An ECG test is a non-invasive procedure that records the electrical activity of the heart at rest. Insight Medical Imaging offers ECG exams on a walk-in basis at most of our locations across Alberta. All ECG exams require a doctor’s requisition, Alberta Health Care card, and photo identification. ECG tests can be used to assess heart rate, rhythm, blood pressure, and other symptoms such as palpitation or chest pain.

An ECG provides imformation about what?

An ECG provides information about the wearer of the ECG's heartrate and rhythm of the heart. It provides information about wether it is normal or abnormal.


What does ECG measure?

The electrical activity of the heart.


In a normal ECG tracing?

the repolarization of the atria is hidden by the QRS wave


Who is required to fast prior to an ecg test?

Typically, patients are not required to fast before an ECG (electrocardiogram) test, as it primarily measures the heart's electrical activity and does not involve food intake. However, if the ECG is part of a broader diagnostic workup that includes other tests, such as blood tests, fasting may be necessary for those specific procedures. It's always best to follow the specific instructions provided by your healthcare provider.


What is a lead on a ECG and what information does it provide?

A lead on an electrocardiogram (ECG) refers to the configuration of electrodes placed on the body to measure the electrical activity of the heart from specific angles. Each lead provides a different view of the heart's electrical activity, allowing clinicians to assess heart rhythm, identify abnormalities, and diagnose conditions such as arrhythmias, ischemia, or infarction. Common leads include the standard limb leads (I, II, III) and precordial leads (V1-V6), each contributing unique information about different heart regions. By analyzing the data from these leads, healthcare professionals can gain insights into the heart's overall health and function.
