What are the 5 waves of ECG?
They are called P, Q, R, S, and T wave respectively. The group of Q, R, and S wave is called as QRS complex.
What are the 12 leads of ECG?
The standard EKG leads are denoted as lead I, II, III, aVF, aVR, aVL, V1, V2, V3, V4, V5, V6. Leads I, II, III, aVR, aVL, aVF are denoted the limb leads while the V1, V2, V3, V4, V5, and V6 are precordial leads.
Where do you place a 5 lead ECG?
5-lead ECG Placement
- White is on the right side, just below the clavicle (midway)
- Black is on the left side just below the clavicle.
- Brown is in the 4th intercoastal space, just to the right of the sternum.
- Green is on the right on the lower edge of the rib cage.
- Red is on the left of the lower edge of the rib cage.
Why it is called 12-lead ECG?
The standard ECG – which is referred to as a 12-lead ECG since it includes 12 leads – is obtained using 10 electrodes. These 12 leads consists of two sets of ECG leads: limb leads and chest leads. The chest leads may also be referred to as precordial leads.
What QRS means?
The QRS complex represents the depolarization of ventricles. It shows the beginning of systole and ventricular contraction. The QRS complex or wave starts with a small deflection downwards, represented by the point Q. It follows the P wave.
What is a 3 lead ECG used for?
3-lead ECG 3-lead ECGs are used most often for recording a 24-hour reading. A 24-hour reading is a frequently used tool for the diagnosis of heart problems and is reimbursed as a long-term reading.
