Patients often tell me, “I have had an ECG, so I do not need a heart ultrasound.”
It is not quite that simple. An ECG and an echocardiogram examine different aspects of how the heart works.
An electrocardiogram records the heart’s electrical activity. It provides information about rhythm, heart rate, transmission of the electrical impulse and possible ECG changes.
An echocardiogram shows the heart’s structure and mechanical function: its chambers, walls, valves, contraction and blood flow.
Depending on the history and symptoms, one test, both tests or a different assessment may be needed. I do not start with a predetermined list of tests. I start with the question that needs an answer.
The information is general and is not a substitute for medical evaluation. Do not change your treatment without instructions. For urgent symptoms call 112 or 166.
