The present disclosure envisages an apparatus for diagnosing cardiac related abnormalities in a patient. The apparatus comprises a repository that stores discrete pulse waveforms with identified features and threshold values related to a patient suffering from at least one cardiac related abnormality including a cardiac artery blockage. A plurality of sensors are placed on the radial artery of the patient to sense pulses of the patient, and generate corresponding pulse signals. These pulse signals are conditioned and converted into digital signals. The digital signals are then analyzed to detect a plurality of features and their values which are then compared with the features and threshold values stored in the repository to diagnose and determine at least one cardiac related abnormality.
