How to read ECG or Electrocardiogram, ECG and its Interpretation, Abnormal ECG Findings

 ECG- Electrocardiography

ECG CHANGES & INTERPRETATION

1. Shortened QT Interval- Hypercalcemia, certain genetic abnormalities, and Hyperkalemia.

2. Prolonged QT Interval- Hypocalcemia, certain genetic abnormalities.

3. Flattened or Inverted T waves- Coronary ischemia, hypokalemia, Left Ventricular hypertrophy, digoxin effect.

4. Hyperacute T waves- Most probably due to acute myocardial infarction, where T waves become more prominent, symmetrical, and pointed.

5. Peaked T wave, wide QRS Complex, prolonged PR intervals, reduced QT segment- Hyperkalemia, treat with calcium chloride, glucose, and insulin therapy, or dialysis.

6. Prominent U waves- Hypokalemia

ABNORMAL ECG READINGS

1. Peak T wave present in Hyperkalemia

2. Inversion of the T wave in Myocardial Infarction

3. Depressed ST Segment in Angina Pectoris

4. Elevated ST Segment in Myocardial Infarction

5. Widened QRS Complex in Arrhythmia
