The Importance of ECG
A 12-lead Electrocardiogram (ECG) is a fundamental test for anyone experiencing palpitations. It records the heart's electrical signals and can detect any arrhythmias or structural heart issues. This test is quick and often part of the initial evaluation for palpitations.
Ambulatory Monitoring
If the ECG doesn't reveal the cause, ambulatory cardiac monitoring may be used. This involves wearing a monitor for a period, ranging from a day to weeks, to catch any irregularities over time. It’s particularly useful for intermittent palpitations not captured during a brief ECG.

When Is an Echocardiogram Needed?
An echocardiogram is suggested if a structural heart problem is suspected. This test uses ultrasound to create images of your heart, helping to identify issues like valve problems or cardiomyopathy. It's a non-invasive procedure that offers detailed insight into heart function.
FAQs
What is the first test for palpitations?
A 12-lead ECG is typically the first test performed.
How can long-term monitoring help?
It can detect intermittent issues not found in a short ECG.
When is an echocardiogram recommended?
If a structural heart issue is suspected.
The Bottom Line
Testing is crucial for diagnosing the underlying cause of palpitations.
