Table 4

Test cases showing result with inference system.

Test caseResult (shows the probability of heart attack based on the rule mapped)

“RestingBP_RBP:” 200Outcome (%) = 57.57
Here, it is clear that RBP, SCH, RHR, and MHR and higher than usual but rest features have controlled data so here probability of heart attack is 50+% means person is at risk but not much. This case be measured as moderate-high risk.

“RestingBP_RBP:” 130Outcome (%) = 34.96
Here, most of the parameters are in good shape but still features like RES, RBP, and MHR are more than usual but in control. So, this case could be considered as low-moderate risk.

“RestingBP_RBP:” 105Outcome (%) = 34.84
Here, most of the parameters are in good shape but still features like CPD, RHR, and MHR are more than usual but in control. So, this case could be considered as low-moderate risk.

“RestingBP_RBP:” 110Outcome (%) = 33.35
This is a heart patient but his parameters other than CPD and RES are normal so is at low-moderate risk.

“RestingBP_RBP:” 139Outcome (%) = 57.57
This is a heart patient, and his few parameters are beyond normal so is at moderate-high risk.

“RestingBP_RBP:” 140Outcome (%) = 85.35
This is a heart patient, and his most of the parameters are beyond normal so is at critical risk.

“RestingBP_RBP:” 140Outcome (%) = 57.57
Here, parameters are more or less same as above case but this patient is not a heart patient so will be at moderate-high risk.

“RestingECGResult_RES:” 0

“RestingBP_RBP:” 83Outcome (%) = 0
Here, parameters are normal and also this patient is not a heart patient so will be at normal or low risk.
