Question
12 out of 13
 

QRS complex indicates which of the following:



A Atrial repolarization

B Ventricular repolarization

C Atrial depolarization

D Ventricular depolarization

Ans. D Osborne J wave

ECG flndings in: -

1. Hypothermia Elevation of the j-point — Osborne wave. Q

2. Hyperkalemia peaking (tenting) of T-wave, -P-wave amplitude, widening of the QRS interval, cardiac arrest with sine wave (in severe Hyper kalemia)Q

3. Hypokalemia Prominent ‘U’-wave, prolongation of ‘QT’ interval. Q

4. Hypocalcemia Prolong QT interval Q

5. Hyper calcemia — Short QT interval.Q

6. Digitalis toxicity —short QT interval with “scooping” of the ST-T wave comples (i.e. Depression of ST-T segment) Q

7. Sub arachnoid Hemorrhage “CVAT-wave” pattern marked QT prolongation with deep wide T-wave inversions Q

8. M.I T-wave inversion Q
