Question

What are ECG signs that might indicate that hyperkalemia is present?

A) Tall, peaked T waves and prolonged PR interval
B) Flattened P waves and shortened QT interval
C) Inverted T waves and widened QRS complex
D) Presence of U waves and increased heart rate

Answer 1

ECG signs of hyperkalemia, a raised level of potassium in the blood, include tall, peaked T waves and a prolonged PR interval. These changes on an ECG are critical markers that indicate an underlying issue with the heart's electrical activity.

Step-by-step explanation:

ECG Signs of Hyperkalemia:

ECG signs that might indicate hyperkalemia include tall, peaked T waves and a prolonged PR interval. The presence of hyperkalemia, or elevated potassium levels in the blood, affects the heart's electrical activity as reflected on an ECG. In an ECG the normal tracing shows the P wave, QRS complex and T wave with their respective intervals and segments. Hyperkalemia can lead to characteristic changes such as the tall peaked T waves indicating potential heart issues that require medical attention.
