Palpitations are an awareness of your own heartbeat — felt as racing, pounding, fluttering, skipping or stopping. They are one of the most common symptoms that prompt a cardiology referral.
Dr Matthew Balerdi provides rapid assessment for palpitations in Hull, Grimsby and Scunthorpe, including same-week ECG, ambulatory rhythm monitoring with the Zio XT patch, and echocardiography.
Palpitations describe a heightened awareness of your own heartbeat. People experience them differently — as a racing sensation, a pounding in the chest, a fluttering feeling, a skipped beat, or even the heart seeming to stop momentarily.
The key principle is that palpitations are a symptom, not a diagnosis. They can be caused by a wide range of underlying rhythms, from completely harmless extra beats to arrhythmias that require treatment. The purpose of assessment is to identify what is producing the sensation.
Racing
A fast, regular or irregular heartbeat
Pounding
A forceful beat felt in the chest, neck or throat
Fluttering
A rapid, light sensation in the chest
Skipping or stopping
A missed beat followed by a stronger thud
The way palpitations feel can provide important diagnostic clues:
Suggests ectopic beats — usually benign extra beats
Suggests supraventricular tachycardia (SVT)
Suggests atrial fibrillation (AF)
Suggests ventricular tachycardia (VT) — seek urgent assessment
The majority of palpitations are caused by harmless mechanisms:
Some palpitations reflect arrhythmias or conditions that need evaluation:
The goal of investigation is to capture your heart rhythm during symptoms. Dr Balerdi will select the most appropriate tests based on how often your palpitations occur.
A detailed history of your symptoms is the most important first step. A 12-lead ECG checks for resting rhythm abnormalities, and blood tests screen for anaemia, thyroid dysfunction and electrolyte imbalance.
Options include a 24–48 hour Holter monitor for daily symptoms, the Zio XT patch worn for up to 14 days for less frequent episodes, a KardiaMobile device for on-demand recording, or an implantable loop recorder for very infrequent events.
An echocardiogram may be recommended when palpitations are accompanied by significant symptoms or when structural heart disease is suspected. It provides a detailed assessment of heart structure and function.
Most palpitations are not emergencies, but some warrant urgent attention. Use the guidance below to decide on the appropriate level of response.
Based on your symptoms and clinical assessment, Dr Balerdi may recommend one or more of the following investigations.
