What is the difference between bradycardia and tachycardia?
A
bradycardia is a fast heart rate, while tachycardia is slow
B
bradycardia is a slow heart rate, while tachycardia is too fast
C
both have to do with a plaque build up
D
bradycardia is low blood pressure and tachycardia is high blood pressure
Explanation: 

Detailed explanation-1: -Tachycardia (tak-ih-KAHR-dee-uh) is a fast heart. The resting heart rate is greater than 100 beats a minute. Bradycardia (brad-e-KAHR-dee-uh) is a slow heartbeat. The resting heart rate is less than 60 beats a minute.

Detailed explanation-2: -A normal heart rate is usually stated as 60 to 100 beats per minute. Slower than 60 is bradycardia ("slow heart"); faster than 100 is tachycardia ("fast heart"). But some experts believe that an ideal resting heart rate is closer to 50 to 70.

Detailed explanation-3: -Tachycardia is fast heart rate. It occurs when your heart beats faster than 100 times per minute. Slow heart rate, on the other hand, is called bradycardia.

Detailed explanation-4: -Bradycardia is a slower than normal heart rate. A normal adult resting heart rate is between 60 – 100 beats per minute (bpm). If you have bradycardia, your heart beats fewer than 60 times a minute. Bradycardia (heart rate 40 – 60 bpm) can be normal when you’re sleeping.
