ECG Axis Interpretation ECG Axis Interpretation using the schematic illustration demonstrates the relationship between QRS axis and the frontal leads of the ECG. Normal Axis = QRS axis between -30° and +90°.Left Axis Deviation = QRS axis less than -30°.Right Axis Deviation = QRS axis greater than +90°.Extreme Axis Deviation = QRS axis between -90° … Read more

Definition: Failure to capture means when the pacemaker initiates a stimulus, but it fails to depolarise the myocardium. It is depicted on ECG by the presence of spikes of pacemaker but there is no associated depolarisation of the concerned chamber. Causes of failure to capture are: This ECG shows: Cause: Intermittent Failure to Capture. If … Read more

Hypocalcemia is defined as a calcium level below the normal range. The normal serum calcium level varies from 8.5 to 10.5 mg/dL and the normal level of ionized calcium is 4.2 to 4.8 mg/dL.
Overview of Hypercalcemia Hypercalcemia refers to the presence of elevated calcium level above normal. The normal level of total serum calcium varies from 8.5 to 10.5 mg/dL or for ionized calcium 4.2 to 4.8 mg/dL. When extracellular calcium is increased, the duration of the action potential is shortened. Shortening of the action potential duration results … Read more
Overview of Hypokalemia Hypokalemia is defined as the presence of serum potassium that is lower than normal. The normal value for serum potassium is 3.3 to 5.3 mmol/L. The most important ECG finding in hypokalemia is the presence of prominent U waves. As the hypokalemia becomes more profound, the amplitude of the T wave becomes … Read more
