Dizzy Spells Revealed as Two Serious Heart Issues
4 Aug
Summary
- A 33-year-old woman discovered two rare heart conditions after dismissing symptoms.
- Her conditions, Wolff-Parkinson-White syndrome and a heart vein pouch, required surgery.
- A free workplace health assessment led to her life-changing diagnosis and treatment.

Denisa Fraser, 33, consistently downplayed her dizzy spells and heart palpitations, attributing them to stress or a lack of fitness. She believed these were normal sensations everyone experienced.
Routine heart tests during a free workplace health assessment at the Clevedon Clinic London Hospital in March 2026 prompted further investigation. Doctors discovered she had Wolff-Parkinson-White syndrome, a rare heart rhythm disorder, along with a significant coronary sinus diverticulum, a rare pouch in a heart vein.
These conditions complicated her treatment, necessitating two surgical procedures. The second operation, performed on May 22, lasted eight hours to address the abnormal electrical pathways in her heart. Following recovery, Denisa is now free of symptoms and encourages others not to ignore persistent health issues.
