Question | Answer |
Transmission of EKG signals via radio waves | Telemetry |
On an EKG tracing, an indication of the absence of electrical charge or activity represents | Baseline |
A beat arising from a focus outside the heart is | Ectopic beat |
Epicardium | Outermost layer of the heart |
Sudden rush of blood pushed into the ventricles as a result of atrial contraction is | Atrial kick |
The U wave represents | Repolarization |
Not necessary in administering an EKG | Sterilizing the leads |
Which type of lead is lead III | Bipolar limb lead |
Represented by the Q-T interval | One ventricular contraction and recovery |
Leads aVR, aVL, and aVF are | -Limb leads and Augmented leads(aka Unipolar leads) (BOTH OF THESE) |
Successful depolarization of the atria or ventricles by an artificial pacemaker is called | capture |
Not a cause of artifacts on an EKG | Clean sensors |
Augmented leads are also known as | Unipolar leads |
The QRS complex represents | Contraction of the ventricles |
The coronary sinus empties into the | Right atrium |
A falling or drooping of the heart | Cardioptosis |
Measurement of the atrial rate on the EKG tracing | P waves |
Lead II is a(n) | Bipolar limb lead |
The heart's conduction system is measured by | Exercise electrocardiography |
Which of the patient's limbs serves as an electrical ground | Right leg |
Depolarization of fast cells is dependent on which electrolytes | Sodium |
Device that may deliver a small amount of electrical energy to cause myocardial depolarization | Electronic pacemaker |
Cardiomegaly often occurs in which condition | Congestive heart failure |
Which waves on an EKG represent the slow recovery of repolarization | U wave |
When ventricular rhythm is extremely slow and irregular, and it becomes slower to the point of asystole, it is called | Agonal rhythm |
