Dysrhythmia aka arrhythmia - Correct answer abnormal cardiac rhythms
which can cause disturbances of rate, rhythm, or both rate and rhythm
how are dysrhythmias identified? - Correct answer Electrographic Waveform Analysis (ECG)
what controls the rate and rhythm of the
explain the heart's electrical system - Correct answer Each electrical signal (impulse) begins 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 rest, the SA node sends an electrical signal to begin a new heartbeat 60 to 100 times a minute. (This rate may be slower in very fit athletes.) DYSKATHMA
From the SA node, the electrical signal travels through the pump blood into the ventricles. right and left atria. It causes the atria to contract and
The electrical signal then moves down to a group of cells called 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 blood. RELIAS
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 heartbeat process starts all over
