What is the heart rate threshold for identifying bradycardia on an EKG?

Bradycardia is defined as a slower than normal heart rate, specifically one that is less than 60 beats per minute in adults. When interpreting an EKG, healthcare professionals look for heart rate patterns to determine if bradycardia is present. A heart rate less than 60 beats per minute signifies bradycardia, indicating that the heart is beating more slowly than what is typically considered healthy for an adult resting heart rate, which usually ranges from 60 to 100 beats per minute.

Therefore, identifying a heart rate threshold of less than 100 is essential for diagnosing bradycardia, as anything below this value could include bradycardia, depending on the exact rate. The other options do not accurately reflect the definition of bradycardia, which focuses specifically on heart rates that fall below this threshold.
