The Pulse: Ibn Sina’s Most Important Diagnostic Tool
The physician places two fingers on the patient’s wrist and waits silently for a few seconds.
This simple act is one of the oldest and most deeply rooted diagnostic methods in the history of medicine: taking the pulse.
Why was the pulse so important?
In the ages before laboratories, ultrasound and CT scans, the physician obtained most of his information from the patient himself. He looked, listened, asked questions and felt the pulse.
The pulse was like a voice heard through the fingers, reaching from inside the body to the outside.
Ibn Sina and the pulse
Ibn Sina gave the pulse special importance. He didn’t only judge it as “fast or slow”; he also examined:
- Speed
- Strength
- Size
- Regularity
- Quality
And he compared these in different conditions (age, season, sleep, eating, exercise, emotional states).
Historical sources show that a large section of Al-Qanun fi al-Tibb (The Canon of Medicine) is devoted to the pulse and its use in examination.
Is the pulse read on its own?
No. In Sina–Unani medicine, the pulse is assessed together with temperament, urine, the tongue, complexion, skin, sleep, appetite, digestion and elimination.
The pulse is one of the most valuable signs, but it is still part of the picture. Traditional medicine reads a sign within the whole of “alamat” (signs) and “dalil” (evidence).
Is the pulse still important today?
Yes. The pulse is part of the clinical examination today as well. New devices can measure the heartbeat and rhythm very precisely.
But there is a subtle difference here:
A device shows a number; the practitioner’s skilled hand notices in which person, and under which conditions, that number appeared.
90 beats a minute doesn’t mean the same thing in an excited young person, a patient with a fever or a tired older person.
Can taking the pulse be learned?
Reading the pulse is a skill that develops with experience and proper training. It takes time for the fingers to tell the pulse’s features apart.
An important note here: taking the pulse does not replace modern investigations such as blood-pressure measurement, an ECG or blood tests. Together with them, it helps to understand the person as a whole.
When should you see a doctor?
See a doctor if you notice the following in your own pulse:
- Marked irregularity (skipped or irregular beats)
- A pulse that is constantly very fast or very slow at rest
- A change in pulse that comes with dizziness, feeling faint, chest pain or shortness of breath
Frequently asked questions
Can temperament be understood from the pulse? In traditional medicine, the pulse is one of the signs that help in understanding temperament; but temperament is not determined by a single sign.
Do smartwatches replace taking the pulse? They measure the number, but they don’t assess the pulse’s qualities or the person’s whole picture.
Conclusion
The pulse is a bridge from Ibn Sina to today. It tells far more than a number, as long as it is read together with the body’s other signs.
