ECG and Holter Monitor ECG

ECG, also referred to as EKG, is the abbreviation of the word electrocardiogram – a heart test that tracks the electrical activity of your heart and records it on a moving paper or shows it as a moving line on a screen. An ECG scan is used to analyze the heart’s rhythm and detect irregularities and other cardiac issues that might lead to serious health problems such as a stroke or heart attack.

To get an ECG trace, an ECG monitor is needed to record it.

As the electrical signals move through the heart, the ECG monitor records the strength

and the timing of these signals in a graph called a P wave.

Traditional monitors use patches and wires to attach electrodes to the body and communicate

the ECG trace to a receiver.

The length of an ECG test varies depending on the type of the test being performed.

Sometimes it can take a few seconds or minutes. For longer, more continuous monitoring

there are devices that can record your ECG for several days or even a week or two.

Holter monitor

The electrical activity of the heart is typically recorded over a period of 24 hours.

Three or four electrodes are attached to your chest, and a small recording device is worn on a belt or

hung around your neck. The ECG data are then transferred to a computer

later on at the doctor's office for analysis. To do this, the doctor also needs information about your

daily schedule (like unusual events, physical activity and sleep). A Holter monitor may be used if,

for instance, you only have an irregular heartbeat some of the time and it doesn't show up in a “normal” ECG.
