Nursing care in atrial fibrillation: apical–radial pulse, stroke warning signs and teaching about anticoagulants
- Safe practice
In atrial fibrillation the nurse counts the apical pulse, watches for low cardiac output and stroke signs, and teaches safe use of anticoagulants.
What it is
Atrial fibrillation makes the pulse irregular, so a short radial count or an automatic monitor can be wrong. The nurse counts the apical pulse for a full minute, and the apical and radial pulse together when a pulse deficit is suspected. The nurse watches for signs that the heart is not pumping enough, such as dizziness, fainting, chest pain or breathlessness, and for stroke signs, because clots can form in the atria. Rate-control and anticoagulant medicines have checks before each dose. Teaching covers checking the pulse by hand, the stroke warning signs, bleeding precautions and not stopping medicines.
What it requires
- An accurate heart rate: apical count for one minute, and the apical–radial pulse when ordered.
- Watching for low cardiac output: tiredness, dizziness, fainting, chest pain, breathlessness, low blood pressure.
- Neurological checks for stroke warning signs.
- Safe administration of rate-control medicines and anticoagulants, with their checks.
- Teaching about the pulse, caffeine and alcohol, medicines and the emergency signs.
How it is applied (and why)
- Count the apical pulse for one full minute, with the radial pulse at the same time if a deficit is suspected — the radial count can miss beats.
- Look at the monitor rhythm and compare it with the patient — a rhythm change matters only together with how the patient is.
- Measure blood pressure manually if the automatic reading seems wrong — irregular beats confuse automatic devices.
- Ask about dizziness, palpitations, chest pain and breathlessness — these show low cardiac output.
- Check face, arm strength, speech, vision and balance each shift — atrial clots can cause a stroke.
- Before rate-control medicines, check pulse and blood pressure against the order's limits — they can slow the heart too much.
- Before an anticoagulant, look for bleeding and check the ordered tests — it prevents clots but raises bleeding risk.
- Prevent falls when the patient is dizzy or on anticoagulants — a fall can cause serious bleeding.
- Teach the pulse check, the medicines and the stroke and bleeding signs; check teach-back — the patient acts first at home.
In nursing practice
- Call at once for stroke signs: facial drooping, arm weakness, slurred or strange speech, sudden vision loss, loss of balance or a sudden severe headache.
- Call for chest pain, breathlessness, fainting, confusion or low blood pressure.
- Call for a very fast or very slow rate, or a new rhythm on the monitor with a change in the patient.
- Call for any bleeding in a patient on anticoagulants: urine, stools, gums, nose or a fall with a head knock.
- Advise the patient to limit caffeine and alcohol and to avoid stimulant drugs, as the team recommends.
Common mistakes
- Counting the radial pulse for 15 seconds and multiplying, in an irregular rhythm.
- Trusting an automatic blood-pressure or pulse reading without checking it by hand.
- Treating the monitor and not looking at the patient.
- Not writing down the time when stroke signs started.
- Teaching about anticoagulants without the bleeding signs and the medicine interactions.
Test yourself
Think of the answer, then tap the question to see it.
Why is the apical pulse counted for a full minute in atrial fibrillation?
Because the rhythm is irregular and some beats do not reach the wrist; a short radial count or an automatic device can be inaccurate.
What is a pulse deficit?
The difference between the apical rate and the radial rate counted at the same time; it shows beats that do not produce a pulse.
Which stroke signs should a patient with atrial fibrillation know?
Facial drooping, arm weakness, slurred speech, sudden vision or balance problems, and a sudden severe headache; call the emergency line at once.
Why is the onset time of stroke signs recorded?
Because the treatments that can be offered depend on how long ago the symptoms started.
