Question

What is the cause of peaked T waves (generalized), prolonged PR and QRS waves, and sine waves?

1) Hyperkalemia
2) Hypokalemia
3) Hypercalcemia
4) Hypocalcemia

Answer 1

Peaked T waves, prolonged PR and QRS waves, and sine waves on an ECG can be caused by hyperkalemia (high potassium levels) and hypocalcemia (low calcium levels).

Step-by-step explanation:

Peaked T waves (generalized), prolonged PR and QRS waves, and sine waves are all abnormal findings on an electrocardiogram (ECG) that can be indicative of certain medical conditions. In this case, the possible causes of these ECG abnormalities are hyperkalemia (high potassium levels) and hypocalcemia (low calcium levels). Hyperkalemia can lead to peaked T waves, prolonged PR and QRS waves, and sine waves, while hypocalcemia can also cause prolonged PR and QRS waves and flattened or absent T waves.
