12-lead resting electrocardiogram (ECG) is a non-invasive test that records the heart’s electrical activity at rest. It is one of the most common first-line investigations in the evaluation of cardiovascular symptoms and risk. The ECG provides essential information about heart rhythm, conduction, evidence of a previous heart attack, and other electrical abnormalities that may point to underlying cardiac disease. At Prime Cardiology we use high quality, hospital grade ECG technology to ensure accurate and reliable tracings. It is a fundamental tool in the assessment of symptoms such as chest pain, palpitations, shortness of breath or dizziness, and it supports early diagnosis across a wide range of clinical scenarios.
An ECG is often the sensible starting point when you have new cardiac symptoms, an abnormal pulse, or cardiovascular risk factors. It is quick, painless and widely used as a baseline before more detailed testing. Because it captures only a brief moment, an ECG may be normal between episodes, so if your symptoms come and go your cardiologist may recommend longer monitoring such as a Holter or HeartBug.
A technician places small sticky electrodes on your chest, arms and legs. You lie still for a few seconds while the recording is taken. There is no preparation required and you can drive and return to normal activity straight away.
An ECG is valuable as a baseline and for the assessment of chest pain, palpitations, syncope and suspected conduction disease. Where the resting ECG is normal but symptoms are intermittent, consider referral for ambulatory monitoring or a rapid access chest pain review. Results are reported by a cardiologist with clinical correlation.
