Pulse investigation (Nadi Pariksha)

Combination of Pulse
Vata pitta pulse
Not only imbalance in the doshas individually, but also the imbalance of the various degrees of each dosha and their combinations have to be studied through the pulse. A combination of vata and pitta is indicated by frequent association with the movement of snake and frog with the feel of pulse. The nadi or pulse in many cases of blood pressure may be classified as vata pitta pulse.
Vata kapha pulse
A combination of vata and kapha (also known as shleshma) presents pulse which has movements like that of a snake and a peacock. In a patient having swelling or edema combined with the weak action of aortic imbalance, as directed by the water hammer pulse, it may be said to be introduced in vata kapha pulse. There is a peculiar fullness in the artery combined with easy compression.
Pitta kapha pulse
The combined effect of vata and kapha pulse is denoted by jumping gait of a frog or toad and the alternative slow and steady gait of the peacock. In such a pulse we can include certain conditions of hypertension. This situation arises due to im balance in pitta and kapha dosha. The pulse in hypertensive patient can not be said to be belonging to certain particular dosha pulse. But it may be said that it has maximum involvement of vata and pitta. The pulse should in each case be studied very critically and the conclusion may depend upon the degree of vitiation of vata and pitta dosha. One case of hypertension may indicate more of vata and the pulse is thready and wavy without much jumping and yet the blood pressure reading is very high. In other care presentation the jumping may be more prominent. This is explained by the disturbance of the vaso motor system and the metabolic system which may be affected in different degrees.
Vata pitta kapha pulse or sannipaata nadi
This type of pulse categorizes in the patient in which all the three dosha are imbalanced. This is demonstrated by the alternative slow, intermitted, wickedness and indecisiveness movements. The pulsatile mode of the artery shows pulsation at one time and at the other time it disappears and then again appears. It is inconsistent and faint. The pulsation is sometimes felt in the arm or it may be only just detectable to the touch of the examining fingers. Different rishis have mentioned different views but sharanghdhar describes the movement of sannipaata pulse as similar to the gait of laavaka and titthiri birds because the birds flutter rapidly for some time and on a sudden, they stop their movements altogether, to repeat their quick movements once again.
Another rishi has compared the movement of sannipaata pulse with that of a mouse that has the tendency to run here and there, forwards and backwards. A movement of mouse is sometimes rapid and some time it is not moving.
Some authors and rishis have describes the sannipaata pulse as full and steady. This is due to the fact that in some cases of typhoid fever which are of the sannipaata type all the doshas i.e. vata, pitta and kapha are eventually excited and the pulse is full and fairly slow. The pulse is full due to kapha dosha, the jumping movement is due to the pitta presence and vata is pretty normal.
One thing can be said that vata vitiation is the most dangerous of all the situations. If it is in excess it leads to convulsions and fits and a person even can collapse. Vata is the king that leads the other two doshas i.e. pitta and kapha, either for good or bad purpose.
