Question 1: V3

Answer:

The electrod is placed midway between V2 and V4

Question 2: V1

Answer:

The electrode is placed at the 4th intercostal space just to the right of the sternum

Question 3: What do the leads do on EKG machine

Answer:

They carry the cardiac electrical impulses into the machine

Question 4: Interupted Baseline Occurs When?

Answer:

Occurs when the electrical connection has been interrupted or when there is noticable movement from the patient

Question 5: Describe Chest Leads

Answer:

Precordial leads V1, V2, V3, V4, V5, V6, Unipolar and provide a transverse plane view of the heart. THe V means chest and each number represents a specific loacation on the chest

Question 6: How Many Electrodes are placed on the chest, arms and legs

Answer:

10

Question 7: Name 3 ECG Capabilities

Answer:

Diagnose Cardiac Disease Determine an indivuals engery performance Prescribe a exersize plan

Question 8: What do the EKG Electrodes do?

Answer:

They pick up the electrical activity of the heart.

Question 9: Describe bipolar leads

Answer:

They are the first 3 lead also called the standard leads. They each use 2 limb electrodes to record the hearts electrical activity. The right arm electrode is the negitive pole, left arm or left leg is the postitive pole. Leads are I, II, & III

Question 10: How does Somatic Tremor show up?

Answer:

Shows up as a jagged peak of irregular height and spacing with a shifting base.

Question 11: What are the 3 augments leads and where are?

Answer:

Right Arm (AVR), Legt Arm (AVL) and Left Leg (AVF)

Question 12: How does Alternating Current show up? (AC)

Answer:

Shows up as a uniform small spikes on the paper

Question 13: Artifact

Answer:

Is a unwanted erratic movement of the stylus on the paper resulting from outside interference.

Question 14: What is standardization of the ECG

Answer:

An iternational agreement so that an ECG can be interpertated in teh sameway anywhere in the world.

Question 15: Precordial leads are?

Answer:

Chest leads that are unipolar

Question 16: V5

Answer:

The electrode is placed horizontal to V4 in the left Axillary Line

Question 17: What is the result of an artifact?

Answer:

The stylus gradually shifts away from the center of the paper-caused from movement from the pt or poor electrode attachement. -

Question 18: AVF

Answer:

(Augmented Volgage Left Leg) Records the electrical activity of the inferior surface of the left ventricalfrom the left leg

Question 19: 12 EKG leads consists of

Answer:

(3 Limb Leads (1) lead is the ground lead), I, II, III. 3 Augment leads AVR, AVL & AVG and the 6 Precordial Leads V1, V2, V3, V4, V5, and V6

Question 20: AVR

Answer:

(Augmented Voltagle Right Arm)Records the electrical activity of the atria from the Right Shoulder. P waves and Qrs complex are deflected below the baseline

Question 21: V4

Answer:

The electrode is placed in the 5th intercostal space at the left of the midclavicular line

Question 22: What do the Horizontal plane leads include

Answer:

They include the six precordial /chest leads

Question 23: Main types of artifacts

Answer:

Wandering baseline, Somatic Tremor, Alternating Current (AC), & interupted baseline

Question 24: Describe augments leads

Answer:

Next 3 leads, they are combined aVR, AVL, AVF, the electrical activity recorded by these leads is relitively small and therefore amplified (augmented). Unipolar leads w/ single positive electrode that uses the (R) leg for grouding

Question 25: Lead III records?

Answer:

Lead III records the electricle activity of the inferior surface of the left ventricle

Question 26: Precordial leads measure?

Answer:

The electrical current among 6 specific points at the chest wall and a point within the heart

Question 27: What is Alternating Current Caused by?

Answer:

Electrical current by nearby equipment

Question 28: How may leads come after the Standard or Bipolar leads

Answer:

3
