What is the difference between ECG and a rhythm strip?

An EKG, also known as an ECG, measures the electrical waves and impulses of the heart. Electrodes, either 10 or 12 are placed on specific areas of the chest, arms and legs. Wires are connected to the electrodes. The impulses of the heart are picked up via the electrodes and sent through the wire to produce a graph of the heart's electrical conductivity. Heart rates and palpitations are commonly diagnosed. The rhythm strip is a more precise way to detect a problem on an otherwise normal EKG. The EKG is a snapshot, if you will, for a moment in time whereas the rhythm strip is a continuous feed.
