Dysrhythmia aka arrhythmia-Correct answer-abnormal cardiac rhythms

which can cause disturbances of rate, rhythm, or both rate and rhythm

bow are dysrhythmias identified-Correct answer Electrographic Waveform Analysis (ECG)

explain the heart's electrical system-Correct answer Each electrical signal (impulse) begius in a group of cells called the sinus node or sinoatrial (SA) node. The SA node is located in the right atrium. In a healthy adult heart at Test the SA node sends an electrical signal slower in very fit athletes. minute. (This rate rate may be

From the SA pump blood into the ventricles. right and left atria. It causes the airia to contract and

the atrioventricular (AV) node, located between the atria and the ventricles. Here, the signal slows down slightly, allowing the ventricles time to finish filling with

The electrical signal then leaves the AV node and travels to the ventricles. It causes the ventricles to contract and pump blood to the lungs and the rest of the body. The ventricles then relax, and the beurtbeat process starts all over again in the SA node.

normal sinus rhythm (characteristics)-Correct answer 1. Rate:60-100 bears/min
