is characterized by an abnormal increase in heart rate upon standing, leading to symptoms such as dizziness, fatigue, brain fog, and difficulty concentrating, which often overlap with long COVID symptoms.
The study involved 467 non-hospitalized patients tested around 12 months after their initial COVID-19 infection. Results showed that 31% received a formal POTS diagnosis, while another 27% displayed symptoms but did not meet all diagnostic criteria. Patients diagnosed with POTS experienced higher heart rates during physical exertion and reported a lower quality of life.
Importantly, POTS can be diagnosed with simple, cost-effective tests available at various healthcare levels. Effective treatments exist to alleviate symptoms and improve daily functioning. Researchers recommend that clinicians evaluate long COVID patients who demonstrate a significant increase in heart rate when changing posture or during exertion, especially if they experience dizziness, cognitive difficulties, or prolonged fatigue.
Follow-up studies are planned to assess the long-term recovery and functional outcomes of affected patients, including those who required hospitalization for COVID-19. This research underscores the importance of recognizing and managing POTS in the context of long COVID, facilitating better patient care and quality of life.
