Radials, Brachials, Carotids, Femorals
In which of the following conditions does heart rate typically decrease?
Heart block
Which of the following situations is most likely to result in increased heart rate?

Study Notes
Arterial Pulse Examination
- Examining arterial pulses helps assess cardiovascular health and detect any abnormalities.
Pulse Locations and Timing
- The femoral pulse has a time lag of approximately 70-80 milliseconds from cardiac systole.
- The radial pulse is located at the wrist.
Heart Rate Measurement
- Heart rate can be measured from an ECG (electrocardiogram) by counting the number of QRS complexes per minute.
Pulse Examination in Limbs and Neck
- To assess the arterial pulse in all 4 limbs and both sides of the neck, the following arteries should be examined:
- Brachial arteries in the upper arms
- Radial arteries in the wrists
- Femoral arteries in the groin
- Dorsalis pedis arteries in the feet
- Posterior tibial arteries in the legs
- Carotid arteries in the neck
Heart Rate Changes in Different Conditions
- Heart rate typically decreases in:
- Trained athletes
- Heart rate is likely to increase in:
- Stressful or anxious situations
- During exercise
- Due to certain medications
- A common cause of tachycardia (rapid heart rate) is:
- Stress and anxiety
