sydänfilmiin
Sydänfilmiin, a Finnish term, translates to "heart film" and refers to an electrocardiogram (ECG or EKG). It is a non-invasive medical test that records the electrical activity of the heart. This activity is detected by small electrodes attached to the skin of the chest, arms, and legs. The electrodes pick up the tiny electrical changes that are caused by the heart muscle depolarizing and repolarizing during each heartbeat.
The information gathered by the sydänfilmiin is then displayed as a series of waves and lines on
