Tachycardia is defined as	A heart rate faster than normal
Bradycardia is defined as	A heart rate slower than normal
If the ECG recording appears as a series of interruptions on the baseline the medical assistant should	Check the cable connections to the electrodes
In which direction should lead connectors on electrodes be pointed when attached to the patient in preparation for the ECG	Towards the center of the body
On an ECG recording five millimeter boxes are seen between to r waves, what is the patient’s heart rate per minute	60 bpm
If the ECG recording appears as a series of small uniform spikes in the baseline the medical assistant should do	Check for nearby electrical appliances
If the ECG recording appears with the baseline rising and falling the medical assistant should	Ask the patient to remain as still as possible, help the patient to relax and stay warm
