Question

Write everything you know about EMG not WRITTEN i want it TYPED using Microsoft word between 2 to 3 pages

Answer 1

Electrocardiogram producing process , yes that is ECG ( electrocardiography). The time Vs voltage of hearts electrical activity is interpreted into a graph with the help of electrodes

Resting 12 lead Electrocardiogram is the standard one that is used in the record process. They have 12 leads which includes limb lead and chest leads

Uses of electrocardiogram

1. It can be used to assess heart rhythm
2. It can be used to assess heart rate
3. All types of electrical conduction abnormalities
4. When blood flow to heart is low
5. Heart attacks can be detected

Electrocardiographic grid yes it is referred to as the markings or lines on the ECG paper . Both vertical and horizontal lines at 1mm regular interval

X axis of ECG

• It indicates the time duration.
• 1mm= 0.04 second

Y axis of ECG

• It has 1mm= 0.1 mVL

Leads of ECG

IT HAS 3 limb leads

1. Limb lead 1- right arm and left arm
2. Limb lead 2-right arm and left leg
3. Limb leads 3- left arm and left leg

Unipolar limb leads

1. aVR lead
2. aVL lead
3. aVF lead

Unipolar chest leads are

1. V¹
2. V²
3. V³
4. V⁴
5. V5
6. V6

Major waves in ECG are

1. P wave
2. Q wave
3. R wave
4. S wave
5. T wave

Major complex in ECG

1. P wave that indicated atrial complex
2. QRS wave that indicates initial ventricular complex
3. T wave for final ventricular complex
4. 4 QRST. Ventricular complex
