Heart Palpitations Testing in London
By Dr Caplin Merijo & Mr Tharb Faisl
When your heart starts to race, flutter, or skip beats, it’s not just uncomfortable — it can be downright scary. Whether it’s stress, caffeine, or something deeper, don’t wait in worry. At Marylebone Diagnostic Centre, we provide private heart palpitations testing in London with same-day ECG and blood test appointments, helping you get answers quickly and discreetly.
What Are Heart Palpitations?
Heart palpitations are sensations where you become suddenly aware of your heartbeat. It might feel like:
- A rapid or pounding heart
- Fluttering in the chest
- Skipped or paused beats
- A sudden “flip-flop” or thud in your chest
While most cases are harmless, recurrent or unexplained palpitations can sometimes indicate:
- Anaemia
- Overactive thyroid
- Electrolyte imbalances
- Stress hormone spikes
- Rare cardiac rhythm disorders
The only way to be sure? Proper testing.
