Question

select the correct answer.
how do doctors detect abnormalities in patients with the help of an ekg?
a. by determining changes in the heartbeat
b. by determining changes in blood pressure
c. by determining changes in blood components
d. by determining changes in arterial blood flow

Explanation:

An EKG (electrocardiogram) records the electrical activity of the heart. It helps doctors detect abnormalities by analyzing changes in the heartbeat's electrical patterns. Option B is about blood pressure (measured by devices like sphygmomanometers), option C about blood components (analyzed in blood tests), and option D about arterial blood flow (assessed by methods like Doppler ultrasound). So the correct answer is A as EKG relates to heartbeat changes.

Answer:

A. by determining changes in the heartbeat
